- A Panasonic Plasma TV from 2012 gets town down and repaired to component level using nothing more than basic hand tools and a basic soldering iron.
Don't replace the entire board, fix it. Parts are cheap.
Picked one up free today and repaired it with the intention of selling it. The picture is so good I don't want to get rid of it now. I think my old Samsung is going to be finding a new home.
thank you, thank you. I'm about to try the exact same thing. first time I've picked up a soldering iron in over 40 year. Really nice to see someone go through each step.
Just wanted to leave a thanks here, I just brought my UT50 back from the dead for 15 bucks and very little soldering experience. The IC152 took 2 tries, but hey, the TV appears to be working again! Anyways, thanks again for the incredibly thorough video!
Excellent. Yes this was an easy one compared to some.
Oh I'm sure, I'm just glad I lucked out with only needing a relatively minor repair.
I LOVE plasma sets, the colour on them is just beautiful vivd and sharp, and i HATE the dull washed out colour of LCD with a passion, you cant compare the two really, its like comparing a mini to a rolls royce
You can just turn up the color in the LCD tv and it'll look the same as a plasma
***** No it wont completely different technology, plasma uses phosphu lcd uses crystal
+Ryan Scherbluk LCD and LED sets are the same. They use Liquid crystals to bend the light rays passing through the panel to either allow it through the second polarizing filter or block it. Color is added by the color filters attached to the panel.Plasma the primary colors are created by phosphor much like it was created in the old CRT. The difference is on a CRT the phosphor is stimulated by the electron beam striking the inner surface of the tube. A plasma set creates an electrical discharge through Neon and Xenon gas to produce the 4 state of matter, plasma. This plasma discharge produces UV rays, and those UV rays excite the phosphorous and make it glow.Plasma TVs, like the old CRT TV sets are cool. They also have a better picture. OLED has promise too, because it too uses phosphorous to produce color, but the source of UV light to stimulate the phosphorous is microscopic organic LEDs.
Thank you for explaining i couldnt be bothered
Hi 12voltvids. I have never seen anyone half as good as you are fixing TV's, thanks a million for taking the time to make this and many more videos on repairing TV's your work is second to none and I miss you making TV repair videos, for me I have never seen a better technician half as good as you truly are, I know you may very well may be not making any money repairing them, so for that reason I don't blame you as no one is going to work for nothing but it's a pity as I just can't find any anyone near as good as you, I would have to say it is because of your experience and time working on them anyway it is a pity as I said there is no one anything as confident as you are, I totally understand so hopefully you will be making more money fixing other units. I wish you all the luck in the world in the future. Kind regards always from Jim. 👍
That is a very important point about the screws !
I have repaired 2 of these tv's ( one upper buffer board & one y-main board) & I was sure that the loose screws were the culprit of the failed components.
This is the most comprehensive tutorial on these tv's on youtube !
THANK YOU.
Yes they are the culprit. Not just on Panasonic. I have had a few Samsung sets with the exact same problem. What happens is through heating and cooling, the metal chassis and screws are different materials, and they expand and contract at different rates as the heat and cool. This works the screws loose. This has been a problem with many electronics going back to when I got into electronic repairs in 1984. I can't count the number of failures over the years caused by loose ground screws.
So just like the automotive industry, they build em good enough to get em out the door but not good enough to last at least 10 years.
Don't know about that. The last few cars I have owned have been well over 10 years old before a wrench touched it. My Escape hybrid is 12 years old now, and the brakes were done for the first time at 110,000 KM. It has 170,000 on it now. My Volt is almost 6 years old and all I have done is repaired a few flats thanks to a nail in the road.
Be very gentle in prying the IC chip, or any component, because if the soldered leg is not liquefied, you run the risk of removing the copper pad. In which case you may have to scratch a new copper surface with a razor knife.
I've replaced larger components with excellent results. IC chips are now a nightmare to me lol
Wish I had a magnifying lens like yours. Don't like the one that came with my station, and my USB microscope wants to be too close to the working area.
Excellent tutorial though!
you videos are very informative, really wish I had going into electronics repair when I left school in the 90s, everyone told me there was no money in it but I really enjoy problem solving and repairing this stuff.
Jessie4Pink
there isn't much money in consumer electronics now. back in the 80s and early 90s there was more to be made. I left in 2003 as I could see where the industry was headed as far as consumer electronics went.
If Panasonic had used screws with lock washer in the first place this would have been avoided .I doubt the average consumer will open up their TV to re tighten all those ground screws and they really shouldn't have to . Again , another great example of poor engineering and assembly of today's throw away electronics with self destroying boards after warranty is barely over.
Rant over , keep up the great work
@Philip Turner
They fuck up time and time again. Yes sometimes it is overlooked but when problems are identified in the field and they don't make running changes then there is a problem.
This problem is not unique to Panasonic. I had the same thing happen on my Samsung plasma. Got the screws tightened before it went boom.
I really like how you go into great detail about all aspects of the repair, even the smallest detail about the application of flux and why, or the detail about repair kit and part numbers, seen a few of your videos now and I've really enjoyed all of them....keep up the really great work your doing, Oh and bye the way love your new 4k camera.

Looks like my Panny is on the way out, picture is flickering from perfect to washed out/distorted colors, and now i am occasionally getting the 8 blinks when i turn the set on. Your video is super helpful, i think i will order the parts (probably the SS board) as i checked for loose screws/connections. Would be a shame to see this TV go to waste. Thanks for this super informative video.
This was hugely helpful to me with replacing my A board in my 50u50 (turns out it wasn't a bad HDMI port, but a bad Displayport to HDMI adapter, so now I have a backup board!) I couldn't have done it nearly as confidently as I did without you (and the service manual! LOL). PLUS, now I know how to access the service menu (not that I would know what to do with it). Thanks!!! Do you have any guesses as to how much longer it has to live? It's been going for 9 years and I'm wondering how long the screens are supposed to last. Thanks again!! :)
I know you have seen on some of the old equipment and TV / Radios, the ground screws sometimes are Soldered to the boards so Ground wasn't lost and the screws couldn't become loose from the boards flexing due to heating up.
Yes it was very common to solder the screws down on many Sony receivers that suffered the loose ground problem. The problem is most screws will not solder unless they are copper, which is rare. Most screws are steel, and solder won't stick to steel or aluminum no matter how hot you make it.
I love watching your video's no messing about just replacing the board, you actually fix the problem, better for us Better for the environment, lots of respect for this, Great work. joe uk
I really appreciate that you took the time to make this helpful video. I orginally was getting 7 flashes and had a shorted SC Board - replaced that and then got 8 flashes. How committed am I to fixing this thing.as I'm just a guy with a screwdriver and an ohm meter... ? We will see.
Did ya get’er?
Man your good, my Panasonic plasma packed up, I checked all the usual, and you mention bad earths loose board , well I'll be dammed I tightened all the screws and she works, I've always, had a soft spot for this plasma, yet not comfortable with the very high voltage in plasma's, so I was careful, and my favourite TV which now lives' in my den works, my wife bought a 50 inch internet tv by Hitachi, I'm the winner with my Panasonic 50 inch plasma so thanks you taught a old dog a new trick.
The reason the ground screws work your way loose is due to heating and cooling of dissimilar metals. It doesn't just affect Panasonic I've had this happen on Samsung and the LG plasma screens as well but very common on Panasonic because the dummies didn't put lock washers on the screws to stop them from backing out and that's what was in the repair kit was lock washer screws
@@12voltvids I'll buy some lock washers today and fit them, that will be a permanent fix thank you .
@@paulcollins9839 it will stop the screws from backing out.
thank you for all the videos. this one in particular you helped me. i have a TC P50S30 I received it free on Craigslist. i tried cleaning all the connections and cables no luck. this video came up in recommended list and a light bulb moment.my issue is the same. the talking as you are working is extremely helpful and the explainations as well.
i cant speak for all but I'm sure there are alot of people feel the same
THANK YOU
Panasonic has the best troubleshooting in my opinion. The trouble codes and service manuals are readily available. I have 3 of these that only needed repair once and have been running great ever since.
s
+James Machalik I have 3 Panasonic plasma. 1 never has problems, 2 broke down. Both serviced on the channel. Not many faults. Panasonic made a good plasma. Samsung are also good but have had more problems than the Panasonics.
Fantastic well explained video. Glad to see that there is a way to replace those surface mount components without needing an expensive rework station. Very informative. Keep up the good work.
I have a Panasonic TH-42PV500V and whilst watching it just slowly died picture and sound, I wasn't aware of the 'blink codes' so haven't as yet checked to see if there are any but as I got a 'round tuit' for my birthday I will be investigating soon, hopefully my next comment will be a positive one, my electronics work has been mainly digital.
I'm about to take a look at my own, same model/problem. I can't seem to find a link to the troubleshooting guide, though, and that'd be nice to have even though this video is pretty encompassing. I'll have to practice soldering, I haven't done that much... ever... You don't happen to have any videos on basics like soldering, reflowing, etc? I'll look for others, but you're well-spoken with a good mic, which puts you in the top 5% of youtubers. Thank you so much for making this video!
At 15:55 you point to arcing burn at ground screw connect and there is also a burn on the red cable next to it so this was respectable arc.
Hi there. I just acquired (for free) a Panasonic TH-50PX60U Plasma, and it turns on, but the screen is black (with all lights off in the room, you can just see the screen "glowing"). Doesn't seem to respond to anything. Took off back cover, and the "health" Green LEDS are both lit up. Nothing looks out of place or broken...
Man, if my soldering skills are as good as I hope the are you will be saving me a ton of money and I get a free 50" TV.
I Was Talking To Uncle Doug About
Him Fixing Those Old Tube Radios &
TV's & I Told Him That Old Stuff
Isn't Worth Fooling With. Cause Those
Parts Are Too Hard To Find.
Some can be for sure, but even newer stuff is difficult to find parts for.
My tv now won't turn on at all--the display when turned on makes the usual 1 click noise when you first turn it on and then displays a black screen and stays there--with the red LED on the front bottom screen displaying power staying at a constant rate with no blinking. Whereas after this happens the remote doesn't work or respond to the tv, and also the buttons on the tv do not work at all--all buttons including the menu--yet the power on the tv is on TCP46st30
Thanks but as a newbie wish you'd showed which screws have to come off to get the back off.
maybe next time he can just come to your house and fix it for you
Hello from 2024. Literally every Panasonic plasma tv I have or have had, went through the pain of a failed board. If not the A board then the SS board. Frustrating. My 60” is now blinking 8 winks. Time to open it up. Again! Not sure which board it is this time. But I am sure I do not have skill to replace components on the board(s). In past repairs I replace the whole board. I am just crossing fingers that shopjimmy still has parts for this TV. Seems like I’m a fairly regular customer with them. LoL.
They reason they failed was the red screws that backed their way out and arced.
It's good to know about the screws tightening. My problems is to find out where I can get the repair kits for that board or other bothere. I"ve looked high and low for a decent schematic for the 32PFL5332D/37 Philips LCD television. Maybe it's the age of the set but I just can't seem to locate a wiring schematic. I'll keep looking.
Don't buy the kit. Buy the components separately. Most of the time it's cheaper anyway.
Excellent tutorial and job. I have same tv bought in aug 2012. Had same issue in feb 2014 and board replaced under extended warranty, now it trigrrred again after roughly 1.5 years and tv wont turn on with 8 blinking leds. Stll have extended warranty so lets see how it goes
+Pranav Bhatt Let me guess they replaced the board and didn't do the mod, so the same screws went in with no lock washers and the same thing happened.
+12voltvids : Yes thats correct. I bought the screws in Feb 2014 but Unfortunately didn't touch due to covered under warranty (I should have replaced the screws). They are going to replace the TV with some other LED model but not sure what exactly. Most likely I may not getting the PQ anywhere near to UT50 with newer replacement LED so thinking to replace the damaged component with new screws if not getting proper replacement
+Pranav Bhatt
I would replace the parts. Fix is easy and not that expensive. The pq of led / lcd can't match the plasma. Only oled can and they cost a fortune.
The video is indeed very informative, and for an old Tech. like me, a cinch to repair. Will order kit and go to it when received. Until thjen will put it aside and go on with the Sony in the shop with no video, and a Toshiba with sound but no video as well. Thanks. Bernard
Excellent tutorial, thank you for post, Sears through an extended warranty had repaired this 8 flash code and did SS board 3x, 2x after new television replacement, I think sears has apparently raped me repaired same SS board 3 times, and each time after new tv replacement,right side out, then left side out, they want 100 just to look at the same part replaced 3 times, this TV is well cared for, aside from the same issue---the first one my mother worked at sears as asset protection manager almost 20 years and got as an open box she purchased the sears warranty, within 1 year less than one year the left side initially went out they, and replaced SS board 8 blinks same thing on opposite side, as per Sears warranty team, They replaced yet another SS board after watching these and ss jimmy, i know they just took flat out advantage, i want to call Panasonic concierge viera but do not know terminology, Sears robbed me because they had no choice but to replace the tv because they couldnt fix, can you please help me, i love this TV, i love plasmas, i don't want to buy a new TV, I dont have a lot of money to fix it or have repaired my husband is on a fixed income, but does know about electricity and diodes, i bend diodes for him, his father is an electrical mechanical engineer, far from fixing televisions, sadly, but I know my husband can do this I have faith he can, but on the other end of the spectrum i think Panasonic should know what sears has done as far as robbing their customers, and I just do not know terminology, my husband and I both just watched your video, and it would be new waters for sure, but he is well versed with resistors, capacitors, coil relay etc. but what it has to do with being able to explain to Panasonic with proper terminology is what I am aiming for, as you well know when warraty fixed with Sears speaking with people from Panasonic is a totally different story, I was wondering if there is anything you can recommend? Am I wasting my time ordering the same part 4 times now? Should i just buy another tv? I do not want to, This TV is seriously pristine. My husband said when they originally replaced the screws they were arched because they didn't have lock washers, By arching depriving electricity to other components or on the flip side burning others out. So what do you think? Thank you in advance.He said a lot more, but I typed what I could grab. Thank you again.
The fault in this sets design is multiple grounds. The problem could have been prevented by soldering a ground wire to all the ground points around the board, or put in screws with lock washers. The kit I show is a repair kit that Panasonic sold to their dealer network that contains the components that usually fail when this problem happens. Not putting in lock washer screws is just asking for it to happen again. This set has been fine since I fixed it. It's my set now. It was my mothers set, but I gave her my Sony while I was fixing this one, and now she is in a seniors facility so the smaller set I gave her is a better fit for her room. I love my plasma TVs too. I collect them. I have 3 Panasonic, a 42 SD, 42 1080P and 50 1080P. LG 42 720P. 3 Samsung 50`720 sets and a Samsung 63 1080.p.
What are those cables called wirh the tape on them? I. Have one that's got a up and down cut on it how can I fix that? It keeps popping the su board when I tried to get black lines out?
I miss my old P50
- Picture was better than my 2019 Q-LED
- Soft whites, deep blacks
- Also it has a mind boggling 600 hertz refresh rate
I'm hanging onto my plasma sets as long as possible. 4k means very little to me outside my photography world and i have a 4k just for that.
I have a 2007 version of this set. There isn't a blank spaceon the panel, it's all filled with boards. I wonder if the picture quality suffered when they trimmed it down.
+James Last No the picture quality on the 2012 version is just as good as the 2007 version. I also have a 2009 1080p. It is loaded with boards.
I believe that I am having the exact same issue that you repaired so this is a pretty good find! However, I noticed a decent bit of brown discoloration where the short occurred. Is the board toast at that point or do you think that Jimmy repair kit will do the trick?
I have the same issue. Going to try this soldering out first, then if that doesn't work, try to find a new board.
I have the same on the back of the board, but the repair still worked in the end (not exactly a timely reply, maybe it'll help someone else...).
So, what exactly is the cause for the arcing in the first place besides the screw being loose? If all components and boards are functioning properly, there should be no current flowing towards the ground screws in the first place, no? Yet, I've read a few stories where people have replaced these shorted transistors, diodes, etc. and immediately upon plugging in the TV, they will hear the same pop and the same board they just repaired will have died again. Thoughts??
Panasonic in all their wisdom decided to use the metal chassis as a ground return. The 4 lugs on the corners of the board are NOT connected together using an internal ground. Therefore when one of the screws comes loose, that terminal, and all the components that are tied to it loses their ground bond, and the pad potential rises and eventually arcs to the metal chassis causing components to go pop.
They wern't the only ones guilty of this practice either, and it is nothing new. This crap was happening back in the 80's as well. Many sony receivers went snap crackle and pop when a specific ground screw worked its way loose.
Great Job was done with a cool mind, A lesson to learn from A Great
Man A Loving "person". Thanks....
I have a P50ut50. Made a pop sound when turned on and now just hear a clicking sound from a relay on the PSU. I already has the SS board repairs 5 years back. There is no blinking led. It is totally off. Just the relay clicking sound. Would you perhaps know what could cause this?
love your videos, I have a plasma tv with 1/3 of the screen blacked out vertically is that fixable? Appreciate any help you can provide thanks
That Plasma was defo worth a fix as looks quite new and has all the HDMI stuff to.
Hi, nice video! I have the same TV and i think that the IR SENSOR was broken. How i use a multimeter to testing the photodiodo or which types of teste i have to do to fix it? Please helpme with some tips... Thanks a lot.
Hi... Do you know what is the size of the screws on the kit? I'm not from US and I cannot find this kit where I live. But having the correct size of the screws would help me a lot.
Just put star washers under the originals.
Hi I have a Panasonic 65 viera cast 2009/10 version i believe. It went out after it was moved. I began to notice that it would power off on its own and I would here clicking sometimes. I also noticed that it did get very warm/hot too when it would be on. After reading these comments I am now aware there was actually an issue going on. I have not been able to take the back off and attempt to inspect but I will try today. I am not an electrician at all but I can be somewhat handy with tools. Do you have any idea where I can possibly order parts for this older unit and can you send me your trouble shooting guide? TC-P65V10 I do not own a sodder. But I will attempt to find one of those too. Thanks for your help your video was definitely a start in good direction for me! You have a new subscriber in me! Oh and I think it did very good my tv has lasted 10 years until now. So let’s see if I can get 10more
Oh it eventually powered off and I unplugged for a day powered it back on it stayed on a few minutes and went out again but the 8blink flash came back on. So I am guessing something is either bad or disconnected per your video.
I got the parts kit from shopjimmy.com
What screwdriver did you use to get the screws on the top middle off? They require a different screwdriver than the ones on the side, but I don't know what screwdriver. I ended up damaging one screw pretty badly as I was trying to figure out the right screwdriver.
Love the video. Fixed the as board but now have a silid standby light not pic or sound. Stand by voltage is 1.5v. prolly the psu huh
hello I repaired my TV but it only stays on for 2 minutes and shuts off with 8 blinks, I disconnect it wait a minute and connect it back again and turns on again for another 2 minutes and repeats failure, do you have any idea what might be happening?? already checked bolt torque and connections
your video was very informational for me where do you get the parts need a ss board.
I have a PT55UT50 that blinks THREE flashes of the power light. Does anyone know what that code on that model is? If there was a troubleshooting manual for the 55UT50 I would appreciate getting a copy.
I have the exact same tv. I used to have the led blink code guide and now that I have time to work on it I can't find the guide.I've search the internet with no luck and I saw the link that you posted but it didn't work. I would appreciate it greatly if you would let me know where I can find it. Thanks for sharing the knowledge!!

I have FILIPS 42PF9966. hard turns in the morning when it is cool.
When you turn it on after 10 to 20 attempts red light flashes me one and 8 times in succession.
If you turn it off while hot and turn it on again, then fell without problems immediately.
I do not know what the problem is, so please help me. Thank you.
+nikola mijatovic OK if I understand the question the problem is only when it is cold. If you turn it off when hot, and then back on it starts fine, but when cold you have to try turning it on multiple times to get it to start?That sure sounds like a capacitor problem, likely in the power supply. I had an LG42 plasma a few months ago that did exactly that. When cold it had to be turned on multiple times to get it to stay on. Turned out to be 2 bad capacitors that had budging tops. There is a video for that one on my channel.
mine looks gust like the one your working on in this video model number is TC-P50ut50
Great video but may I suggest why not take the lock washers and use them with the old nice magnetic screws and while your in there install lock washers on all the other board mount screws. Thread locker is another option.
The screws came in the kit, an yes I did replace the "ground" screws with lock washer screws, on the ysus board on the left side as well. Not all the screw are ground points but the ones that provide an electrical connection were changed. Locktite is generally not recommend as it fills the gap between the threads an acts like an insulator. That is why washers used. To maintain good electrical bond.
Hello This guy is a top man..enjoy all is videos very good,Helpful....I find Plasma set overheat a lot,some have funs insdie...I use a fan on the side blowing cool air at the back...

No picture on lg is usually the zsus board. I am not familiar with the model number. Does it use the ipm chips on the ysus and zsus boards?

Great video, the exact same screw arched on my ss board as well. I've purchased the kit only to find out that repair shops will not install it for me. Guess I may give it a go on my own. Otherwise, what's the best way to find a guy like yourself that would do the soldering for me?
Its not hard to install this kit.I can understand why shops would not want to install it. They want to be able to pad the bill with a hefty diagnostic charge, and if you go in with parts to install, the guy gets his nose out of joint. I have had threats by others that are feeing their business impacted by free advice. I spent 20 years in the business and if I was still putting food on the table repairing electronics, I would probably be exactly the same way.
I believe I destroyed the connectors for the ic while removing it. I soldered across the pins and heated it up,when I picked it with my tool the pins came up with the ic. Can that be repaired?
Yes the board is repairable. You just need to use some fine wire to repair the lifted traces. Make sure you have a good magnifying glass, and you should be able to see where they went.
+12voltvids thanks a lot for your responses
I'm by far not an expert... but isn't carpet a poor choice of a tabletop for an electrical engineer? Wouldn't ESD be a concern?
No not an issue. Never have had an issue in 35 years.
@@12voltvids Is this because the kind of circuits you work on are more resistant than others or do you think the entire threat of ESD is overblown? Do you employ any strategies against it?

Again I don't need to because what I work on is not overly ESD sensitive.
When I do work on ESD sensitive devices, which would be laser diodes out of the drive, I do use ESD best practices like shorting the short pins before removing it, grounding myself out to earth ground ect, but those are rare instances. Consumer gear is pretty much bulletproof as far as ESD goes and that is what I work on, so no I don't generally need to wear a ground strap because there is no threat. Also I do not wear synthetic clothes that are going to build up a charge. Bare chips and some semi conductors are very sensitive when they are not installed, but once installed even those very sensitive components are relatively safe. This is why the short pads on the laser are shorted prior to disconnecting, and opened only after connection. Because once the laser is unplugged, the flat flex cable will act as an antenna and will easily pick up a chare that is applied across the diode junction will pop it.
@@12voltvids Thanks so much for taking the time to respond. Love your videos, keep it up :)
I have a Panasonic 55", model #TC-P50S2...Flashed red 10 times in sucession..Can you tell me what 10 blinks means?
Missing / shorted stb 15v , sub 9v, sub 5v, BT30V or wrong diagnostic by A board.
My Panasonic model TC-P5out50 Would not turn on I had to repair the board that is in this video. The TV comes on but I have horizontal lines in the picture but the picture is nice and clear Can you help me with this
+lee rossi Horizontal lines are usually problems with the scan drive board (the one on the left side that plugs into the panel buffer board) or the power supply.Check the ground screws first. If these are OK, then you might want to check the large capacitors on the scan drive boards and power supply. Also make sure that all your connectors are properly seated. Won't hurt to reseat all of them.
thank you for this good tutorial sir...
I have a 2010 TC-P58S1 with a 1 blink error code. Have you ever worked with a 1 blink code?
1 blink code points to a communication failure of the "A" board..
I have a question I fixed the 8 blinking problem.. But when I turn on my tv after it powers up I turn it on I hear a little click and no picture on the tv... What could be the problem?
+Manuel Contreras Taken from the troubleshooting guide for the 8 blink code:Abnormality of the sustain drive circuit. Open or loose connection between the SS/SS2 Boards. and FPCs from the panel (SS52 - SS54 - SS55 - SS57). Open or loose connection between connectors C10/C20 or C26/C36. Wrong diagnostic by the A board As you can see 8 blinks is the SS drive circuit. The componets that failed on my set are the most common. You will need to troubleshoot further. It also could be on the y scan drive board, or the buffer boards. This trouble will require troubleshooting with a meter. My diagnostic videos show real world problems I have encountered, but these failures are by no means everything that can go wrong with electronics.
+12voltvids I checked everything you advised .. But basically what's happening now is that I have the 8 blinking light problem(still makes that click noise that powers off the tv) but no 8 blinking flashes... jus tv is on no picture.. :(
+Manuel Contreras
At your power supply voltages correct?
15:46 Why or how would a common ground connection arc? Don’t they inherently have 0 volts across them? That’s really interesting, never heard of that
Because it is not a common ground. They were using the metal chassis to bond all the grounds together.
I didn't know panisonic made those TV's back in the 80s based on that intro
Where does this HDTV was made?
***** Assembled in Mexico
thanks for the vid I'm sure I have the same problem just by inspection. Now if only I was good with sadder 😭
+ArsonKillzEm sadder? Well at least you didn't call it sodder.The SOLDER work is the easy part. This fix is pretty simple, and with the lock washers should last.
+12voltvids haha yeah I looked at it again and face palmed because I spelt it wrong, seems easy enough I just don't have board soldering experience I just don't want to screw up, seems a lot more harder than soldering pipes for work, haha steady hand is needed
+ArsonKillzEm If you send me the board with the parts kit I would be happy to change the parts for you.
+12voltvids that sounds super awesome and would be greatly appreciated , cost is my main concern though
+ArsonKillzEm Shoot me an email from the home page if interested in a quote.
I have the 8 clicks so I replaced the SS Board and it's still doing the same thing so I am lost!! Any suggestions?
You need the troubleshooting guide. There are a few things that can cause the 8 blinks. You have to isolate the board as I did. Also did you buy a brand new board or an Ebay special? I have found that most of the boards being sold on ebay are bad.I have a 55" right now. Have not published the video as the set is not fixed, but the replacement board received was bad, and had a totally different symptom.This is why I troubleshot to component level and ordered in the component kit, ,because I knew I would have a working board afterwards.
Thank you so much for responding! Yes, unfortunately I did get it from Ebay! Ugh
Nice repair!
Where do you get your repair literature and schematics from?
Lots of searching. There have been times I spend 3 or 4 hours looking. The vintage studio are generally easy to find.
@@12voltvids Thank you. Your up late.
Is that the board that the antenna wire hooks in to. I'm not shore.
+lee rossi
No it is on the left side, the buffer board plugs into it. I believe Panasonic call it the SC board. In the video I referred to it as the y sustain.
+12voltvids The boards with the 8 ribbon cables (also called FPC, or flexable PC) is the buffer board(s) Some sets have just 1, and others have an upper and lower. The fact that your set has 8 FPC tells me it is a 720P set, as the 1080 have 10, and the 480 have 6 of them.The scan drive is what the buffer board plugs into. It is the large board next to the buffer boards on the left side looking from the back. In the center is the power supply, and to the right is the common scan board, which is the one that had the component failure on my set.There are many different names depending on the manufacture. Panasonic refer to the boards with totally different names. I have referenced them using the Samsung names, and LG names in the past as those were the most common sets I have worked on.On Panasonic they call the buffer board the SU and SD for scan up and scan down. The SC is the scan drive board, whcich Samsung and LG refer to as the Y sustain.The SS board is on the right, and it affects the entire panel brightness, is called the X main on Samsung, and the Z sus on LG.Horizontal lines in an otherwise good picture are most likely a failure on the SC, or the SS board, perhaps the power supply. Check the capacitors on these boards, an ESR meter is helpful in determining of a capacitor is starting to go bad. Of course if you had the ribbin connectors undone, check them to make sure that they are properly seated.If you check my Samsung buffer board replacement video, part 2, you will see the symptom of an improperly seated connector as the first time I plugged the board in there was an issue that caused thick black lines in the picture.
thank you for this good information...
Do you know where I can get a th-p42gt20z service manual ?
No
Thanks for the reply,I guess the 10 red light flash will be the same on all 2010 models ?
Hi,
An excellent instruction video. I learned a lot. Can you tell me where you got the Panasonic trouble shooting manual from? Also, can you tell me the name brand of the liquid rosin you use? It would be easier for me to find some here in the US.
I never use an electric screwdriver. It's too easy to over torque something or ruin a screw head. An old fashioned slow-turning screwdriver gives me a better feel for the job.
Regards, Tom
THOMMGB The troubleshooting guide can be found here:www.toms-service-manuals.com/getfile.php?mode=viewpdf&req=Panasonic_2012_PDP_Troubleshooting_Guide_ST50_ST_Series_%5BTM%5D.pdf&mfg=PanasonicThe liquid rosin I use is made by MG Chemicals. I agree re the powered screw driver. Never stripped one by hand, or broke something by putting a long screw in a hole designed for a short one.
thanks for the vid how much for the whole board cause i dont have time and tools to do that fine of soldering
+Breanna L.
Sorry I have no idea of the price of the board. I am sure shop Jimmy sells complete boards but I don't know how much. It was probably much more and that is why I ordered the service kit.
Breanna L. www.shopjimmy.com no longer sells the whole board. If you aren't looking to get yours fixed I would buy you ss panel off of you.
The 4 parts are easy to change. Set works great now.
Panasonic Viera 65 inch plasma TV about 8 years old. Starts to click on then fails, then blinks 8 times, pauses and repeats 8 blinks. How likely is this the SS board as suggested by Panasonic?
James Bell
what happens on Panasonic is they neglected to put lock washers on the screws that hold the boards to the chassis. over time thermal expansion of dissimilar metals cause the ground screws to work loose and the TV starts shutting down. eventually it will blow the 4 parts documented in my video that shows the installation of the parts kit to repair the ss board. all the screws need a lock washer and tightening.
Thank you so much. I ordered the ss board off Ebay wanting to avoid all the soldering etc. I will definitely make sure to get the lock washers to avoid them getting loose and arcing again.
Providing that the board you were sold off fleabay is not bad then your problem is solved. Myself as you can see I prefer to replace the components that failed. I did order a replacement buffer board for my Samsung from ShopJimmy, and the first one they sent me was bad, but they promptly replaced it, and that TV has been working perfect ever since. Aside from the crack in the screen, it now has a lovely permanent burn in of the Global TV logo in the bottom corner of the screen as the only channel I watch on that TV is the morning news in my bedroom as I am getting ready for work, and during the news they crank up the logo to 110%. So after 2 years of use, 1 hour per day I can see the logo when I change channels. Doesn't matter though, as the screen has a crack, and I got the set for free. Invested 25.00 to fix it.
Love my Plasma sets. The one I fixed in this video is sitting in a closet awaiting one of the other sets to break, and then it will be put back in service. It was my mother's set, and I traded her a smaller Sony I had because she had to move to a seniors facility and they wouldn't allow plasma. Believe it or not, facility rules, LCD only no bigger than 37"
how bizarre they would ban plasma screens? I have a brother in a convalescent home in Los Angeles and I replaced it TV with a 42 inch plasma. Maybe they have different rules in California. you've got me a little scared regarding that eBay comment. fingers crossed the board works for me . I'll keep you updated. Thanks again for the advice
Why would they ban plasma screens? Power consumption? I call BS on that one. The early ones were power hungry, but the later generation sets were all energy star compliant.
The reason for plasmas demise as far as I can tell was economics. They cost more to make than LCD, and 90% of the population was convinced that LCD was better just due to the shear number of manufactures that flooded the market with them.
do I need to repair the surface of the material where the defective screw mounts.. ie circuit board and frame?
+Jesse Clark
I simply scrap off the carbon on tg frame an re-tinned the board around the screen.
+12voltvids thanks
+12voltvids how do I retin the board? this is my first time doing this..thanks for the help. I broke a connector clip for the top ribbon on the ss board. where can I buy a replacement ?
+Jesse Clark Melt some solder onto the copper trace at the screw hole.I have no idea where you can get the connector. You might have to find a blown board, and get one from that, as they are specific to the model of TV. Be very careful with the with the ribbon cables that come off the panel, as if you damage them, the panel of done.
+12voltvids i damaged the copper wires in the board while removing the 8 pin component..is there any way to repair this or is the board trash?
Uh no, my IC152 now seems to be missing a lead, would love to share a photo will try on my google+
Finally found a cheap enough replacement! If anyone wants the old one that needs a good repair, I got one!
