Chosen Solution

I have a maybe six inche white bar running vertically, slightly left of center on the screen. Otherwise, the flat screen works find for Samsung model number LN46D503F6F. Seeking advise on repair guidance.

This is a sign of your LCD panel going bad. Unfortunately for the cost of repair, even if the repair is available, it wont be worth it with the drastic price reduction of 1080p lcd’s.
