I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

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.

The solution is you have to buy a new better tv with a good extended warranty in payments. JZ

Bypass the SEINE module if you know how. If you use off air HD you will have to get a new module.
