It could be a magnet in your speakers, it could also be from your cable. If you are using an extension cable this usually happens. If not, than it could be a poor connection... hope this helps!
something could be burned out inside the monitor that happened to one of mine before i dont think there is anything to do about it but im not sure if thats why
Hmm, its gone right now. Thank god. Anyways, im getting a new 21'' lcd monitor so I dont mind if this monitor is permanently messed up.
