Sounds like your unshielded speakers have slowly magnetized your TV tube. First, Move the speakers at least a foot or two away. Next, try turning the TV on and off several times. Most have an auto-demag circuit in them that works when turned on. If this does no good, you may have to bring the TV to a shop and have them use a professional coil-type manual demagnizer. They will probably charge a fee, but what can you do. If the speakers have to be close, get some shielded speakers. --Tom
Speakers causing problems with TV
I have a pair of speakers sitting right next to the sides of a 32" TV. They have been in this position over a year and recently have been noticing color/tint distortion with the TV. I have tried moving them further away from the TV, but the problem remains. Has anyone experienced this problem? What can you do short of moving the speakers into another room?
