Panasonic TH-42PZ8E Plasma 7 blinks problem.

[Mark81]

Hey folks,

I have an old 2008 Panasonic TH-42PZ8E Plasma that has the 7 blinks problem after a lightning strike nearby a few years ago. At the time of the strike it was in standby mode.
It has been send for repair before, but the problem came back after a week or so. Back then the mainboard has been replaced.
But here comes the weird part. After turning the tv on and off for a couple of times suddenly the tv stays on and everything is normal. I can watch for hours no problems at all. It is a very annoying problem so i bought another plasma tv for main use and this one moved to the man cave
Last week i saw someone on youtube fixing this problem and i thought hey why not trying to fix mine.
I have been searching for answers for this problem for a while now and i have never seen a case that someone has been able to get it working after turning it off and on a couple of times.
Shall i follow instructions on this technical manual i found (from another model)?

I already took the back panel of.

Many thanks in advance,
Mark

Yes i did, but since this is about the 10 blinks i thought it was not the solution for my problem

It was interesting to see that the capacitors were reported as being a common problem with the set. Would be worth checking.

Bunk replacement... Ebay? if so then chances of receiving a bunk parts is very very high.... It's most likely SC aka Ymain

Do you have a D board? if so check it. But most likely the fets are bad or at least one is on SC board. Once you pinpoint which one replace it and update firmware.

Yes they are ebay 2nd hand parts.

I think there is a D board behind the A board. could a bad D board also give the 7 blink error?

Re: Panasonic TH-42PZ8E Plasma 7 blinks problem.

Wow, i somehow fixed it by removing and reinstalling the A board.
Maybe a loose contact or reset somehow??

7 blinks are gone! My Plasma is fixed 8)
