Line Defects On Vizio TV Screens

Sounds like a problem with the Vertical Video Card.

Have fun finding one. If your TV is still under warranty... send your TV off for repair.

Hi,
I saw your tv pictures at above mentioned website link.
It is LCD Panel (screen) problem, call Sony and ask for warranty cover to replace lcd panel.
Thanks.

I have the same TV, and a Sony BluRay player (not a PS3). I have the same problem.

I found it only does this when playing back 24p disks. My player has an option to disable 24p output to the HDMI, and it "fixes" the problem.

Not really a fix, but a workaround.

Not sure whether it is the TV or player, and sometimes I have fixed it by turning the tv off and on multiple times.

I am going to test the player on another monitor and see if it does the same thing. If so, the player is going back to the store.

Its hard to say this but your tv has a bad PDP Panel unfortunately the panel is not available for the tv. If not in warranty see if your home owners insurance will cover it.

your television is going to need an internal repair. most likely in the power supply of the television. it would be best to unplug the television until it can be repaired. If you would like to repair the television yourself then please use our premium service so an expert can walk you through it. Or you can search for a local repair service using our local repair search engine.

I suspect if you have green lines .you have a bad crt. there are three tubes red green and blue i suspect blue tube. tubes cost is around 300.00 to fix.


thanks doctor video


note sometimes you could adjust screen voltage located near the front grill black box . becareful high voltage ony a pro should do.

sounds like bad capacitors on the FMT board need replacing that is a common fault with the first generation DLPs There are 3 bad capacitors.

this could be three differnt things

1. the crt itself could be bad

2.the vertical ic on the crt board

3. the focus pack or focus block

suspect it's 1 or a couple of bad capacitors in the vertical deflection circuit the caps are in the 400 series, c400,c401,c402, etc... check or replace c414,c418 & c417
