Gateway 42'' Plasma - Dead? How to fix?

We've had this for 6 years. Within the last 6 months or so, we'll be watching and the screen will go black and we cannot power it off. In the past it's been resolved by unplugging it, letting it sit for 1/2 hour, and then plugging back in and that has worked to reset it. However... now the reset isn't working and we cannot get a picture at all. We don't even get the mode in the top corner (TV, DVI, Component 1, etc.)
The other strange thing is that when we hit the power button to turn it off, it doesn't power down but instead changes the input (TV, DVI, Component 1, etc.)
Please help!!

There is a problem with cracked solder on the y sustain power lead leading to the y sustain board. You can fix it if you are handy with soldering. 4 out of 5 pins on mine had cracked solder allowing arching.

Very light colored verticle (1" wide) ribbon on LG 42" Plasma TV


The TV is design for 16:9 format. The bars appear when the TV off showing that the TV has been watching under channels which is have 4:3 format for long time. The screen was burn out because no sweepping to those area. This is not critical problem but you can do nothing to fix it. To eliminate it a bit you shoud read the manual, I believe it has mentioned how to roll or sweep the screen. For plasma TV, if you keep watching 4:3 channels fomat, you shoud do it one a month within 30'. Good luck

its a bit complicated but you trace the circuts and voltages across schematic,, with the if you can find gateway service manual for your specific tv besides this these things are very touchy they have built in circut protection and its just a matter of finding the fualty circut or ps led flash codes.. hope this helps..
