I own a HL-R5678W DLP television and after being on for about twenty minutes an annoying sound will come out from the back of it. There is no color change or any visual problems with the picture. Is this the color wheel? The sound began when I installed a surround sound system in that shakes the walls. Could a fan or even the color wheel had its axis changed slightly by the copious amounts of bass to cause this obtrusive sound? What can cure this sound? After I turn the TV off the sound stops in about 5 to 10 seconds.
