Re: va26lhdtv10t vizio

I took panel out because i noticed with panel laying face down and looking at front of it something in screen that looked like glass shards took apart to get at them to see what it was ,it was glass shards from edges of panel.

probably why it went to white screen

Re: va26lhdtv10t problem

I am also trying to fix a vizio VA26LHDTV10T. I have located a broken component (smd capacitor ??) on the lcd board in picture. ((I have no camera available, so borrowed a pic from bobbyd40's post to show what I am talking about.)) It is CP31. I need to find out if it is indeed a capacitor and what the specs are for replacing it.
I experience loud snapping sounds from speakers and black screen upon powerup. If I disconnect the lcd ribbon from main board, sound stops and powers up to white screen.
any ideas???

CP31 is a cap, it is also conNected in parallel with CP30. Why do you think it is bad? does it show <1 Ohm resistance reading?

Re: va26lhdtv10t vizio

sending new pics (taken by phone) showing broken capacitor. Pretty obvious that it is no good.
any ideas why I am getting the feedback noise through the speakers?

Re: va26lhdtv10t vizio

When the MLCC cap is cracked, it will short out. So use the Ohm meter to find out if it is showing short or not.
Disconnect the LVDS (FLAT cable) cable between the screen and the main board, then the TV should function normally with sound, you just will not have picture on the screen, you just see glowing screen.

Re: va26lhdtv10t vizio

you are very correct. I have previously disconnected the cable and found what you describe. Last night I replaced the cracked cap and set is now working properly.
So, after 3 bad caps on the power supply (1000uf, 35v) and one on the T-con board, I have a working tv. Thanks for all the info and help. Hope others can benefit from my bad t-con cap problem.
