Model: P56940
Chassis: PTK195E2P
Service #: P56904YX2

The TV occasionally turns itself on and sometimes won't turn off. When in use, it works for a few minutes and then starts turning itself off after a few seconds, even after it's turned back on. Then all of the buttons stop working. The power button does nothing, and all other buttons cause the television to power off. Once this starts, it will no longer turn back on. Unplugging and plugging back in will allow it to be turned back on.

It's been turning itself on for a while, but the other things started happening more recently. It also sometimes makes a high-pitched squeal that I can barely hear, but it's agonizing for my girl-friend. I opened it up and cleaned out the dust, but I didn't really expect that to fix it anyway. I'm just not sure how to find where the problem is.

I'd suspect the front button panel. check that those switches arent shorted.

When I disassembled the TV to clean it I plugged it in to test, and it turned itself on with the button board disconnected.

Say what you will about plugging it in while it's taken apart, but I'm pretty sure it's not the button panel.
