My 50pc55 tv worked fine until recently when I turned the set on and had the green power light on but no display. Plugged in an av input and sound works perfectly too. Replaced the y-sustain and buffers, but there was no change. If I leave the tv on for a while then turn it off and on again I get sound and the display just shows a pink and green fuzz. Examined the set again and the PSU board has several blown and leaking capacitors that inevitably make a sizzling noise when on. Question is could these caps be causing the tv to power up but have no display / occasional fuzzy display?
Quite possible-----replace all bad ones and also if possible the voltages coming out of that board need to be tested---to be honest other than the caps it sounds like a main board issue. The set may have been run too long with the bad caps.

After all the research I found out that the IC on the Z board is bad and new board was ordered and replaced. The plasma work fine after that and picture is excellent with the new board. This forum is great, without this I couldn't fix it myself. Thank you.
