I have opened the back and did not see any popped capacitors; five have a black dot looking like a dot was placed with a marker pen but the caps themselves are not bulging. There are five ceramic fuses, all of which tested fine with an ohmmeter allowing current to pass through.
The capacitors seem to have gone bad if they have like a black dot on them it is a sign they have actually blown they can be replaced by placing new ones on but it would be better if the board was replaced (unless you wish to replace those capacitors please please do be careful in doing so they hold enough charge to give you a bad zap even kill if one isnt careful)
SOURCE: ESA 42" plasma tv not turning on
I have a 42 inch plasma and I was watching tv last night on it and suddenly it turned off on it's own. I tried turning it off and on and nothing happened. Then I tried to unplug it and replug it and nothing. My remote does not work either. Anyone know what exactly happened? Did my screen blow or what? I hardly ever use the tv and I only had it on from 8:30 p.m. - 10:20 p.m. and it turned off. All the other tv's in my house worked fine - I checked them. Also, my dvd player and cable box is on the same power cord and both of them work. Any solutions or help would be most appreciated!!! Does it just need to cool down or did I burn something out? Help!!!

I had the same issues and the tech came out and replaced the main board... one way to tedt if it is the PDP is in the service menu.. run the plasam ttests and verify you don't see any dots. After replacement the tech checked all voltages and all is well.

Check to see if you get Va and Vs voltages from the power supply. There should be some wires running to the y-sus. A couple of those wires will be labeled va and vs. Are they present? There will be a sticker stuck to the panel somewhere telling you what they should be.

I suspect that your supply has gone bad. You will need to find the service manual for voltage measurements. If you want to get replacement boards many can be found on ebay or you can check www.shopjimmy.com they stock boards for many units and I have had no problems.
