Re: vizio VU42FHDTV10A .. no pic or sound
No problem..I got the replacement board from Jimmy, bench checked it to make sure the 12 & 24vdc were there. both good..
Installed board, tv came on and worked perfectly, for 2 days..
Then the picture flickered, and the tv shut off, except for the white Vizio logo.
No 12 or 24vdc again. ..
Since the tv worked for a couple of days, I think it's another bad ps board, and notified Jimmy's.

Yes, I stated above that it does click.
I took the ps board with nothing connected except the ac cord, and connected the 2 AA batteries to the PSON pin, and the relay clicked, but still no 24 or 12vdc..
I then jumpered the 5vdc standby with a 1k resistor, and got the same results.
I think I am now convinced (just trying to eliminate other possibilities) that they sent me a bad PS board, and you are correct.
I will order another, and let you know.
Thank you much.Leave a comment:

The chip on both supplies is unreadable..I guess I have no choice but to order another ps board.Leave a comment:

The resolution on my phone is too poor for the entire board.
Yes, the relay clicks when plugged in, and when on button on tv is pressed.Leave a comment:

Re: vizio VU42FHDTV10A .. no pic or sound
What threw me is the original & replacement couldn't both be bad, so I looked at other areas, like the pson being too low, and the jimmy website told me it was probably the main board shutting down the ps board.
Anyway, the ics are:
IC802 .. 25923 DASD03..extremely difficult to read, and IC801 is almost unreadable.Leave a comment:

The large black capacitor at top left near the 2 blue ones?
(Boy, I hate no schematic repairs. Don't know how you guys do it.)
I'll measure it again later when I get home from work, but that's
what I measured last night. I used a metal chassis point, and then
an rca jack for common...Leave a comment:
