VERTICAL WHITE BAR ACROSS THE LCD SCREEN

I'm assuming you're dealing with an LCD flat panel monitor.

If you've tried different input and from different computers and different cables, and you're still seeing vertical red lines, it's highly likely that the LCD is failing and there's not much that can be done easily to fix it. You will probably need to replace the LCD panel.

If the red lines are in different locations each time you power on, then it could be a controller board issue. But, if the lines are always in the same place, it's probably the LCD panel itself.

Green lines on LCD screens generally means physical damage. Did you drop it or bump it by chance? Physical could also include the cable that you are using. Try using a different cable, or make sure it is connected all the way.

Check the main filter capacitors at its power regulator board. Replace if found bulged or damaged. Replace all secondary side supply rails' filter capacitors too. The fault is with damaged electrolytic capacitors at the power regulator board itself.

This problems are a very tipical of the coded pixels on the LCD screen panel passes through the board that call the T-CON decoder board to causing this problems.Vertical colors lines display on the LCD screen panel happen by itself.Yes.The T-CON decodering board it is dying and shorting out.This T-CON decodering board sit in the middle at the botton of the LCD screen panel.Replacing this T-CON decodering board will solved this problems,if does not the LCD screen panel itself it is shorting out,than the tv it is not worth fixing,because changing the whole LCD screen panel itself it is not practical and the cost will be the same as a new tv itself.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decodering board for the replacement.

Sorry this wont help you much, but may put you out of your misery trying to repair it.
The LCD panel has failed. In particular the driver tabs that connect to the physical panel have failed and there is no way to repair them.
The only soloution is to replace the entire panel, a cost that would be close to if not more then a new TV of the same size.
I would put it on Ebay for parts (powerboard, logic board etc), and use the money towards it's replacement.

What is the error from installing xp sp3?
Is the white band always there? it is either a problem with the lcd panel most likely, or the graphics card. try a different monitor if you have one.

Usually when there are colored lines on the LCD its because the screen is going bad. Quick way to verify this, try a different monitor on your computer and if the line goes away then you know for sure the monitor is bad.

If you try a different monitor and the line remains then you know that the video card is bad.

whatever brand your tv is go there .com maunals it should show u what u need to know

It is the problem of monitor pcb in vertical section.check vertical ic for dry soldring. Resolder the ic if problem still on then change ic or check components related ith it. check continuity of vertical deflection coil.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FIXYA.

This is a common problem when LCDs are subjected to strong shock. Your internal circuits are damaged The panel itself may not be cracked but there is internal damage. I know of no cure or repair possible other than to replace the panel assembly.
