EASY WAY HOW TO FIX PLASMA SAMSUNG NO VIDEO PICTURE ON SCREEN REVIEW TV HAS AUDIO SOUND FROM SPEAKERS BUT NO VIDEO PICTURE ON THE FLAT SCREEN PANEL THIS SERVICE TECH REPAIR GUIDE TUTORIAL CAN HELP YOU WHERE TO LOOK ON THE TV BOARD AND WHAT PART TO TEST. This may Help you with Similar Flatsceen tv sets like Vizio Sony Panasonic ect...HOPE THIS HELPS :-) No Video on Samsung HPT5054 check cap 680uf 35v on y-board near green fuse video tutorial guide help video - note- some blogs recommend replacing all 3 boards the 2 thin buffer boards you see on the left side connected with the y-sus board cause the square ic (chips) burn out on them which takes out the y board sometimes. in some worse cases it's a bad panel so it's a gamble. it the cost of repair is over 300 just buy a new 50 inch tv for 600.
parts i replace sometimes on y board f5700 fuse, c5709 capacitor swollen, u5702 transistor, q5501, q5306, q5500, q5304, q5303, q5302,
Please take off the ring and watch, just watching you do this makes me remember the time my wedding ring almost burned my finger off when it arched power to ground back in 1988 when I was still a journeyman electronic technician. You are doing GREAT !! on the videos that I see you hosting keep up the great work my friend.
dude, you nailed it! The ribbon cable from the T-Con was crooked in the clamp. I straightened and full screen! Thank you! I love your videos. You do great work. Thanks again for sharing your knowledge!
After watching your video I found that I had the exact same Cap that was gone. Further inspection found a Cap in the mirrored location. Now to get the new Caps and replace. Hope it fixes the issue. My model tv is PS-50Q91HD. Cheers for the help and instruction.
Thanks for the speedy response! If I unplug the touch board how would I turn the TV on? The IR sensor is on the touch board also. Thanks
Holy capacitor bulge Batman.... while watching this video , realized that several components were covered by the support strut.. removed it and the exact same capacitor that was bulged on your board was the same one on mine!!!! Bonus! will check for all the continuity , cold solders , etc....but ....thanks
Heres what I am looking at when its the IR function board. Unfortunately the power strip going to the board isnt one with wires, its one of those flat cables. Can I snip those just like I would be able to snip a wire setup?
Thanks for the prompt reply! The reset did not fix the problem :( I did some more research and it appears that the problem is either with the H-Board (Input) or the DG-Board (Digital Processing). I am going to start with the H-Board since it is only a little over 20 bucks. In the mean time can you recommend some make/models for the "audio/video" surround receiver?
Thanks for all the work and information you post. My 50" plasma went down yesterday. Sound but no pic. After seeing you online, I removed the back. All the caps you browse over look ok. I know they could still be bad.I'll get a meter and check all and the fuses next week. You don't mention or check the three large brown caps on the center board. (250V 850uf) One of mine, appears to be swollen. Could that be the culprit?
Hey awesome vid! So I have a 42"apex plasma it turns on but after a couple minutes it starts smelling like its burning,is that fixable? Or should I just invest in a new one?
Hi, great video. I want to replace the y main but how do you disconnect from the y buffer board? The ribbon cable is simple but I can't figure out the plastic connectors that connect the two boards. I have a Samsung 42 inch plasma. Any help would be greatly appreciated
Thnx for your vids. So far I've been able to fix 3 Samsung TVs (2 52in LCD and 1 40+ Plasma, all made back in 2006-2007) by just replacing capacitors. Thnx again!!!
Hi Tampatec and thanks for sharing. Really helpful. I have sound and power but no picture problem with Hitachi HDS69 55" Plasma. 5 yrs old. The only online help I could get on this model suggested replacing upper and lower "buffers". I suspect - have not opened tv yet - that it is Capacitor problem as per your Samsung video. Would appreciate any input on what buffers are and is it a possible problem and also how easy/hard is it to replace a bulged capacitor? Many thanks.
Hey Tampatec,
I would be grateful for some advice.
I have a samsung plasma, after its been playing for some time (20mins, 1/2 hour etc) the picture would start jumpering, flickering and once the whole picture went but the sound was there. Any advice on repair?
Thank you for the great Vids, Really pointing me in the right direction, I have a Problem with my Philips BDS4241V/00 Plasma Monitor. This happened before with exact same problem and went back for Warranty repair.
Symptoms were that there was a clicking and then would Finally power up, Eventually went to just Red stand by light and will not power on, Seeing as this is now out of warranty i am looking at the repair.... when i disconnect pixelboard from power supply board the screen powers up..
I have the Samsung T5054. Same exact symptoms as the set in your video. That same cap was bulged and fuse is bad. Can you recommend a good replacement part for that fuse? Google was no help when searching that location number besides telling me it was a 1 amp fuse.
That surface solder moounted fuse!! What is it called? I have had my plasma in the corner collecting dust for 8 months..and finally i tested this fuse and it is visibally and electrically blown! What ware these fuses called so i can replace it? Thank you!
so where can I get a yboard and a x board? is there any recommended websites to go to? GREAT video, too bad I am in VA I could use your help with this TV that just went black and has sound.... :(
Hi, great video. I have Panasonic plasma TV. The picture has gradually gotten quest over the last week. Now its totally black. Any suggestions?
Great video! We have a strange issue where we get no video output from component, RCA and antenna while audio works fine. The weird thing is that video DOES work through HDMI...TV is Panasonic Plasma (TH-42PD25). Any help would be greatly appreciated!!!
Thank you for the reply.
Do you have a video on how I should use the freeze spray?
hey been a shade tree repair man for a long time and im working on my own tv now ive got an odd one for me 50 inch lcd insignia bb brand love the tv been great for me i have a sparkly worm comes on the screen when warmer not the hole side about 8 inchs long comes from the side gos back in to the side blue with some red in it took it down cleaned just in case all caps good nothing looked bad and ideas thanks
I have a Samsung plasma that looks like the exact TV in your video and it is turning on fine, sound is fine, just no picture. The repair place I called said it might be irreparable. Is this true? What causes a samsung plasma to be beyond repair? Your advice would be great thanks :-)
hello sir, thank you for all of your videos, i learn so much from watching them. i have a samsung plasma tv model hp-s4253 that has no video. in this video you state that you should be getting 200v from vs and 60 from va, i am only getting 8 out of vs and 65 from va. should i buy the main power board or is there a chance its an X or Y board? TIA for your advice. -phill
Sanyo DP50747 50" plasma one day the picture turned a pastel color, fuzzy, sort of like when you put a computer in safe mode but you can see the programs on the tv while screen blinks rapidly and I also noticed that the back of the tv isnt getting hot anymore. sound is ok.
Hi, great video! I have a Samsung LCD tv and what happens is the tv goes black after 2 seconds. I opened it and the capacitors look ok, nevertheless I have bought new and will replace the once on a power supply board. Do you have any hints if that could be something different?
Have a Vizio VP42HDTV that I was told made a loud pop sound and then the picture went black. The TV powers up, and the light on the front of the TV comes on as normal, but there isn't any picture. I want to purchase the parts to fix it, but I just don't know where to start. Thanks for your help!
I currently have a Samsung hpt5054x/xaa that has gone black screen. The power is on and the supply is buzzing along, but no picture. I have not yet taken the TV apart to check in detail, but wanted to know what I might be getting myself into if I do start down the process of repair. Any suggestions?
Another thing I found today was that when the Vs and Va power was tested and neither got up to voltage and then slowly went back down to zero even though TV was still on (with no picture, of course) this happened with X sustain disconnected and with both disconnected. If Va and Vs are not right does that mean Power Board or will the Vs and Va get to voltage without a the sustain boards connected?
if you not getting right volts on Vs pin it can be power board but other bad sustain boards can cause voltage drops. call to get tv correct tv part 1 (877) 881-6492 / (952) 881-6492
LG Plasma 60Pz550.Started with a green horizontal line on top half of screen.Now when turned on screen backlight flickers and then stays on with a 1" long blue line in top left corner with no picture .I was able to pull up the volume on screen dail in the opposite bottom right corner but will get a ghost image of it on top half and the lower 4inches of screen.Stays on for a few minutes and then shuts off.
I have a Samsung HPR5052. I replaced the power supply about 6 mos. Recently It lost its picture and sound. I replaced the y sustain board and upper and lower y buffer boards. The sound returned but still no picture. Any ideas what i should look at?
I have a Samsung 43 inch plasma TV, model no. PN43F4500 that doesn't have video or sound. I replaced all the boards, still get nothing. With the back off I get a green blinking Led, five times wait a short period then it repeats it, on and on. Is this blinking 5 times a code for what may be wrong with it, if so where can I find these codes ?? the TV was manufactured in May of 2013, I purchased it on Ebay October of 2013, so it isn't that old in useage, was a great picture the best I have ever seen on any TV, when it worked !!
Hello I have a Samsung plasma 50" TV and replaced all the boards and I get power but I'm not getting any picture. Can this be from not having something connected the correct way? Also, the only board that I did not replace is the one that is next to the Y board.
I dont know if you even check these comments anymore, but here goes nothing. The tv had trouble starting, so i replaced 2 swollen capacitors on the powerboard and now it turns on fine. The TV turns on fine, there is audio, but there is no picture. Do you think switching that fuse might work, or could it be that If I broke something on the power board that it causes it to not show picture ? Also , i lifted the TV when the lid was off only from the sides, could it have bent the screen, so its not working properly now ?
ok so ive looked around alot of people are having it in grids or lines mine is odd it only comes from the middle of the side and gos back in the side 5 inchs away its cuved 8 inch long dose not go all the way up to the corner and it sparkles on some blacks more than others
Hello just a quick question on my samsung everything works, just alot of the time the audio cuts off, and the only way to get it back on is to turn the tv off, then back on....is something going out? or is a wire bad?
if tv speakers cut in and out on all TV's inputs like- DVD input and cabletv inputs audio too then check TV main board, most main board can have loose solder joints or failing amplifier part or overheating.

I have a lgpz550 plasma tv is power up, it has sound but no picture what sound i do?
Tampatec, I was at the page you provided the link for and was looking for the Y board part(s) link and cannot find it anywhere at that page. Can you help me out please ? My Samsung plasma TV has sound but no picture and I'm pretty sure it's one of the boards that has gone bad.
Hey, Learning lots from these videos! Question...I have a Vizio VW42L that owner heard a loud pop! Checking caps, I found the casing for one rattling around (CS 206) and I found the remains of another one desecrated(CS118). How can I figure out what kind the desecrated cap was? Do I search for some kind of specs sheet or what?
Hi Tampatec,, thank you for your tutorial video, i've a plasma LG TV 50pn4500, the problem is when i turn on, i've sound and no image, after 1min to 2min, the picture appears! what's the problem in this case, thank's. another question, how we know if the caps are bad but look good?
Tampatec! Wanted to thank you for your videos! I've learned a lot from watching you! I was wondering if you could help me with a problem though. I have a Samsung PN42C450BID Plasma tv and the touch pad on the side (button less) keep activating randomly. It either constantly cycles through channels, raises/lowers volume, or goes through the menu. The remote control has no effect on it once its on. I tried replacing that touch board but the problem came back. Any ideas?
Great video but I am wondering if you could narrow my search on the boards. I have a 52" Samsung plasma. When I turn it on, it stays on but with a black screen and a really loud buzz. Any tips would be greatly appreciated before I tear into the back of the TV.
+Chris P Same here.
+Noelle Kristin Any luck with your TV? I was in the process of moving so I am yet to fix it. I need my TV back, the 43" I'm using now is just not the same lol.
Oxygen454 I've got this issue. Did you ever solve it
Hello. I have a Samsung Plasma HP-T505 January 2008. I have no picture but I do have sound. Is there a specific Y-board for this model I can replace to fix this problem and is this the only reason I would not have a picture?
Hey Tampa thanks for all of the helpful tips!
I have a Maxent PDP Monitor Plasma TV model # P4202YD07, ( loaded with all Samsung boards )
It has no picture or lighted display.
I dont know if it has sound because it has no cable connection but the tv powers on & stays on!
All fuses test good, no swollen or leaking caps, no visual damage at all.
What are your thoughts.
Thanks again!
hello Tampatec. I wonder if you could help me! i m trying to open the back after removing all the screws (all of them) but i couldnt. seems like it's stuck. have and idea what is it about please??
Hey buddy, I have an LG60PC1D Plasma. The TV will power on and has sound BUT there is no picture - it is snowy & blotchy. Could this be a simple fuse or possibly a Y or Z sus module? Thank you in advance...
I have the same tv and thats the same problem i have now. I have sound but no picture. I took the back cover off and checked next to the green fuse like you said but my capacitor looks fine
But i did find 4 green ones on the center board that puffed up from the top. Is this my problem
No sound or picture when I turn the TV on. Blue light will come on. Getting 120v input but nothing on the test points. Obviously it's somewhere ok the power supply board but how can I narrow it down to the component?
Hi, could you advice what couse shortcut on x buffer board of plazma tv, as if to connect it to main x, then tv get rebooted 4 times. If disconnect from x main, then getting on, but no picture
I have a Sansui HDPDP4200A Plasma Monitor which stopped having video after I blew a circuit breaker while using a power tool on the same circuit. The Monitor was on at the time but after I flipped the tripped breaker back on the set turns on but no picture. There is a Samsung PDP Module # S42AX-YB01 in this unit. I was hoping you might help me out.
A visual inspection inside the unit revealed a bulged capacitor at C5040 on the ‘Y’ board and a real funky looking fuse at F5004 also on the ‘Y’board. The fuse seems to have some sort of white deposit built up on one end of it.
You now know everything I know about this or any other TV. Can you help with the information I provided?
Thanks,
Mike
Do you have a solution for a Lg model 50pn4500 with no picture but has sound
Tampatec I Have a 2008 42" VIZIO VP422HDTV10A. I just got a new power supply as the tv would not turn on. Now the tv has a stand by light ( Orange ) in color. When I turn it on it turns ( white ) but has no picture at all. It looks like it is off. No picture or sound at all. What board should I buy...?
thanks for the fast reply! :D can i do this with a muilt-meter? and also what is Vs?? thanks again
Hello. I have LG 60PA6500 Plasma with sound but no picture. It was taking a long time for the picture to come on recently but now there's no picture. What do you think is the problem? Thanks
Hi, I have a TV of Samsung PS-50C96HD and practically feel the 'sound but the screen does not turn on. Can you tell me what can be? I am Italian and his videos I realized shortly: P
Can write in a text more or less what I said in the video? I would be a great help!
Changed the capacitor due to it was bulged. Still no picture. What else could it be? Thanks in advance for your help!
Hey TampaTec great Videos and thank you for the help! I'm having the same problem with a insignia 50 inch plasma. the tv powers up great sound it tries to power up I see the back light blink but it just doesn't. I have already taken the back off and when I plug the tv in and power it up I here only one relay click on but not the other one also the led on the logic board blinks but it a slow steady blink on and off cycle about every 6 seconds.
Which board could be causing this?
I have a Panasonic 42" plasma tv model# TC-P42X1 manufactured in 2009 it doesn't turn on. It use to turn on but it would take a while. Now when i turn on the power button it only blinks red constantly. Can you halp me with this problem
Hello,
I have a May 2010 LG 60PK250 with what appears to be a power supply issue. The standby light Comes on, turns off, on, off, then stays on.
I received this TV used/broken. After inspection it appears it had some sort of surge through the main board. There were 2 blown diodes on the back side and a red audio connection had some black on it as well as a blue connecter. Not sure what caused these to apparently burn or Get really hot. I have replaced the main board and connecting cable from the power supply to main board. had a green light come on the logic board for a brief period of time first time firing it up after installing the new board. Now back to relay click on the power supply and only standby light coming on.
Not sure what to try next, Set had a significant amount of dust on the boards.
Thanks,
Jon
Great video, thanks!! My Samsung plasma powers on, but there is no picture or sound. All capacitors look and feel good. I checked the Vs and Va voltages on my power board and they hold steady at what the sticker says they should be. I also checked most of the fuses (I apparently missed 1 or 2 based on your video). However, one of the X board heat sinks gets dangerously hot. I had someone tell me either the X board or the plasma screen is bad and there's no way to determine which one it is. Is that true or do you know of way to figure out which is bad? I don't want to take a chance on buying a new X board (that I can't return) if the plasma screen is bad.
Hi matey, I've just replaced the PSU on a Samsung PSPF531801A as the TV would sometimes turn itself off and on. Now the TV now stays on, but after 20 mins or so, the picture goes out. When the picture goes out we still get sound? Can you help please.
when tv parts overheat they fail so use freeze spray to locate what part is failing after 10 minutes of tv being on, once sprayed on that part (transistor or ic, ect) the tv screen should come back on.. don't worry electronic freeze spray won't short out boards.
Hi. I checked the capacitors and i couldn't find any one that was "bulging". but when i unplug the x board, the tv stays on but no picture. do you think the entire board is bad?
TAMPATEC good morning just wanted to ask for a helping hand I have a 60 inch LG PLASMA with only one issue only when you turn it on the pictures is all blurry and fuzzy and flickers once it warms up goes away and then works perfect usually last about 10 to 15 minutes can you please give me some clues thanks
Hello tampatec. Thanks for the informative videos as I've been able to repair 2 LEDs and 1 LCD with your help. I'm working on my first plasma tv now. I've acquired a samsung plasma tv model PN60E550D1FXZA. When the TV has not been used or is "cool" it turns on with no problems and will stay on for as long as I want. Once I turn it off and immediately try to turn it back on while it's "hot" the screen will not light up but I will hear sound from the speakers. Per your plasma videos you've mentioned that when you have sound but not picture it's usually the Y sustain board. Do you still think that it's still the y-sustain board if so how can I test it to determine if the part is bad.
With the help of your videos Ill open it up tomorrow and take voltages when the tv is "hot" and will not turn on and see if I find any bulged capacitors or any noticeable abnormalities. Thanks again for your help.
have a LG 42 in no picture checked boards and found blowed fuse and transistor . replaced y board now tv works but after playing for 8 hours or more it cuts off and back on whats up with that .
Ok tampatec I have really good question. I have this same tv and I get no picture and I have question. I have went threw my tv twice and can't figure this out. Iam getting all my voltages to all the boards, fuses all good I don't see any bulging capacitors. Logic board flashing when tv powers up.y boards check good what am I missing

Hi, please help...I have a HP PL4260N 42" Plasma TV and I can't find anything on HP tv repairs. The power button normally is red for standby then turns blue when powering up but for some reason it goes from red to purple. I hear a clicking but the screen doesn't come on and is black as if it's off. Any help please. Not sure if I should just replace it.
do you know what it means or what it could be if the ysus board clicks when thw tv flickers. i dont know what it is but its one of shiney things like on the left motherboard like yours. its one of the silver things i think. tv turns on but flashes. any help would be appreciated
Tampatec, I've noticed a lot of your videos are a few years old. Do you still post on You Tube ?
hey my tv samsung has sound but no picture and i check all the capacitors are good what you think is the problem i watched your video
I have a Samsung PN51E440A2F Plasma made in May 2012. Checked the fuse and looked for bulged caps. Logic board greed led flashing. When unit gets power up there is a dark gray screen for a couple of seconds. I live in Tampa Bay and problem occurred during a recent lightning storm. Any ideas? I can bring it to you.
when testing the voltage, what pins do you test for volts?
I have a zenith 50 inch plasma TV model Z50PX2D and the screen does not come on when the TV is turned on. The little light on the receiver comes on to let you know the power is on but the screen stays dark. I read that the y subs board is the most common problem but I'm not sure exactly how to test it. Can you tell me how to test the board?
Did you ever figure out the problem? Im having same problem on same tv now.
hi i have a 50" plasma Pspf531801a that when powerd up just has a steady blue light , and noting else happens , any ideas ?
I have a Plasma Display Model HP R5052 Samsung TV that flashes from bright to dim for a while like a power surge is going through it. What is going wrong with the TV.
I got 209.8VDC on VS and 64VDC on VA. Are those normal or a bit high?
QUESTION????? My T.V have a delay when u turn it on, meaning u can hear every thing but u can not see no picture till 8 minutes after. The reason I know it take 8 minutes it's cause I time it my self and before it give a clear pic, it will flicker for 10 to 15 seconds before it will give a clear picture. Do u think it's the same problem or what and I check all the cap and none of them is mess upp
sometimes capacitors look good but are still bad. but sounds like power board.
I have a 50" LG 50PC5D that has power and sound but picture looks fuzzy and dark. Could this be a bad zsus board?
Hi, I am having a no picture issue with my LG 60PA6550 Plasma TV. I have fully inspected everything per your videos that I can say the following. The STBY light is on when the set is off. The TV powers on and the STBY light goes out. I get the relay click and a slight buzz from the Y and Z boards. Pressing the INPUT select button changes the buzz tones a bit. The voltages are all correct except the STBY voltage when the set is off is 3.2V but when the set is on it is 5.1V?? Seems wrong to me. The set was moved from a stand to a wall mount and was handled but not dropped or anything but then never showed a picture since. I guess I am concerned the screen is dead due to being moved. I hate the idea of changing all the boards to find out that the screen is broken itself. Any ideas?
I have an AOC L26W861 TV and I had a red line in the center of the screen. After the TV was on for awhile the line would disappear. About a month ago the TV screen went black. When I turn it on I get a red light and that all. I open it up and check the AC & DC current on the power supply board and it appears OK. I did a visual check of all capacitors and the rest of the boards and couldn't find a thing. I would appreciate any suggestions you mite have.
Thank You,
Dick
Hi I have been watching your videos all day trying to figure this out. I have a 2 y,o. 43" Samsung plasma that will not start but tries 2 or 3 times and red front light goes solid and then power does nothing unless disconnected/reconnected . X sustain board powers through Y sustain.When I disconnect power to only x sustain board, TV starts and runs w/o picture. Same result when Y Sustain disconnected. No bulging caps or other obvious visual cues. Is it the X Sustain or possibly something else? Is this thing trash or salvageable? Thanks!
hey tampatec i have the same model and same problem i think the same capacitor is the problem how do i remove that capacitor and do i have to remove anything to get to it
I have 50 inch hitachi plasma TV. One of the speakers has packed up. Does anyone know how to remove speaker. Remote isn't standard for the TV and can't get "setup" with it. I need to remove speaker. Any advice would be appreciated... Ta!

I replaced the y board and buffers from a parts tv, and i had a guy come check out the tv and he claimed the tv screen was bad. the whole screen. what else could be an issue....the guy who checked it out said all the circuits wer good. i heard it could be a transister issue.

LG 50PS60 Plasma. Intermediate sound with no Video. If I unplug the ribbon cable from Main board to Tcon board and plug it back it in I can make the screen work on command. When the screen comes on it is a great picture. All voltages except VS are on spec. Instead of 195 V, they are 183. Thanks for any help.
I have a Panasonic plasma TV Model TC-P58VT25. Following and loud and very close lightning bolt, I heard a pop and thenTV had no picture but does have sound. I am able to display SD Card information and also display the TV menu, but just get black screen when cable input is used. Is this likely a Y board problem? Also there is NO blinking red light (it just stays solid red).
I have a 50 inch hitachi plasma tv before it was blinking blue light well I found out that the capacitors were bad and also lower buffer board so I replaced them well being an amateur I made a mistake by putting one of the capacitors in backwards well it blew the circuit board again ......... ok so once again I installed new caps and lower buffer board so now I have a picture on top of tv and none on the bottom and the tv on top that is working is now fuzzy so my question is what do you think it could be thanks
Hi
My Samsung ps-50q96hd tv has this issue.
When I turn in on it clicks once then video (like vertical lines comes on the right hand side and then I press the buttons on the side then I get blue jittery screen) also a loud speaker static sounds comes on suddenly and then it then clicks and turns off.
What is the issue with this?
I have opened the back up and tested disconnected every wires from the powder supply board (pspf531801A) and then connected one by one and tested it would only click when I connected the main board (the one with the vga and scarfs and other connectors ).
I was wondering if you could help me out.
Thank you so much
Trutech plasma tv, would I still need to inspect it in the same exact manner you did although different brand? at first the tv worked perfect, then while turning it, the picture wouldnt work for a minute, then the display would appear and quality/etc was fine, then it went to 5 minute boot session to get display, now nothing at all, not sure if you are familiar with the problem I have but any advice is greatly appreciated
Hi I have a LG PDP42x2 Plasma. Sound is there but no Image whatsoever. I checked the fuse on the Y-sustain board and it was blown. I replaced the fuse and the TV poweron light will be green for about 3 seconds and then turn back red. When I remove the fuse the TV has sound again but no Image. Is the Y sustain board faulty. I dont want to buy a new board if its not the problem since it is such an old TV
I too have a Samsung plasma tv PS43D450A2 model with horizontal black lines in the middle part of the screen. The tv is fully operational.
The voltages on all test points of the power supply, y-main board test points read fine according to plasma screen stickerwith Va, Vs and Ve readings. The X main voltage at test point XS-E is 78V
But when i test the voltages across the smd resistors R5149 to R5154 and smd zener diodes D5504 to D5506 (marking PJ1389) on the Y-buffer board, i found that the voltage is fluctuating between 45V and 30V. It keeps dancing up and down on all the resistors and diodes across the y-buffer board.
I felt the ICs on the board with my fingers and they were all warm. Nothing too hot or cold. Is this a voltage regulation issue from the y-main board or a y-buffer board issue? Little confusion here ;-) The heart beat led light on the logic board is good. I have tried re-seating the flex cables on the y -buffer too. The only thing bothering me is the fluctuation in voltage across the resistors/diodes on the y-buffer board.
Could it be bad capacitors on y-main board? But the test point voltages on the y-main read ok. So the confusion haha.
Any feedback will be really helpful.
Thanks n regards
great videos very helpful, i'm learning stuff haha. I have an 08 lg plasma that has the right volts in the vs and va's and fuses seem good. caps look good, checked the buffer boards and one of the ic's is bad on the top one. The problem is there is sound and the screen is gray with a horizontal strip on top that is pixelly with different colors, but the screen is mostly blank any advise?
I have a Panasonic Viera 42in Plasma tv. Model 42st30 1080P 600HZ A. For a year or so it the picture and sound would suddenly go off, come on for a period of a few seconds to several minutes, then go off again. It might cycle through this for 15 minuted to several hours then stay on. This occurrence is random. It may be several weeks to a month before it recurs. I have had the cable company replace the box several times with no effect. A week ago it stopped completely both sound and picture. The power light stays lit. The remote doesn't turn the tv on or off. The mechanical button in the front doesn't work. I have pulled the plug without effect. The power light remains on when I plug it back in. Any suggestions?
I have a Sony KDE-42-S955, the picture takes 6 minutes to appear when we first put it on, I know something is going do you have an idea on what that might be before I invest in another maybe I can fix it, Ive had it for a good 10 plus years and its done me good all of this time. Thanks a bunch
+Richie L My mother-in-law just started having the same symptoms as you described on her 10+ year-old KDE-42XS955. The audio is not affected but the picture takes 5-10 minutes to appear, but when it does, everything is fine until the set is turned off for a few hours. Does that match your symptoms? Were you able to identify the source of this problem? Any info you can provide would be appreciated. Thanks.
Hey Tampatec, I got a Samsung TV with no picture but it does have sound. I see no bulged capacitors. Where do you think the problem is?
press tv menu, if tv menu doesn't show it can be y-sus board, get at shopjimmy.com but contact shopjimmy techs to confirm Y board is most likely fix. on "Vs" pin should read about 190 dc volts on power board to Y board.
Tampatec. Would this problem also fix my Samsung TV that has no picture and no sound? Mine turns on, makes the melody noise, and the blue light comes on. Lamp turns on too. I have an DLP tv, Model # HLT5076SX-XAA. Replaced the color wheel, but that wasn't it. (Waste of $100)
