Try different cable, if you still get the problem after replacing cables, then you have a defective sygnal board (input board).

SOURCE: thin vertical line runs across the top of screen

Hi my name is Roety,
I can help you with your issue ,
 Try the format, aspect buttons on the Box remote, if the line is there on every input and effect the TV menu your panel (screen) is bad.
A new panel would cost as much as a new TV.

SOURCE: Sony kdl-v40xbr1 has horizontal lines

I'm having the same problem. I have noticed on mine that the menu when brought up is clear and I can see it perfectly. The picture on all the inputs is just as described above though. BUT, like I said I can see the menu just fine. This leads me to believe that it's not the panel. Anyone have a solution to this, or at least know what could be causing it?

Horizontal lines across screen of sony KDL-46BX450


Sounds like a T'Con fault itself. Re-seat all the incoming and outgoing flat cable wires to T'Con. If it do not help you, replace it with a new one of same part number. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.
