I found this write-up very useful! We had the same issues this week.
One day TV fine, next day nothing. I followed everything I could find online and then called Vizio and asked for help. I got nothing from them. I also go this comment: "sir, did you get the extended warranty?" i replied that i didn't "Sir, that is what extended warranties are for" I said, extended warranties allow companies to take even more money away from us.
Yes, I understand that things don't last forever, however, they should last more than 2 years when they cost $600. We purchased our TV about 18-24 months ago so we are out of the 1 year warranty period. Vizio offered to fix our TV for $400, which i passed on and stated i will never buy another Vizio again.
Vizio is not taking responsibility here and should as it seems like a widespread problem. I have it working again after following your repro steps, let's hope it says running for a while longer.
Product or Service Mentioned: Vizio M502i-b1 Tv.
Reason of review: Damaged or defective.
Monetary Loss: $600.
Preferred solution: A TV that works like it should. I want my TV replaced..
