HELLO

By the sound of this you have a degaussing problem! I think what has happened here is the degauss circuit has failed and the usual cause is the POSISTOR.

What you should try to do is switch the TV on, then OFF again and leave it for 30 mins before switching on again. When you have done this and the problem is no better, then contact a service centre who will cure the fault for you.

Alternatively, try to borrow a DEGAUSS COIL and with the set on, switch the coil on and by using a circular motion go around the screen of the TV moving backward slowly as you do it. When you are say 6 feet away from the screen switch the degauss coil off.

HOPE THIS HAS HELPED YOU (:-)
