I have a big screen phillips TV - not the flat screen type. One day I woke up and it had what I call color shadows. I'm not sure what happened, but I can't get rid of the shadow. We bought the TV from someone who misplaced the manual. Can anyone tell me what to do to get rid of the double shadow?

Could be bad reception... If you use antenna.. try to direct it in some direction and see if there would be some improvement. If you have cable TV.. check to see if it is in cable mode and not in antenna mode. If you use only antenna.. check your antenna..

Good luck.
