I would return it, sounds like the bulb died.

These types of problems are allways hard to diagnose.. If you were to power on the set and preform tests, you would think that everything was fine until the moment it shuts off.

Look on the main power board and see if you cant find the thyristor (thermal switch), those are the things that when heated will cause the set to power off for safety reasons.. They are normally placed where ever a large heatsink is. That may give you a location as to the problem and you can put a meter around its 2 pins with the set off and unplugged a couple of min after failure, if its short (0 ohms) thats not the problem, if its open, it triggered the event.

Second, you can run the set for a while and check the voltages and Ve, Va, VCC, Vsetup etc and compair to the markings on the plasma PDP sticker. If you see one is falling down over time (volts will be lost as heat) then you can isolate that portion of the supply.

Third and allways the best way to go about these problems is buy a thermal gun and moniter various spots for heat.

Its just vary hard to say, resistance could be off somewhere, diodes could be overheating as well as fets and caps. Thats why a good thermal gun can point you to exactly where the problem is.

Hope this info helps, but I would suspect the problem is on the main power supply itself and not the y sus and z sus boards side boards.

Three suggestions:
Contact http://www.ptscorp.com/television.html. They have a selection of replacement boards or will repair it Fees are usually $50 to $125 and I have had great success with them.
Another would be to try www.shopjimmy.com and lastly do a Google search, if you know the exact part number, to find other sources for the board.

I had same thing happen recently on same model. Turned it on one night, light came on in screen, briefly saw info bar at top, then nothing. Cannot get picture, volume or menu. Each time I turn off and turn on the same thing.
Any solution to this appreciated.

Check your resolution output from laptop it maybe set to high for the TV to handle, also go to the Display Properties and ensure that the second monitor out is enable. Good luck!!
