My Vizio VF-550XVT1A shows no picture, just a black screen, the logo lights up white and amber on the bottom when on standby, what do you think could be the issue? I can answer any questions/post pictures if needed
what inputs are you trying? if you go to the "TV" input, does it show "snow"?
Nothing, it is completely black.
As I have seen with a similar LCD tv, she replaced all the parts but when the main board was replaced, that fixed the black screen issue which is similar to mine. Should I go by this? or How can I test the main board?
