I've had a similar experience. After ruining a Y-Sus, I now always power down plasma TVs before changing connections. Also, the Y-Sus boards sometimes hold charges for a while after the main power is disconnected. So, I monitor voltages at the connectors and discharge caps on the Y-Sus before proceeding.
My 42 LG plasma 3D model code 42PW450-TA. Symptoms.stndby light ON..but unable to turn on the TV.when push the ON button seems like going to ON but return to stdby mode.any sugesstion
I suspect there is likely a short on a board other than the power supply, but i have no specifics other than what I show in some of my other videos which can be found at www.tvrepairinfo.com/
The school of hard knocks is a tough but one really takes lessons learned there to heart. I've always thought mistakes are good teachers, I just try to not repeat them.
I wish you were in my area. We have no one who will repair plasma TVs in the Dallas metroplex. I have a Panasonic TC-P50UT-50 plasma that has no power, no stand by, nothing. I had a cable box, which was connected via HDMI, short out and after that my Pani has no power. Would my main culprit possibly be a blown fuse on my power supply? How can I check to see what's dead? Any help would be GREATLY appreciated. I miss my TV.
Do you have any experience with an LG model 50PJ350 Plasma? Got one in with 7 different mosfet transistors on the Y-Sustain board dead shorted. Replaced all 7, powered it up, and, well I should have saved it for the 4th of July lol. New parts went off like a string of firecrackers. So I'm wondering if something in the panel or on another board can blow up the Y-Sustain board, or if I most likely missed a bad component? No more obvious shorts but there are several control IC's that can't be checked with a simple ohm meter. Bottom line, would it be worth $75 plus shipping to try a whole different Y-Sus board, or is it likely something in the TV would blow it up too?
A friend of mine has a 42" Sanyo Plasma TV. He has his XBOX plugged into an HDMI port. Every once in a while the TV Will turn off and the Xbox will reboot and then the tv will turn back on and put out this really high pitched squeal. It doesn't do it all the time, it does it most on the xbox input, but will occasionally do the same thing on the DVD HDMI input as well. We have never noticed it doing it on the Composite input. Just wondering if you've ever heard of this?
We have a 2009 Pioneer PDP-5090HD. Last night when it was turned on it presented with a caution sign and the words "plasma display". The power light flickered and turned off. Thank you for your help.
Good point!! I service commercial fire alarm systems. I was to lazy to walk to the electric room to turn of the main power. I removed a 10 pin ribbon cable from the CPU. Lets just say, this customer has a brand new CPU. Filled out a service ticket. NO CHARGE!!!
I have a Panasonic plasma TV model TC-P42C2. it does not power on and the red light blinks 7 times... I believe it's the Y Sustain board am I correct and what would the cost to replace it be??? thanks in advance
My Samsung PN50B850 has a problem, after it gets warm (30 minutes watching) the menus start going crazy and it goes in store mode or start switching channels like crazy. If I lower the brightness is stays cooler and it lasts much longer before doing it. Do you think it's the tactile buttons board that may be faulty?
Help/Ideas? Model: Sony KDE-42XS955 Type: Plasma Size: 42 inch Manufactured: 2005 Retail: $4,995 I bought my Sony KDE-42XS955 from B&H Audio Video in Manhattan for $4,450 in July of 2005. It was the absolute finest TV on the market at that time. It never gave me any problems during its 11-year-long life. It finally died in March of 2016. It was still producing a perfect picture up until it simply refused to power on. When it would power on, only audio was working. The video went from perfect to nothing. There was never and fading of its quality over time. This leads me to suspect there's some internal power supply issue, or something that has nothing to do with the TV's ability to produce an image. Because again, the image was always perfect up until it died. I wonder if this TV can be fixed? It was the greatest TV I'd ever owned, and I've had many since this one. Today's average market range TVs still aren't as good as this set. This is why buying the finest TV you can pays off. You future-proof yourself for at least a while. Again, except for the highest-end sets, my 2005 Sony plasma was better quality than 95% of the TVs made in 2018. Any ideas? Thank you for your time. -Mick O'Brien
Panasonic TC-54PS41 seven flash code. Both sides of P2 on the power supply board short.Going on to TNPA4844 board and disconnected SC41,SC42, & SC46. And check on SC2(connected to P2) I still get a short. Take it the board is bad any suggestions on where to go from there?
One question, once the ribbons are correctly connected, and no visible lines, is the Panasonic TXNSN1RHUU (TNPA5593) SN Board suppose to make a humming sound?
Holy Cow. i am not even a TV tech, just a all around fix it man really, i do admit to having over 21 years in the car audio field and I can and do repairs on old school car audio that is WORTH it, and I also have been building custom computer towers and lap tops for 19 years. but I have never, not even as a rookie kid, thought that it would be OK to disconnect or re connect any wire, connection, ribbon or anything that requires power. YIKES! lol I guess it's a good video but WOW. Oh yeah, with these kinds of things that have capacitors and have only recently been disconnected from power, sometimes the stored power in the caps can cause this same problem. best not to mess with it till you have the power dissipated. for instance, people have been sent to the hospital from reaching into the back of a unplugged microwave oven. thats a load of power. it doesn't take much to fry a ribbon cable.
Hello there, I bought some of your products and the quality is exceptional, I have a plasma, Zenith P42W46X, it is giving me 4 rectangular flashes, one to the next one, vertically, going up and down, with a withish blurry image, after I press the input button it only give me a blurry whitish screen, check caps they seem to be ok, any idea please...?

I've had this model (TC-P42X5) for almost 3 years, and now the sound is randomly chirping, popping. clicking or blasting white noise. I does this while running off satellite or an antenna, and only does it once in awhile, thankfully. Picture works fine. Any repair suggestions?
Hi, Thank you so much for sharing your knowledge. Your videos are so informative and easy to understand. Recently I acquired an old Samsung ps42c7s with a bad y-sustain-buffer board - 2 of the IC's are cooked. On close inspection I also noticed that one of the buffer board ribbon cables has a slight tear across it through several of the thin "etched wires". I believe these cables are fused to the panel & cannot be replaced, but is there any way that such a tear can be repaired?. Thanks.
Hi. I have Samsung plasma 42". Power board have input voltage of 250v, but something is happened and I no any different voltages are there no Va,Vs ,5v and 15v what can be damaged? No short as well, power board is disconnected from any other boards. Before vas short on x buffer and , as far I found in x main blown fuse, all replaced, tv has sound,when on, but no picture.found that no power going from power board.
My friend is having an issue with a couple of very narrow green lines running down the center of his display. The problem is hardly noticeable most of the time but he is worried that it will worsen with time. I was wondering what you would suspect could be the issue and if it is even worth attempting to repair. Thank you for taking the time to read my comment.
I have an LG 50PC1DRA. The fan had been loud a couple months. It was working fine and I shut it off for the night, and the next morning there were colored vertical lines completely across the screen. It looked like you could barely make out a picture. Any advice would help. Thanks
+Karen Fitzgerald If your fan failed to cool things off it may have caused one of your ICs to fail, but I don't have any specifics as to what the symptom means.
I sadly did this exact same thing after replacing my SN board (SC, SU, SD all in one board). What exactly happened to your Y-Sustain board in your case? Was it fixable? Did one or more components short out on the board? Was it a blown Driver IC? Please let me know. Thanks.
HPS4273X/XAA Started out that when I would be watching tv or dvd a blue fuzz would come over the tv. Shut it off for awhile and the fuzz would be gone for awhile. Then there may have been vertical lines and black bars on the screen or even only half a picture, but I don't remember because the tv now turns and has audio but no picture and it happened a long time ago. Recently I have renewed my interest in repairing this 42" tv.
I don't believe the current is high enough to be much of a safety issue, but yes arching is definitely something to be concerned about with electronic circuits which have semiconductors.
Yes, but what damage did re-seating the connectors do to the board? Is it because a couple of pins shorted, or because voltages were fed back on the wrong pins? Or what? Aren't you curious as to what mechanism caused the failure and what it did? I am.
Yes it did make me wonder about the cause. I can guess and say it may have been a DC arc from one of the coils being abruptly disconnected while the power was applied, , or perhaps a load imbalance across an IC due to not having a load on the output of my power supply.
I just replaced the power board on a dell w4201c hd plazma and now it works for a bit and on random flickers and white kinda goes pixelly and colored if I shut tv off and power back on it goes away for random time then comes back.. It was doing it for a sec or two and when it was you could here a buzzing kinda sound and then it would correct itself now when it does it it will just get worse and worse until I restart tv right now it is flickering now going ghosty looking,, I turned it off and back on now it looks ok to gf but to me it looks like it has kinda a hard to see flicker like if you record a tv like the refresh rate is screwy please help can record a small video if it would help
I've never heard of a horizontal board, but if you have the part number of the board you're looking for, you might want to see if it's available through shop jimmy. www.shopjimmy.com/
got a TCP42S30 - had 8 blinks - replaced SS bd - no blinks - steady led - no sound - no video - short across SC power plug - having trouble finding replacement - typically what fails here - cap?
Does anyone know why you have to wait 3 days after unplugging a Panasonic plasma TC-P42X1 TV before it works again? The power supply has been replaced and it's still doing it. Cheers.
I have the exact same one. It's been 4 years now, if you haven't already junked it then you should count the blinks. It will blink a number of times, pause, and blink again. Count the number and it'll tell you what's wrong.
Interesting to see these newer Panny X50/X5 plasmas failing. They are Panasonic's budget 720p model so there are lots of cost compromises. And Aishi caps, ugh.
I guess no one likes to look human. LOL. Someone just called to say he wished he had seen this video one day sooner.He made the same mistake on an LCD TV and damaged a board.
HI,can any of you gentlemen help me,i have a panasonic viera tc-p46x3 when i press the power button nothing happen,tv does not turn on,no lights at all tv is only 2yrs old any ideas or suggestions on this issue?
Maybe it is a blown capacitor? quite common and usually causes no power or a click. The only way to find out is to take the back off and look for capacitors with bulged tops on them. hope this helps.
This has happend to me before too. once i was pulling off a high voltage connector and it arched to the metal case from about 3 inches away. you can say i jumped a little bit.
I have a Panasonic Plasma tv it is about 10 years old it has magenta pixels that some times show words on the screen they don' seem to stay in the same spot they move
+Debra Van der Lee sounds to me like that low voltage problem that folks are having. if the words are telling you to do awful things though, it;s more than likely possessed or you might need a lil different kind of help. LOL Just kidding. That is weird though, I have heard of STARS, sparkles, odd color blotches and the most common bar from top to bottom or side to side. It;s possible you have burn in issues, sometimes if some one in your house likes to watch sports or a programs with Bright banners and tickers running on the screen, football or whatever, things that stay in the same place on the screen and run for a long time, when you shut it off you can still see where those things are. also when the next user comes along to watch something else BAM they can see the things that were on the previous viewers screen! the problems will get lighter and lighter as you watch the NEW thing and then should go away completely until that other viewer does it to you again. video games will do this as well. if niter of those things are it. beats me. I hate it when i cannot figure something out like that though.
… had burned a chip on a x-sys (I think) board from a sony plasma TV, forgot to plug in a small plug on another board, actually it was hidden behind other cables... well....magic smoke came out....
Yes the capacitors can be replaced, and if your lucky doing so may fix the problem, but keep in mind there may be other problems besides bad capacitors.
Electronics don't know about territories. If you're dumb or not knowledgeable to turn off the device, this stuff happens. That board runs at 60 to 180v, anything can happen, electric arches, shorts between pins on those strips of connectors...
High voltage inside televisions.... Never a good idea to be randomly messing with live high voltage cables. If you have to take live readings, you shouldn't unless you know proper safety, which would already include not ever doing that...
Humility is a wonderful attribute to see.
Thanks for the valuable caution.
Thanks for admitting a mistake, warning others and hopefully saving others from this kind of mistake. Not many will admit these kind of things.

I have a Panasonic Plasma tv it is about 10 years old it has magenta pixels that some times show words on the screen they don' seem to stay in the same spot they move
Debra Van der Lee I just wanted to know why I guess no one knows see ya
+Debra Van der Lee sounds to me like that low voltage problem that folks are having. if the words are telling you to do awful things though, it;s more than likely possessed or you might need a lil different kind of help. LOL Just kidding. That is weird though, I have heard of STARS, sparkles, odd color blotches and the most common bar from top to bottom or side to side. It;s possible you have burn in issues, sometimes if some one in your house likes to watch sports or a programs with Bright banners and tickers running on the screen, football or whatever, things that stay in the same place on the screen and run for a long time, when you shut it off you can still see where those things are. also when the next user comes along to watch something else BAM they can see the things that were on the previous viewers screen! the problems will get lighter and lighter as you watch the NEW thing and then should go away completely until that other viewer does it to you again. video games will do this as well.
if niter of those things are it. beats me. I hate it when i cannot figure something out like that though.
i have an lg 60pk200 and it has a vertical green line in the center of the screen. anybody know what causes this?
… had burned a chip on a x-sys (I think) board from a sony plasma TV, forgot to plug in a small plug on another board, actually it was hidden behind other cables... well....magic smoke came out....
I have never repaired one myself, so I don't have much to suggest.
I have bulging capacitors on my y sus board. Can those be replaced or do I need a whole new y sus board??
Yes the capacitors can be replaced, and if your lucky doing so may fix the problem, but keep in mind there may be other problems besides bad capacitors.
Thanks! And now comes the hard part, trying to find the proper replacements. I'm a rookie at this
If you call digikey and ask for help they can get one of there engineers to help you order.
Philips no power but a loud buzz
i made that error and tv doesnt work againe how to solve that please
how much did it cost you to get the boards repaired?
Thank you
The TV shown in this video was my own, and I decided not to bother repairing it after my mistake.
Thank you,, Some times i do that
Well duh. I remember firing a guy that worked for me for doing just that, because I was the one eating the cost of the repair.
my son kick the TV and glass in broken in side any help
Once the glass brakes the TV isn't worth the money to repair it in most cases.
If hitting the TV helps this suggests there may be an intermittent solder connection. If you watch all my videos you may get more ideas.
Thank you!
Electronics don't know about territories. If you're dumb or not knowledgeable to turn off the device, this stuff happens. That board runs at 60 to 180v, anything can happen, electric arches, shorts between pins on those strips of connectors...
Why is the video wavy?
thats a shame was the board expensive
I would guess it was probably due to an arc.
I have a 55 Samsung smart tv crated screen
Thanks.
of course always put the power off with everything
High voltage inside televisions.... Never a good idea to be randomly messing with live high voltage cables. If you have to take live readings, you shouldn't unless you know proper safety, which would already include not ever doing that...
may the invertor is damage
tanks u have my bottom
not taking the power off before meddling with the connectors are just stupid procedure
No kidding.
Who has a old tv I have a smart tv
Confuse
I learned too late 😭
