I have an LG TV (70uh6350ub) that shut off by itself one day (no video or sound). I turned it back on & it stayed on for about 10 min. then shut off again. Turned is back on & it shut off after about 3 seconds. Since then, if I leave the set unplugged over night it will come on (video & sound) for about 2 to 5 min., then shut off (although the backlight stays on for several sec, to about 1 min.). After that, if turned on, it will shut off in about 2 sec., or not turn on at all.
Took the back off & noticed that the green led on the power board flashes 5 times (continues doing so) once the TV shuts itself off.
I have the service manual, however it shows a power board different from the one I have ( EAY63749303). Therefore the pin out designations are likely very different.
Any help or suggestions? All this started about 1 week out of warranty.
