Can turn on TV picture with remote but will turn itself off in few minutes. Would eventually stay on after several tries but will now turn itself off every time.
Just from personal exp the easiest thing to do may fix or at least make it better. if u see puffed and leaky caps on power supply replace capacitors. if really dusty clean. both previously mentioned and both helped me. my tv was completely dead and replacing caps got it to power back up and work. it takes two trys to come on but works great so far. then i cleaned every nook and cranny with a small vacuum hose and different size/angle brushes that could be attached to hose. i only took out the psb board with caps and didnt touch anything in there that i could mess up. just cleaning helped enhance the colors. right now this is the best picture ive had on a tv and it was completly dead when i got it.

i have a 56DR650 and it does them same thing. It is still under warranty but where i bought it, they said they can no longer fix it so they are giving my money back. the problem has to do with the color wheel inside.

Try replacing the ballast next. Its the small circuit board directly underneath the lamp housing. You can access it through the lamp door. If the ballast is overheating or has a leaking capacitor, the tv won't stay lit for more than a minute or two.

I had the same issue but instead of shorting out the sensor, I removed the bulb assembly, cleaned the interior of the assembly and TV the best that I could with a vaccum and small paint brush. Once cleaned, I reinstalled the bulb assembly and the TV has worked for the last eight months with no problem.

HI, this may be a simple cooling issue. try inspecting the cooling fans that are located near the power sector. if these cooling devices are not operational, they will cause the power board to shut down periodically, due to heat build up.
If the fans are operational, this will confirm a weak and defective power power board.
