Ok I'm no TV tech but Ron turned me into one so I'll try again but got a co-workers Vizio VO420E set that has a loud humming and I have the board in front of me and can't see any fried parts or components but the caps C473 and C764 have some discolorization which I would think are before the backlight outs of CN-204 & 204. The owner thinks the noise is coming from the HV trannys T-701 and 702 but I'm not sure.
