if this line is in the picture, that is possible burn in screen. if you have a black bar at the top or faint white lines that come down from top this is caused by defective filters in vertical circuit or bad vertical output. mch

Check the inteference,by other electronic devices such as radio and television and keep electronic ,magnetic devices away from the tv.
Does your aerial need more boost?
If you have a digital aerial inside your roof this can affect the signal.

Assuming all your inputs are connected properly and no defective cables or heavy overloads too your tv:
Inside your tv are a few cables one of which has a large ferrite 88ohm cylinder around it. This cable fails often and will cause strange affects on the screen. In most cases I have replaced the cable and took care of similar problems. Also the problem could be from the HD color convergence circuit IC also as it fails often too.
Re-check all of your connections too the tv be sure the cables are in working order and good condition. be sure all connections are proper in orientation, fit, and color code. Do this before honoring the warranty or consulting a repair shop.

SOURCE: Black Horizontal Line in Screen
hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works
