This video is designed to be a guide for testing and troubleshooting your TV repair. Please note that other complications may exist that aren't addressed in this guide. While we always strive to provide accurate and detailed information, we can't guarantee that it will fix your TV's issues.
We are going to take a look at the different boards on the back of the plasma TV and describe what each board is responsible for and the common problems or symptoms that can be shown by a TV and which is most likely responsible for those problems and symptoms.
So, the first part we are going to look at is the power supply which is right here. The power supply takes in and distributes power throughout the TV. This board is either directly connected to your AC power cord or is connected to the AC adapter. Some common problems that can happen with your power supply, is that you have a dead set or your TV does not turn on and you have no standby at all, then you know that you are not getting any power to the TV. You could have a situation where you do have standby, but you can't get the TV to turn on. That could also be caused from your power supply. You could have a bad power supply also if your fuse blows. This power supply has a few different fuses.
The main board which is located over here typically manages your accessory inputs and outputs and houses the TV tuner. So this is what sends the signal from your HDMI ports, your RCA connectors, your VGA input, all your different inputs go through here and are connected elsewhere to get the picture on the screen.
If the set in total resets on its own with you doing anything, it could be your main board that is causing that. If you are having issues with the video on the screen it could be a connection here or the main board is not allowing you to have the full resolution or clear image. Again if any of these inputs don't seem to be working with your TV it could be a bad connection here.
The y-sustain, which is located right here can also be called a y-sus board, a y-main board, and an SC board. So the y-sustain here, connects your PDP assembly through a buffer system most commonly known as a y-buffer or y-scan drive. Which is right here. Some common symptoms of a bad y-sustain, the TV shuts down and power cycles. That would be your TV turns off, and then turns back on again and then turns back off and such. So its running through a power cycle. If you have no picture on the screen, this could also be the y-sustain or if you have a dark picture on the screen. If you have a flashing screen with shadowy sections, this could be the y-sustain. If your TV makes a popping noise, which is usually quite loud and then you have no picture on the screen, this could be caused from the y-sustain.
So, the y-buffer can also be known as a y-scan drive. This y-buffer again is what connects the y-sustain to the panel. These orange colored connections right here are built into the actual TV panel and are what connect to the y-buffer. So if you have a problem with any of these ribbon cables here, they will not be repairable as they are connected right into the panel.
A common symptom of a bad y-buffer board is if you have black horizontal lines running across your entire screen. They would run from one side to the other.
Over here we have the x-sustain board. Common terms for the x-sustain board is x-sus, x-main, z-sus, z-sustain and SS board. Common symptoms that your TV is showing that could be the z-sustain is you will typically have a picture of some kind on the screen, but it tends to look very red or purpley, the picture could be very dark and flash a little bit, you could be getting slow-motion effects on the TV as the panel isn't charging and discharging pixels correctly. So that can be some common problems that could be your x-sustain.
Next we are going to take a look at the logic board. This board can also be referred to as the main logic control board, the control board and the logic main. The logic board is connected to the main board and address buffers, via flat-ribbon cables and can sometimes be hidden underneath the main board.

I fixed my plasma TV after watching your video, plus a new part from Ebay.
Hi Jimmy. When i plug in my TV it turn on and tick 3 time and power off. I took it apart and check inside. When i plug in the cord from main onto power board the main board flash 3 time and my dies powers off again. Is it my power board or main board. Please reply.
Good day, your overview of Plasma TV presentation was second to none. Although you had not touched on audio processing of it - I had really enjoyed it. Much appreciated.
Thanks Jimmy for actually inviting us to ask you Q's! This video is great, and after watching it I believe I may know which board I need to replace, but wisdom says I should lay it out before you as well, for your input.
My tv is a Panasonic Viera 65" Model # TC-P65GT50 (manuf in May 2012)
the problems started after a freakingly powerful rainstorm blew up suddenly here in the midwest. the living room window was open and the side of the tv that has the main board was approx 12" from the open window, and the back of the tv got doused breifly with rain blowing in the window.
Symptoms mainly affect what is happening on screen. we can be watching Cable or our Amazon FireTV stick, and suddenly out of the blue, the TV MENU graphics will pop up (as if I had pressed the MENU button on the remote), or the INPUT graphics will pop up on the screen (as if I had pressed the INPUT button on the remote), or the MANUAL CONTROLS graphics will pop up on screen (as if I had pressed on of the manual control buttons [PWR, VOL +/-, CHANNEL +/-] located on the lower right side of the unit. When these events happen, I often lose control of the unit with the remote, but sometimes the remote will still work (although rarely). When the INPUT graphics appear, it looks like a toddler has gotten hold of the remote because different inputs appear to be selected in rapid succession. Sometimes the remote is not able to control the TV, and sometimes I can 'fight throught it' with the remote and go back to the input that I want to watch. When the remote goes dead, I have to get up and physically turn off the unit with the manual power button. We can for for a long time (guessing 45 mins?) without a problem, or it can happen multiple times in a single minute. This has be going on for maybe 3 weeks. When it first started, sometimes the volume on the unit would just start increasing by itself, reaching mas vol in say 5 seconds or so. this does not happen anymore.
So, what do you think? Do you think the rain fried some component on the main board?

what about thin vertical pinstripes across the entire screen? shows black on a color test image. equidistant from each other?
I'm not sure but ,if anyone else needs to find out about

try Saankramer Electronic Magazine System (do a search on google ) ? Ive heard some awesome things about it and my mate got great success with it.
@@mercylopez5181 I did a google search that’s why I’m here 😂😂
Great tutorial, My 60 inch Samsung Plasma started putting a thin bright green vertical line down the screen about 8 inches from the right side edge. I was bummed out and was looking for a new LED TV, I got used to the great blacks that Plasma TV's have and really didn't want to spend around $2500 for a OLED TV that have great blacks.
Found your posting and you described the symptom my plasma is having so I am taking a chance and ordering a Main Logic control board off of ebay, was only $15 so no big deal if it doesn't fix it.Thank you for the very informative post.
Can I change plasma screen panel to an LED TV
I realize this is an old post, but did you get the logic board installed and did it fix the vertical colored line?
I really appreciated that you haven't taken older videos down. I have a, Samsung 5 Series plasma. Been going strong 12 years. A couple of months ago I got the occasional popping sound but everything was fine on screen. Recently i get kind of messy looking flashes or overlays on the right side (looking at the TV) which were just flashes to start with but are getting more frequent and staying longer. Its like a whitish cloud or puddle tinged red, very grainy and with evenly spaced dark horizontal lines.
So according to this video I have both boards gone? X AND Y? Because in another of your videos you ascribed all those symptoms to the Y board alone (unless I misunderstood).
Hi. Really informative channel. Glad I found it and subscribed.
I have a Samsung 50” plasma about 15 years old. Recently the screen has started to periodically go black but I can still hear sound. If I unplug it for several minutes, the picture comes back one. It does this every few days. The tv doesn’t have to be on for a long time for this to happen. I noticed it is also a little warmer that it used to be when I walk by it. The model number is HPT5034YX/XXA. Thank you very much in advance

Hi Jimmy, My TV has 2 thin black horizontal lines - Samsung PNC50C450B1D. My guess, I will eventually need to buy a Y-Sustain Board. Can you confirm, and indicate cost and difficulty if I want to replace it myself? Thanks, Chuck

Hi I have a Plasma Display Model: PS50C430A1 can it has black lines and sometimes it spreads a little bit
ShopJimmy.com I have a Panasonic tc-p50s60 plasma tv. When power is hooked up the standby red light comes on steady, no blinking. No audio or video. The fuse on the power supply board is good. I'm thinking I need to order that board from you. Am I on the right track?
I have a LG 60pv450 that shuts off after a few seconds of running. There is a standby light but it won't power back on after it shuts its self off. The screen will light up but it goes off again right away. We did have a fuse breaker pop this summer and it's the same plug that runs the tv. Would this just be a fuse in the tv I could repair? Thanks
Jake T im having the same problem with mine. did you find a solution yet?
me too
Me 2
@@emmanuelngakane6883 it's the powersuply
I also have this same issue, mine will turn on and we'll do fine as long as it's only displaying the no signal icon that dances around the screen, but if I power on a PlayStation or DVD player and the screen gets more I would say power or light in it it shuts right off
nice video...very well informative and easy to follow..;) will try next week , as our tv has no power...hope i can fix it myselt .excited , thank u for this video.
Great video! Very informative. So I've got a Hitachi model 42HDS52A plasma TV and there seems to be a cooling fan that runs continuously even after the set has been turned off (red light). I wondering if maybe there's a relay that's acting up(?). This particular set has a master power button that cuts power to the set and I have to turn it off to get the fan to stop running. Any thought will be greatly appreciated.
I have a Samsung PN60E530A3FXZA plasma TV that wont turn on. Several months ago it developed a problem where I would need to turn it on, see nothing on the screen, hen turn it off and back on it it would then work. Once it came on it was fine. Now I can not get it to come on at all. Maybe you can suggest which board might be bad. I have the back off and do not see any obvious issue such as bad or leaking capacitors.The RED LED on the front blinks and then goes out so I am getting power.
I have the same exact issue with the same tv...
did you find a resolution yet?
I replaced the Y-Sustain Main board with a used one I found on eBay and that fixed my TV. You can also find someone to repair your bad board on eBay.
@@LesLariz I have a 30 inch LG Plasma EDTV from 2008. Works great, BUT I have to turn it off and on 3 - 4 times to get a picture! Sound comes right on. Who can replace a "board" not me - who do I go to?
When i turn my tv on it stays on 1 maybe 2 seconds and then turns back to the red dot

Great video. My mitsubitchi tv - the program playing starts to have a semi- slow motion 10- 20 sec before it shuts off. Ever heard of this? Ty!
Great video thanks
My TV is a Samsung PS51E531 and had a few vertical thin colored strip[es close to the right hand edge.
There are maybe 10 stripes across a width of about 15mm (half inch).
I bought a smashed TV and have swapped the logic board and re-seated all the ribbon cables but no change.
I suspect it may one of the screen ribbons so that would be game over.
Any thoughts?
My TV fell out of the back of my truck on the highway and an 18 wheeler hit it with 9 wheels. When I plug it in, the screen shoots out fire. Which part do I need?

TV won't turn on with remote or switch button
Great video. I have a Tatung P46T Plasma. It will go into standby mode; however, when it is turned on, it begins making the loud popping noise you mentioned, and the colors on the screen are distorted with no definable picture just ghost images.
Hi, very intuitive video... I have the Samsung D550 51inch 3D plasma TV ... Recently we heard a popping noise and we lost picture. There was sound was still playing until we tried other av sources and couldn't get back.
Any idea what could be the specific problematic board?
Excellent video, thank you for sharing.
Hi guys, thanks for an awesome video! I have a Samsung PS60F55AK it has around 20 vertical colourful lines, can I fix it or should it go the way of the Dodo?
Great video! I have a question...
I have a Zenith Plasma TV (Z42PT320-UC) where the sound stopped working out of anywhere. I'll turn the volume up, switch HD I outputs and even use the AV cords, but no sound comes out at all. What would you recommend?
Hi, I have a TX-P42GT60E. It power off and on intermittently. I can start from the remote control, but anytime i push another button on the remote: to change channel, to open the menu, the TV powers down. Any advice? I read in some forums that it could be the power board.
Thanks in advance.
Thank you for the video. Very informative.
I have a 65” Plasma, 65” Plasma: PN64H5000AF
Version#: TS02
Serial #: 01UQ3CBF900283T
Last night I heard a “pop” and it died. No standby light, nothing. Won’t come on at all.
Opened it up and checked the power board fuse (250v) and it appears to be dead according to VOM. What do you think?
Jim
just watched your repair tutorial and it explained a lot Thanks, I have a Samsung Mod# PN51F4500AFXZA Version#US02
type #PN51F4500 . We had a storm and a few lighting hits near by and our other tvs work fine but the one listed came on and
has a pop up " no HDMI connections" tried different configurations no good . on HDMI-2 i get a very discolored pinkish red and distorted image that goes in and out. i hooked up an digital antenna and get great pictures. no HDMI .
based on the video the main board / ss board ??
Thanks for your passion to help us plasma TVs lovers ( have Panasonic 65 plasma works perfect for 10 minutes
looses picture has sound eventually 7 red light flashes
Awesome !!! thanks for sharing this wonderful knowledge about Plasmas!!!. I have a Samsung ps51e8000gr Smart TV that has Black/white Vertical bar about 3 - 4 inches thick from top to bottom. Is it ok to conclude its the bad logic main? I am all set to buy a replacement through ebay, but will wait for your final confirmation. Again, i just want to try if this could actually fix my issue. Thanks for your effort.
Hello, thank you for the helpful video. Based on your descriptions it sounds like my “Y” board is bad as my Samsung Model Number PN57D7000FFXZA cycles on and off. It begins with just randomly turning off on its own, normally within 5 minutes of turning it on. Once I turn it back on the shut off time comes closer and closer until eventually it just continually cycles to the Samsung logo and then shuts off and starts again. Do you think it is the Y board?
Good day.
Thank you for the video. It is quite helpful. My TV screen started turning pink in the top left corner. As time goes on this patch is getting bigger and i noticed that the pink tint is noticeable now from the left side to the right side (especially on white screens) but gets better as the TV warms up.
From your video it sounds like i have a possible issue on the X Sustain board. Is the board repairable? I have heard that some of the capacitors needs to be replaced. I would greatly appreciate your feedback on this.
Hi Jimmy excellent video! I have a zenith 50" model 50PC3DB. I believe the problem is with the x-sustain board because I get thick vertical black lines, after warming up the problem goes away. What do I do?
Great Video. One thing i'v noticed the Plasma TV's from 10 to 15 years ago.
They were built. My friend has a 42 inch Sony KE-42XBR900 Plasma TV which he got like 15 years ago.
It weighs 100 pounds. I remember Fujitsu made a 63 inch Plasma TV that weighed 160 pounds
I have a insignia 50 inch plasma TV NS- Pdp50hd-09 at first no power just dead so I replaced the fuse and it came on but now it has no picture just sound. So I switched some fuses around still the same. Now what does it need I'm thinking a new main power supply board? That should fix the problem? What do you think I hope I don't have to throw away the tv because i like it even though it tends to get hot but I'm a little frustrated now.
Hello man, Great video! I solved issue with purple snow (just bought external stabilisator). But my plasma won’t adjust from 43 of 60 overall brightness. From 1-43 it’s ok, but after 43 plasma don’t increase light even on a maximum 60 of 60. And overall feeling that plasma became more dimmer. And Vivid color mode don’t work at all. And the buzzing sound from plasma became very low, almost not recognizeble. Could you advise, it’s SS or A-board issue? My plasma is Pr50ut30, do you have some boards, if I want to buy?
Hi wow! This is great! We have a Samsung Pn51d530a3fxza. The tv turns on and we can hear the input from the antenna input. We have a black screen that sometimes shows a little faint static on the viewer’s left side of the tv that then fades quickly to black and no picture. I’ve already repaired the on/off switch board on the tv a few years ago.
Hello Jimmy, Thanks for sharing this video, it was really informative: I have a Samsung PL64F8500 which stopped working after a pop sound (like a capacitor pop), now the power lights do 5 double-blinks and starts all over again. I will really appreciate your thoughts, Thanks
Wow! That’s all very informative! Thanks! I have a 55” Samsung Plasma (not sure exact model # cuz it’s not with me at the moment) but on the right side, it has colored vertical lines. Any ideal what may cause that? Logic board, perhaps? As you stated in the video? Thanks! I really appreciate the info.
hi, thank you for your video - really super helpful. i have a samsung plasma - pn50c450b1dxza. it has some vertical colored stripes or bars on the right side of the tv. it happens more often now as the tv warms up and then stays that way. if i let it cool down, it will go away again until i suppose it warms up and the vertical bars start again. so it seems like a slow thermal failure of a board in the tv. i think it might be the logic board (pn i believe is BN96-12953A) as explained in your video or perhaps the E Address buffer ( pn i think is BN96-12954A) on that side of the tv. or maybe both? i am not 100% sure. so question to you is what do you think it is?
thank you
I have a Panasonic TH-50PZ80U plasma tv with a 3" wide vertical black (dead - top to bottom) band about 9"
from the side. Could it be the A board? I've replaced the TNPA4442 board with no improvement.
Hello! I have a TC-P65ST50 that started having interference lines/flashes and then stopped delivering input entirely on all ports. We've never had an issue with damage, pixels, it turns on and we can see the "no signal message" floating around. Looking for instructions on diagnostics, parts, and DIY repair. THANKS!
Hello!
Great informative vid.
From what you said in the video, sounds like my Logic Board is bad. I have vertical line in the middle and left of my screen when on. What do you think and what is the part # for the Logic Board.

Hi iI have a Logik 50" Plasma tv Model: LLPM-50.
When I switch on the screen it just flashes the correct visual for a second and then just random colours. The keypad is locked and the remote is missing. I was wondering if you can help out please.
Hi Jimmy, thanks for your resources. Pls I have a 60"LG plàsma tv that comes on some days and doesn't other times and whenever it comes on when you try scanning for Channels, it suddenly goes into standby and then refuses to come on again. It's a soft touch. What should I do please.
Thank you for this - here is how I successfully used this knowledge to fix my Philips (Samsung boards) TV. From the description of faults, I suspected the X and/or Y sustain boards. There was a picture, but it had an out of range color stripe and was grainy. Fault happened while watching and there was a burning smell. TV continued to work somewhat. When I looked at the X and Y sustain boards, I could see some bulged capacitors - they were all 82uF at somewhere around 312-350 volts. Between the boards, there were about 18 of them. There were a couple of other bulged capacitors. I removed them and measured ESR ( a good way to tell if a capacitor is bad). Turns out on these Samsung boards, those 82uF capacitors have almost ALL failed; only 2 of 18 showed ESR anywhere near acceptable. Now, if I were to just replace the boards, I'd be getting boards just as old with capacitors just as old. Ordering new caps from DigiKey cost about $60, and I replaced all of the 18 82uF, plus about 6 others, 4 of which were not even bad. TV is perfect now. Summary: many of the capacitors in your sets are probably at end of life, and if you look closely, you will see visual signs of this (bulging at the top). You may find, as I did, that a ton of your caps were bad, and replacement is inexpensive, and a much better option than buying old boards with the same, old caps....
Hello, you mentioned that you might be able to help with an issue. I have a 2008 AVP504 Sanyo 50 inch. Way back the top of the video became dark but we could see the bottom half of the picture. Well of course not long after the bottom half did the same and away it went into storage. Been sat there, inside, warm comfortable, and ir is now that I have time and inclination to fix this bad boy. Any suggestions as to the cause and how to proceed? Thanks so much!
I guess this is quite an old video bit hopefully I can get a response. My TV model is an LG Plasma 42PT350-UDACCLLHR. We were playing a game and the TV shut itself off. No loud pops or anything like that. The standby light is on and when we try powering it on it sounds like its going to start up but then shuts itself off again and goes back into standby. From your video it could be the ysus or power supply? Just wondering if its worth fixing or just buying a new TV.
Jimmy, I have a question about a Lg Plasma in a 60 inch model LG PB6650., the television was working during a thunderstorm and it shut down during this time, the standby light is working correctly and when powered up it goes off which is normal, also the screen will display a dark picture to lighter shade for a second at that tie it will power off and automatically back on by itself all the tie the screen is continuing to be black. I have replaced the power board and that did effect the time the lighting on the screen is lighting up more briefly till it powers back down and back on again by itself. Could you or would you suggest what the problem could be?
Hi I have a Lg60pk590 plasma standby light on goes off as it should do when I press power button but no picture on screen just black or really dark I purchased a y sustain board from eBay and switched it out with no success and tested buffer with multimeter power off? I have read about testing for sound but as i cant see screen im not sure how i can do this as mx box pauses when hdmi unplugged and thats really the only device i have Any advice appreciated
Thanks
Thank you for the video. We purchased our 42" Samsung Plasma HDTV in late 2006 and has given us flawless service since that time. I have it connected to a TrippLite HP1000 UPS for a seamless AC Source and power down. Just in the past week I have noticed that the TV has a grainy appearance during power up, and has a slow pulsating appearance with the grainy picture and it all goes away after about 1 minute after power up. No other issues. The picture is good without any lines or abnormalties. The model number is HPS 4253X/XXA S/N B15G3CNLB08739; Mfg Date Nov 2006
I have an LG plasma TV model: 50PC3D When turned on with the power button the screen displays a dark black and grey snowy image with a kind of black hole in the middle of the screen. There are vertical lines present and the screen seems to strobe as if it is surging. This is my first TV repair but based on the info learned in your video seems likely the logic board will need to be replaced? Your feed back would be appreciated as I am going to wait on ordering any parts until i get a response. Also I live in Alberta Canada and also would like suggestions on a cost effective yet quality source to order parts from? Thank you and happy holidays to all.
I purchased a main logic control board from ShopJimmy for my Samsung Plaza PN51D450A2DXZA as I had vertical lines from a power surge. Board replaced but still the same vertical lines. What board should I try next? Thanks.
Hi Jimmy, I just saw your video and I wonder if you can help me with my Panasonic TCP42X5 . The tv turns on and has a great picture but it randomly turns off at different times. I have to wait about 10 minutes and I can turn it back on and start all over again. Hope you can point me in the right direction and it is not to expensive. Looking forward to your reply. Thank you for your input.
Jimmy I have a model S4342 SamsungPlasma tv. It has a common issue on all video imputs. It comes up with a green screen on any imput. It went from working well to not working at all. The tv has a wonderful picture so I would love to fix it. Any suggestions would be appreciated.
Hi I have an LG 50pc3dh and it has vertical color lines. Any idea what this might be? Logic board maybe?
I have a LG 50PG25, 50-Inch Plasma TV that started out as 1 but now has 2 white vertical lines running from top to bottom in the center of the TV. When it first appeared the lines would disappear after the TV warmed up for a few minutes but now they don't go away. Also, sometimes when I change channels the TV may turn off briefly and then turn right back on before it goes to the other channel. What could be my problems and what components do I need to change out?

I thnik is configuration from Main Board
Panisonic Plasma TC-50S2 - Powers on and 2 to 3 seconds later the power supply clicks off and give a 10 flash code. The screen does not power on during the 2 to 3 seconds before shutting off again. I have disconnected both the SS board and SC board together and single, and the power supply continues to click off within 2 to 3 seconds. The power supply board (ETX2MM806AEL) looks okay from a visual inspection of the components resistors, capacitors, and so on. I've done some in circuit testing (I know in circuit isn't proper readings) and not finding anything that gives me any issues to look further into. I do not currently have an ESR meter to test the caps in circuit, otherwise I will be removing the caps to test off the board. Any suggestions will be greatly appreciated.
Panasonic TC-60PS34, built 5/2011. Have been getting white screen (like looking through cheesecloth) with sound for about a month, when turning on. Turn on and off a few times and it worked fine. Now it is just white screen with sound. Open back and everything looks ok. Boards are TNPA5343,5344,5399,5400 PH0914,PA5326. Do you think replacing buffers 5343 & 5344 and board 5399 will fix?
Hi, I have a Philips Plasma 50PF9731D/37 with White & Red vertical lines to the far right of the screen. The TV almost makes a loud buzzing noise when it starts up but tends to dissipate after 15 minutes. I appreciate your help with any suggestions. Thank you!
Hi, appreciate your content, I have an lg60pk590, I have a single green line running vertically down the screen, can you offer any advice on this?
Hello shop jimmy you guys are awesome. I have a pn60F8500 Samsung plasma tv they say this TV is still worth repairing and that’s just what I’m trying to do. After reviewing videos for weeks on end I have come to the conclusion because my television has no standby light and no power to it whatsoever that it is my power board. Because of this I ordered a new power board I have installed it and the TV is still not powering on help. I have also tried to test the cable going to the main board but I think that is past my area of expertise
Jimmy I have a Samsung mod. PN50A450P1D I saw your video and I think the y board it bad I have a lot horizontal lines everything else it’s working well can you for any chance have a y board or recommend where to get it thank you
SP-P4251, sound goes out after an hour. Back on if turned off after 10 mins, then goes out again after some time etc... main board? logic board? power board(caps)? The caps all look fine, in fact it's a refurbished power board. I bought it to fix the black screen issue, worked like a charm. The sound was working fine too. The sound issue came about a few months later. I tried ordering a new main board (the one that has the sound chip on it, texas chip) still had the same issue. What do you think? Someone said it was the sound chip overheating. Can a heat sink be put on it and actually fix it?
Hey great video. I have a PN60E530A3FXZA Samsung plasma. checked your vids and thought it was the power board so ordered and changed it today. However still no picture, no sound? any suggestions. TV is dark when I press power directly I get a light blinking then nothing. any help would be greatly appreciated paid a boatload when I purchased it. just don't have that kind of cash to redo so have to fix
! help. W. romo

Hey, nice video.
I have a Samsung 43 inch plasma tv. Model PN43E450A1F. when you plug the power cord into the outlet the TV standby light will flash 7-8 times and nothing happens. After the 7-8 flashes the TV standby light no longer on. But if your press the power button on the TV or remote you can get the standby light to come back then it goes away. I do have 5.26v standby voltage at the power supply. I don't know where to go from there. Any help will be appreciated.
ok so after some digging my panasonic 2007 50 onch has bad IC chips on the lower half of the horizontal buffers i ordered part number xxxxx58 and should be good to go. ill post a video of the repair process (:
I've got an LG 60PM6700-UB plasma television. I've got audio but no picture, a black screen. I Had somebody check the Y Sus main board. They said its good. I ordered an upper buffer board and installed it but still have the same problem. I'm wondering if I should also order the lower buffer board. Do you think a bad lower buffer board would cause this issue? Great content, thank you
Thanks for your great video. I have a Samsung plasma tv 860fh-yb06 Manufactured 2014-06-02. The problem is vertical lines have appeared on the right side of the screen. It sounded like it might be the logic board. I'm not sure how i would get feedback from you. Again thanks for your help.
Jimmy, I have a Samsung PN64D7000FF that worked perfectly for 6 months after installing a rebuilt main board. The screen is now black with no sound. I replaced the main board (again) and power supply board and is still black. Any suggestions on which board to replace next?
Hello. I have a 2010 LG 60PS60 UA 60" plasma tv. Was watching it yesterday then all the sudden no picture black screen but still had sound. Powered down and unplugged from wall to let things reset. Powered back on Powered up like it should had pic and sound was working perfect. Then 2 mins later screen went black still had sound. It will continue to do this every time now. What's your thoughts? Y sustain board? Thanks for your time.
Hi i have a Goodmans xpro gtv42p the screen is blank with a horizontal thin line does this carry a fuse would it be the power supply or a board what would you think it could be????
Jimmy I have a plasma LG television model 50 pn6500
My problem is that my TV turns on and off. Would that be the Ysus board?
Hi I have a LG 60ph660v with no picture but has sound, I've been told it's the main board, can you help in any way, maybe even where I can get a main board for my tv. Thank you 👍
Sound but solid black screen suddenly happened. Thought it over heated, but that wasn’t the case. It’s a 2008 lg plasma tv 50PG20. Any suggestions and do you also sale parts?
pn50c490b3d samsung plasma 2013 plug into wall and hear clicking took off back panel unplugged from main board and clicking stops appears to have 3.7v standby voltage. Thinking it is a bad main board. Thanks for any future input.
Great video!
I have a 60 in. LG plasma. It turns on for about 15-30 min. then shuts off and won’t turn back on for several hours. What board should I replace?
did you get this fixed
I have a Panasonic TC - P50X1 Everything seems to work fine except I only have the top half of the screen working bottom half is blank. Love this TV always had a great picture and hate to see it thrown out hopefully you can find me in the right direction as to which board Needs replaced or any other possible causes for this thank you
i have a pioneer pdp-4350SX both the red and green standby lights are on, otherwise the tv is unresponsive. is that the power supply?
Having an issue with my samsung model pn63c7000yf. The set turns on and I can get audio but there is no video on any of the HDMI inputs. I have tried multiple cables on multiple ports. Get the same symptoms on all variations. Any thoughts? Thinking it may be the Y Sus. board.
Hi, my tv (lg 60pn6500) works for some times but I suddently lose image and get only vertical bars on the screen.... I'm being told it's probably the mail board.... Worth repairing it? THANKS!
I know this is an old post but I have a pn59d8000 3d plasma. (long story short) I tore my acl lcl and mcl which made me rather unstable my crutch caught a chair and i crashed into a steal rack in my kitchen and it and myself fell into the tv causing the tv to fall off the stand and I got about a softball size webbing crack with what looks a slight puncture or pin sized chip of outer layer. It wasn't plugged in at the time but when I did plugged it in and try to turn it on I get nothing. Probably just have to junk it but if you have any ideas that would be great. I'm guessing it would be just as cheap to buy new then replace as it was a 2011-2012 model
Ok, Samsung FP-t6374. Picture is great... Volume started changing randomly, cutting out completely and changing levels at random. Also switches to headphone mode on it's own. I also can't get any audio when trying to watch Netflix through the HDMI ports on my PlayStation 3. I can get the intermittent audio from my satellite, but no volume at all with the PS3 (both through HDMI). Tried a couple different cords too, to rule that out. My Hisense has no trouble with either, but it's a 36" and I want my 63" to work!!! Please tell me you know what I can do. Thank you! And thank you for your vids! Super helpful!!!!
Howdy,
My samsung pn59d550c1fxzc was working fine and then the hdmi inputs went dead. I unplugged all cables and then unplugged tv. Turning tv on again, my xbox 360 was the only device to work and that in input 3 and 4. I have no idea what is going on everything seems to be working fine but it just doesnt recognize the devices.
Have you seen this before? swap main board? any and all help would be appreciated. Thanks!
thanks for the video
Hi, I got a Panasonic viera plasma tv model no, TH-42PD60X, that will show standby light on when powered on, but no images will show. It also takes a long time to show the back lights turning on, at times when I touch certain capacitors on the SC board, I will get the screen to show, but if I were to switch the channel, the screen goes black. Can you help figure out this issue and best solutions. Thanks
Hi chaps. Thanks for a very informative video. I am reluctant to discard my 11 year old plasma screen thus I would like try fixing it. The screen has several vertical green lines which have developed in greater numbers over past years. It is an LG Plasma TV model 50PK590 -EZ. With reference to your video, it suggests that the problem is most likely due to the logic board failure. Would this be correct or, if not, is this problem elsewhere or even repairable? Many thanks in anticipation of your comments.
Same .. I have an 11 year old Tv i don't want to throw out either. Very informative video. I need to get the model number but I hope they reach out to you
I have a Samsung PN51D450A2DXZA N102 which powers on with a 5-6 second steady light on the logic board before it cycles off and repeats. I've tried the process of elimination of the y sustain and x sustain boards but can't get the TV to power on with an image displaying on the screen or the noticeable samsung "chime". Capacitors look good but I haven't put a meter to them yet. Any idea what I can maybe look at next?
I have a lg 50pn60t , I have a solid red standby light . Have checked power board voltages of 17v & 5.2v . Any ideas what to check next please
Model: PN51E450 (Samsung Plasma 55 inch
)
Problem:permanent, single, thin, magenta, vertical line, top to bottom on left side of screen. Could this be the logic board or would you recommend a different part? Thank you.
Really helpful tutorial ,my problem is a verticle bar is appearing on the screen at the left side .mine is samsung the same one in the video .
I know this is an older post but you seem to know what you are doing and your methed of explanation is very clear. I have a PN51D550C with the following sypmtoms------ Runs 3 Power cycles with relay clicking when plugged in. Will not power on when power button pressed so no picture and no stand-by led. X-SUS replaced for it blew output transistors yet, it did not correct the problem. When Either X or Y boards are disconnected the power cycle stops. What is strange is the power cycle stops when either one of the X, Y boards are disconnected. With both connected, cycling continues for 3 attempts and then tv goes quiet. PS Stops cycling with both disconnected or just one of them connected and does not matter which one is connected just as long as both are not connected. Hard to diagnose a prob with the x or y boards when neither one individually connected causes the power cycle. All voltage output from the PS match and hold what is printed on the board next to each connector. There are no bulged or oozing caps, no burned or discolored areas on any of the boards and no popped fuses on the PS. The logic board "heart beat" LED has a slow and long blink pattern when XSUS and YSUS boards are disconnected and TV when both are re-connected. There is no longer a stand-by led with any pattern of connected boards and the power LED blinks 3 times rapidly when power is pushed with no power on or clicks.(heat sensing buttons not hard buttons on this model) I love this tv and hope to fix it. I do have some knowledge of circuitry but lack the indepth knowledge of how each of the individual components communicate with one another.
PS51E530A3RXXT black horisontal lines, then two loud bangs and the screen went black. What should i replace? i see no damage or broken fuses on any of the boards.
Hey Jimmy, I have a 2006 Panasonic plasma that I love, model # TH-58PX60U . having problems turning on where it goes off and the red led power light flashes in sequences of 7. Sometimes after being on a while it shuts down and red light flashes in 7s. Today, no troubles. What I'd like to know is, what does that mean and could it be cheaper/ better just to buy a new tv as I'm guessing I may be throwing good $ on a 16 yr old Plasma that gets beautiful picture and had been in storage for some time. Appreciate your insight and hope to here from you !
hi jimmy I have a samsung plasma tv model number pn51e450a1fxza. the standby light is on but the main logic control board green light is not I have no picture is it the. which element could be bad.
Hello. I have a plasma Samsung PN50a400c2d manufactured in 2008. The tv wasnt used that much over the years. I have a section approximately 4 inches wide that is either solid black or colored vertical lines from top to bottom. I have replaced the logic board in center of tv and also the input board. I have had times where it will go away but once powering off and back on, it reappears. One ribbon cable on the center logic board connects to what I assume is a backlight board that goes across the bottom of tv. I have reseated and cleaned the ribbon cable ends. I currently have a ribbon cable ordered. I removed and swapped ends of the ribbon cable but lines remained and in the exact same place. I am not sure if the backlight board (I assume that is the board) can be replaced. Hoping issue with the ribbon cable but dont want to keep replacing parts without decent chance of it resolving problem. Any suggestions? Thank you!!!!
LOOKING FOR THE SOUND BOARD FOR a zenith plasma model z60pv220-ua would you have one available ?
I have evenly spaced red/white vertical lines on the whole screen and I can still see the picture but if I leave the same image for too long it burns on in red for maybe ten minutes
