Re: Vizio M65-C1 won't power on

Question for the OP:

How did the youtube steps work but not replacing the power supply? Did you fix the power supply with the newer main board or your original?

I ask because I have the same set that turns on, but only to display the Vizio logo for a few seconds. The backlights stay on inside the set for about 30 seconds then off for 7 and it goes like that over and over. It used to startup after doing this for 30-40 minutes but now won't.

I found the same video and opened my set. My issues didn't seem to follow...
