so i got this tv to fix and the guy says it turns off and on over and over again.
i was able to see this behavior after running it for a couple of hours. at first it seemed fine. i did notice in the lower left of the screen though, there is an area that is not as brightly lit, indicative of possibly some LED issues...its only really noticible on a white screen though. during a regular movie you hardly can tell.
feeling on the back of the tv, i dont notice either of the boards getting very hot, but it seems like a heating issue since it takes 2 hours to fail...
once its in "fail mode" and turning off and on, what should i look for to tell me if its the main board, or the PSU...or could it actually be bad LED's would that cause the tv to shut off? i know some tvs keep running and you hear the sound and can even see the image with a flashlight, but do some tv's just completely turn off if the backlight goes out?
