Question about Sony BRAVIA KLV-40U100M 40 in. HD-Ready LCD Television
I have a blue line running down the middle of the screen.
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.......
