VIZIO XVT553SV: orange light logo only

[dotcalminc]

Hi. I have this Vizio that I already tried changing the power board on, but got the same result. Outside of that, I'm not where to go. The TV, when plugged in, only gives me a orange VIZIO light. Does not turn on by button or remote. Any help on this is much appreciated. I'd love to get this working again.

Probably no PSON, which comes from the main board.

Thanks CapLeaker, is this a part that can be replaced on the mainboard or do I need to get another main board altogether?

I see three white smd fuses on the main board that can be checked(near the connectors). Vizio also have problems with faulty voltage regulators.

See this post from budm for regulator testing info:
