Speakers causing problems with TV

after you make sure the tv is ok just get some magnets the same size as the magnet on your woofer and stick it on your woofer magnet.tadaaaaah you have shielded speakers,or like the other guy said go buy some shielded speakers

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
