Last night when I come home after work, turn TV on is working again & let run on Fox TV chanel + HDMI from Blueray player about 6 hours is work final. Will check another source late

Find the service manual

Look like my TV had MAIN BOARD parts# BN94-01723A or BN97-02449A is bad (I think the PC input area at mainboard had some bad components, because when I plug PC to TV the will shut down & can't turn on again. Had unplug TV about 2 hours or more to reset)
when I take a look on service manual at PC input section at mainboard maybe some electronic components bad or leaked to ground
I will check late
