Re: Vizio E471VLE No Power

Sorry for bringing up and old thread I have the same set with exact same issue as the OP. I have 5.2 v on 1-3 @ cn201, the rest of the pins nothing. Fuses test good and 60 volts on both sides of f100, cx101 & cx102. Purchased a replacement board from shopjimmy based on diagnosis followed here and exact same issue. So either I got a bad board having same issue or I would assume it is my main board that was the failure.

I did the jumper test discussed above and all backlights come on.

L220 has almost 16 volts(15.86 to be exact).

Any further input on diagnosis?

Unplug cable from powerboard to mainboard again, do the jumper test if backlights come on and stay on, powerboard should be ok, then a replacement mainboard should do the trick. Might not work tho if something went wrong.
