Re: Panasonic tc-p42s30 TNPA5349 SN board
Finally got it working - removed all the blown up Chinese components and scrapped a spare x-sus from a TX-P50ST30B, which yielded the IGBTs I needed to fix it.
I fitted RJP30H2s in place of the DG302s as the 4 x DG302s I removed from the scrapper also tested as capacitors. I'm not sure if they are dead or my transistor tester is telling lies about them.
My Chinese supplier e-best_trade has been good for supplying the dual driver transistors and the buffer chips but the FGD4536s I bought were clearly not up to the job and must be fakes.
Re-fitting all the screen ribbons took about 6 attempts before I got a picture free of horizontal lines but it looks good now.
Another high usage set that shows 32,000+ hours before the loose screws took out the y-sus so pretty good. Picture is still as sharp as ever, even with my salvage parts repair
