i have a TV that comes on just fine, then after about 5 -10 minutes will shut off. After the TV sits for several hours or a day or so, it will come on just fine again, then after a few minutes just shut off again. When it shuts off, pressing the remote ON/OFF or the ON/OFF button on the TV itself does nothing, you have to wait. I can also hear buzzing/humming noises from both boards on each end.
Random info:
clicking: only one click when i power the TV on and one click when it shuts off.
The red LED at bottom left stays on. The red LED on the video board stays on.
The green LED on the control board? (small board under power supply) blinks, looks like a pattern to it.
I looked for visual signs of bad capacitors, specifically the C802. didnt notice any.
The TV belongs to my inlaws and i really don't have much time to troubleshoot. If it sounds like a power supply issue, we can go ahead and just order one and be done with it.
