Power ON, VIZIO TV SV320 series Screen barely lights

My TV picture first garbled, then went away, but sound stayed on. Eventually nothing is on except the VIZIO light and some lights inside the TV.

ANSWERS:

onefancyfreespirit, first garbled, then went away" sounds like either the T-con board (most likely) or the backlight inverter. Post some images of all of your TV board's with your question so that we can see what you see.
