My HD-72 started making a high pitched noise - research seems to indicate it is a color wheel? The projector is two years and 2 months old. (2 months out of warranty) 
Could this high pitched noise be anything else? Doesn't bother anyone else but drives me crazy. Fortunately if I turn it up a bit I can't hear it anymore.
Should I expect it to get worse?
