Re: Vizio VX32L turns on with backlight, no video or sound

I've seen some references on how to confirm one of these regulators is in fact bad. I found a video on Youtube (referred to in this thread I think) but the video was fuzzy.

If the output is supposed to be 3.3v and is low, this guy connected a 3.3v power source (2 AA batteries). He then powered up the TV and it worked.

But I wanted to make sure I'm connecting the test power source correctly:

a. + side of battery output to the output terminal of the regulator
b. - side...
