Switching on the tele this morning, the normal blue background is now half red and half blue.....(top half red) so that while watching a program now people have green faces.......weird!!


Good Day, deejay268;
Try resetting the entire system by unplugging the tele and the boxe. Unplug from power source for 3 to 5 minutes, then re- connect. Good Luck, big IRISH.

Your problem is a bad main filter, a regulator IC ,and or a combination of a convergence problem along with a vertical IC going bad. This set is not something you should mess with unless your a trained tech. Please seek a pro to assist you with this repair. good Luck
