Before doing anything to your TV, try to reorient your
antenna. Then, if nothing happen, you may now call
service to adjust or replace component part.

Glare - HP Plasma TV Model PL4260N

Requires taking the back off: There is a module about 1 and a half inches square with 4 controls on it (looks like a small phillips screwdriver will fit.) Sits vertically. A yellow one on the lower left side. Tweek or turn it just a little about 2% and watch the picture and seen if the problem goes away. First unplug the tv before taking the back off and when back is off position the tv and yourself to turn the control and turn the tv on. You will need someone to turn tv on for you. Then do the tweeking with someone watching the picture for you
