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?

I had a similar problem with my P55-C1 (audio, no picture). I used a flashlight and discovered that the picture was actually working but the backlights weren’t coming on. I replaced the LED driver boards (four of them) and now I have a working picture again.
