Greetings,

I have a VIZIO 42" television, model E420VO.

When I turn on the set it powers on, shows the VIZIO logo on the screen and then shuts itself off again. It is on for about 2 seconds.

I know these TVS are plagued with problems. I have the television apart, there is nothing obviously wrong with either board. Anyone have a similar problem? Any idea where to start?

P.S.

New to the forum, thanks for all of the helpful information so far.
