A while back I had a problem with my boat. I'd put a new stereo system in with big magnets on the speakers. One of those speakers was directly above the TV. When I turned the TV on, the picture was all green, and after some investigation, I found that the magnet had screwed up the picture tube, and their seemed to be no way to correct it short of moving the speaker (leaving a large hole). I talked to an electronics buff friend of mine, and he came up with a solution. He supplied me with a type of sheet metal that shielded the TV from the magnetic field of the speaker. It was quite thin, and was cut with tin snips. Placing a piece of it between the TV and the speaker completely cut out the magnetic interference. Don't know what effect the metal alone will have on the compass.
