I have a high pitched squeal in my monitor that appears aftear it's on for a while. It goes away if I hit the screen with the palm of my hand (keep some windex nearby, I'm OCD and fingerprints bug the hell out of me!) or if I turn it off, wait until I hear a static charge build up on the screen then turn it back on. It sometimes starts when a program changes teh resplution (and presumably the refresh rate.) My house was wired by poorly trained chimps who were clearly paid with moonshine and PCP, so supply-side electrical problems are a possible source. I can deal with it, but I really want to know what's causing it. I have two old Aiwa 45 watt speakers right next to it (the magnetic fields don't interfere with picture,) and I suspect they might be part of the problem, although it does happen when they're off.
Any ideas?
