I will give this a shot! I will let you know what I find.

Does it help to know cooling the back of the TV on the left side, with the case on, keeps the TV running? The fan points at the location of the ymain board....

Samsung plasma will work from cold start for 30 to 60 minutes. Eventually the picture will go dark, but sound and remote will still work. If I unplug and plug back in it will continue to work for a few minutes then blank the screen.

I did take the back panel off to look at the caps. All seem fine. The main logic board shows a blinking green light every second when the TV is normal. Once the screen blanks and I try to power cycle the TV the main board blinks once every 5 seconds.

Other oddities with this TV. The panel gets very warm on the back left side when in use....
