Re: Vizio E550i-a0 no turning on

I also have a Vizio E550i-A0 that will not power on. I obtained the same test meter readings as louis in the previous posts. I ordered a new power board and installed it today. TV does not power on at all.

Any suggestions on what to check next?

I don't really want to keep throwing parts at it until its fixed.

Is there anywhere to obtain Vizio test information for this specific model? ie pin 1= x V, etc. I have thoroughly examined both sides of all boards for any evident popped caps, etc and find no...
