I have a hp pl4260n and last night my tv made a "pop" then the picture faded to near darkness. I have been reading alot about peoples tvs going blank, mine still has a picture but it take 3 times as long to show up then it is all dark and has a lot of shadowing/ghosting. Is this the same problem that can be fixed with that y sustain board that I am hearing so many great things about?
Thanks
Same thing happened to mine. Pop tonight. No picture now.Same thing happened to mine. Pop tonight. No picture now.

Most common issue is power supply board fails--Plasma sets do not sell single parts--only a complete board---may need a tech or shop to look and determine what is wrong.
I can suggest things but need to know your skill levels--this is not for everyone....
Either X,Y, or Z-boards seem to have developed a problem, when this happens it results in a 'sound-no-picture' condition. If its under warranty take it back, if not have your local tv repair center fix it for you....
Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman
