Hi a newbie here.I have a va26lhdtv10t vizio i am trying to repair.vizio logo yellow and white when powered on screen lights up with back light and no picture just white screen with sound.Visually checked boards for bad caps and loose connections.Checked voltages to main board all correct except PS on only shows .998 volts.Changed main board with another from shopjimmy.com no difference. also twisted and wiggled front frame no change and unplugged ribbon cable to main board and tcon with no change. I have attached pics of power board. any help or suggestions would be great thanks to all. great board

Check the fuse(s) on the t-con board, can you post a pic of it?

Re: va26lhdtv10t vizio

I have it apart and tried to take some pics board is about two feet long and hard to get it all in one pic i took a few of different sections.Don't see any fuses are they surface mount gold things with no markings?.

Re: va26lhdtv10t vizio

It looks like FP1 is a fuse, with the K marking on it. So there is no t-con board it's integrated in the panel right?

There is one in Pic 5 - It is white with a K on it. Meter on 200 ohms should read the same as touching the probes together?

Re: va26lhdtv10t vizio

Correct it is integrated. i will check that fuse and let you know thanks.

Re: va26lhdtv10t vizio

FP1 fuse with k tests ok no open.

Re: va26lhdtv10t vizio

Can u safely check for voltage on each side of fuse?

[bobbyd40]

Re: va26lhdtv10t vizio

FP1 checks OK no open. When i first checked TV it powered on and had a picture on left half of screen and right was full of color vertical lines i wiggled ribbon cable and pic came back on right side with just one red vertical line. so i unplugged both ends of ribbon cable and plugged back in and now no pic at all except white screen.I have messed with it since with no change from white screen, strange?

Re: va26lhdtv10t vizio

When you had the lvds flat cable out and put it back in did you get it the right way round?

[bobbyd40]

Re: va26lhdtv10t vizio

no voltage reads 0.01

[bobbyd40]

Re: va26lhdtv10t vizio

yes cable is fold and taped in such a way you cant switch it around

Re: va26lhdtv10t vizio

The ribbons look like they may not be fully seated try reseating all of them. I think that blue line is usually in further..

[bobbyd40]

Re: va26lhdtv10t vizio

ok will give that a go

[kevinm34232]

Re: va26lhdtv10t vizio

You checked voltage with TV powered on right?

Re: va26lhdtv10t vizio

If no voltage at the fuse test near the socket at Vin12 and if none there then we will need pictures of the area around the lvds socket on the main board.

Re: va26lhdtv10t vizio

just pulled LCD panel right out glass is chipped on side edge and top edge guess it is shot will sell good parts from it and write it off as a learning experience. thanks for your help

Re: va26lhdtv10t vizio

just pulled LCD panel right out

Why? Not getting voltage to the board is no reason to take the panel out?
