The black line indicates that either the flex cable that connects the panel to the buffer board has come loose or the panel is bad. Try to reseat the connector located inline with the symptom seen on the screen, if it's loose or inserted crooked, the panel will show this problem. Good luck. Joe Weibel customelectronics.org

If your set is a plasma, this can be one of two problems : either there is a loose connection (one of many, many connections) between the plasma screen and the driver board, or one of the transistor devices has blown. Try GENTLY applying pressure to the opposite ends of the TV to give it a subtle "twist" (please be careful!). Sometimes moving the set to a different location will produce the same effect. If it's still under warranty, call your dealer. Vertical stripes are a common fault with plasma technology I'm afraid! :-( Next time, go for LCD!

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.
