Question Mitsu HC4000 high-pitch noise - colour wheel failure?


Novice Member
I've got a Mitsu HC4000 which produces quite loud high-pitch noise once the power is turned on. After some search on the Internet it turns out that it might be colour wheel problem, which makes sense because when I turn it off, even though the fans are still turning, the noise disappears. It's really a shame as it produces a quite good image quality even when the noise is on. I've searched on ebay but apparently Mitsu doesn't produce projectors any more and the components are very rare. Anyone know how I could get it repaired please? Many thanks in advance.
