I have a RCA 20" TV which is about 12 years old. Whenever I play a movie through my DVD or VCR player or if I watch TV through the VCR's tuner the screen becomes distorted whenever there is a bright flash such as an explosion. The distortion takes the form of a split second vertical hold roll with maybe some color bands. This only happens when I watch something using the TV's A/V inputs (composite). If I hook up a player directly to the TV without going through a receiver or switcher everything is fine. I don't use switchers anymore since I replaced my obsolete receiver with a modern one. Is my receiver overamplifying the video signal? Or is my TV incompatible with today's modern equipment? Or maybe my TV is just dying? Someone please help me with this annoying problem!
