must power cycle to get pix
VIZIO P702ui-B3 If off for more than a few hours the led (lower left corner) lights, Audio works, but no picture. If power cycled 2 or 3 time it turns on normally.
This happens with the remote or the manual switch on the set.
I’m thinking about replacing the power supply. Could that fix it or perhaps the Tcon board?
Is this a good question?
