So my son tossed a bouncy ball at our ST50, not hard, and the TV turned off. Now it won't turn back on. If I hold the power button down a bit then let go, I hear the "click" of turning on, then like 3 seconds later I hear the click again and it's off.

Same thing happens if I unplug it and plug it back in.

Any ideas?

EDIT:

After some more investigation, I realized I had a piece of tape over the red power light on the front, and the tv is actually turning on, and I can see the light respond to remote commands. However, there is no pictures or anything. The light blinks 7 times and then stops. Then it keeps doing that over and over, but it does respond to remote like you can see the light blink when I press volume, etc.

Never installed the replacement capacitor, although I *did* buy it. Just didn't think I could solder it in without bridging the contact points.

Haven't had any issues since, and TV is used a LOT!! TV is now 8.5 years old.
FIVE YEARS RUNNING now, and no problems with the plasma running *without* the bad *very tiny* capacitor. So I had just removed the one bad capacitor on the fingernail-sized board, and the other "twin" fingernail-sized board continues to run with the original capacitor still there ... without any problems. I thought by now I would've had to open it up again and remove the same *very tiny* capacitor on the 2nd fingernail-sized board...

John,

Post #2481 : how’s your Panasonic plasma after taking out that capacitor (3 years ago)? Is it still running? Mine’s going on 5 years now without the MC201 capacitor, and the unit is approaching 10 years old total.

But I ran my 27” CRT JVC from Jan 1995 to 2015 every day ... so that’s 20 years ($450 new). This Panasonic plasma was $1200 new and only 10 years now. But at least it’s still working!

Looks like this thread has petered out! The last couple of years (2017 and 2018) far fewer posts. People must’ve given up on these plasmas?

Got two blinking reds on my 65VT60. Clicks to turn on, then shuts off and two blinkers.

According to the ST 50 series troubleshooting guide it's missing the P15V from the P board. It's either not being generated by the P board or the A board made the wrong diagnostic. They say the P is the #1 suspect and the A is the #2 . The P board is the power supply right in the middle and the A board is the one with the jacks.

I think it's time to replace. I know the fix can be cheap, but I think I'm going to replace it.

One of the very few VT60's I've seen being a blinker. Model has been very reliable. Make sure it goes to a good home because I agree. Most likely P-board which is good because it's not that expensive. A-Board is the most costly.

It's available to anyone in the Chicago area who wants to come and get it. Not shipping it anywhere.

hi,
hope it's fine i post here.

got TH-P58v10M.

3 weeks ago it sounded a nice pop explosion and died, giving 7 blink code.

looking in it, some transistors exploded on the SC board.

ordered & installed replacement SC + SU + SD boards.

turned on the t.v it worked for 30 seconds and turned off, giving the 6 blink code.

disconnected the SS board and turned it on, t.v stays on, green led, black screen.

does replacing SS board will do it ? or it can be the A board or P board as well?

thank you in advance for any insight.

Still rocking my 65vt60 since day 1.

I did replace a board about 5 years ago (13 blinks of death IIRC) but still running strong.

Hi guys, I need some help... my ZT60 was working perfectly this morning, when I finished watching I turn it off as usual. Later when I tried to turn it on again I hear the relay noise (click) as usual but the tv doesn’t turn on and the red light is blinking, 2 red flashing every a few seconds. Any idea what could be the issue?

Thank you!

My first post in a great while!

I found a great 2012 TC-P55VT50 in our electronic recycling place and brought it home.

It has the 7 blinks of death.

I think I've isolated the problem to the SC board, but was hoping someone has a link to this particular models troubleshooting guide. I've found similar guides, but want to be sure I've followed the proper procedures before I start buying replacement boards.

Can anyone assist?

Hoping people still paying attention to this thread...

I have a Panasonic TC-P65VT50. It has worked like a champ for just shy of 7 years. A few days ago it started doing something that appears to be pretty unique, at least unique in the few forums I’ve found on-line. Admittedly, I haven’t read all 88 pages of this topic, but I’ve perused quite a bit of it.

When I turn the TV on, it works. If it gets past the 3 to 10 minute mark, it’ll work for as long as I want to watch. However, more often than not, in that 3 to 10 minute timeframe, the screen will suddenly display what can best be described as colorized white noise, and the sound goes out. It will stay in that mode for 30-60 seconds, then one of three things will happen. It will shut itself off. Or, it will shut itself off, power back on, and resume displaying the colorized white noise. Or, it will display the message, “An error has been detected and recovered,” it will reset itself and start showing content properly again. If it resumes showing content normally again, the 3 to 10 minute timer kicks back in. If it gets past that timeframe, It’ll work great for the rest of that session. But normally, it if goes all white noisey again… it’s done. One time it reset itself twice, then continued working properly.

While poking around trying to research this issue, I’ve found a number of troubleshooting guides related to 7, 11, 13, blinking error codes. I’m very willing to troubleshoot, and then hopefully send a board out for repair… but with the issue being intermittent, none of the guides I’ve found seem to apply. So I’m kind of hoping one of you more experienced folk will have a guess about the component most likely to be the culprit in this situation.

Any suggestions?

Tom
