Re: Vizio M501i-B1 - Tries to turn on over and over but can't.

Any ideas? There's a multi wire going from the MB to the led driver board, and only one pin has voltage on it (12v). All the other pins are zero.

Yes, 19.74v going to MB and LED driver board....

So I've done quite a bit of research on vizio's not having power or not turning on. I haven't found anyone with my specific problem yet. It tries to turn on over and over again, but it never fully boots up. The white led on the bezel comes on and then dims out, and the red/blue led comes on on the main board. This repeats every 45 seconds or so. It finally came on in the middle of the night after about a week of this cycle, but now I can't get it back on again. None of the caps seem bulged either.

Power supply Model 715G6100-P04-003-002H.
Main Board Model: 715G6815-M02-000-005N....
