Hi

Have you tried using a new video cables? Alot of times when a composite cable(or others) get cracked, or a loose connection this is an issue.

if not then its likely you have a problem known as vertical banding......
I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.
It has a small red - d7a305f.jpg


Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

if your tv is not under warranty... and if you are comfortable repairing the tv urself..... go ahead with the below repair....
please make sure that you have unplugged everything before venturing for the repair..... as these units have pretty high voltages.... also when ur opening the unit make sure u do not accidentally disconnect the solders.... that would cause further complications.... o proceed with the below steps only if ur 100% comfortable....
Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel

Hi,

Try altering your display resolution in all its variables.
try altering RGB settings, contrast and appearance settings. If this does not work, most likely a hardware screen failure.

You have a hardware problem, you cannot fix it using the menu. in fact you could make it worse.

Try googling DIY convergence repair if you can solder.

did you check the six 3.5 pico fuses that are next to the ICs? They will often be open ( blown) when the ICs fail. Also check the two 5 amp IC protectors on the G board as those protect the two ICs so its possible they have blown also a 5 amp pico can be substituted for the two IC protectors.

VIZIO P42hd PS42a plasma Picture has two vertical lines (one red/orange, one blue) going down the right-hand side of the screen. Lines are clearly visible


The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

Vertical line on side of LCD TV


Modern televisions have screens divided into sections. Each section controls all the rows in its area, and it is controlled by its own video separate video driver. If you are missing a line in a section, then a problem has occurred with the driver board in that area. It will be pretty expensive to fix, I hope your warranty has not just expired!

WS-55809 - Video pinched in center, distorted, yellow/blue/red glow


This doesn't sound like a programming issue. I had a very similar problem about 6 months ago and I fixed problem. I had cold solder joint on the video power board. It was the board in the middle. The power supply was to the right. The video board had a driver with a bunch of legs. About 7 solder joint where cold or loose. I solder the board and my mitsu wide screen was fixed. Hope this helps.
