My tv has a blue line down the middle

The tv T-CON board it is dying to causes this problems.This T-CON board sit in the middle at the bottom of the tv plasma screen panel.Try website like Ebay.com to buy a whloe new refurbish T-CON board for the replacement.

the problem may be a combination of three things, it may be the lcd panel, the main printed circuit board, or the logic printed circuit board, the small circuit board that the panel plugs into sometimes. replace either one at a time or all, these situations always come with some trial and repeat testing. Good luck.

You may need a pixel fixer, that can be found at Wal-Mart!

LCD needs to be replaced.
Common problem called "Tab separation".

Your control board and address circuits need to be examined. This could be a component problem or a simple fix such as installing a new ribbon cable from the control board too the address circuits on the LCD panel itself. To do this would require a technician, but before this issue gets worse you should have it repaired.....check to see if its under warranty.

Some people have tapped the back of their tv and got rid of vertical line interference. But , I wouldn't suggest that method.......
