    I bought this projector for its top class reviews and the quoted noise level. In all respects it has lived up to expectations apart from a slightly irritating low level buzzing noise that is audible in quiet scenes. I would have expected to hear a low level fan noise but this seems a bit more whiny than that. Has anyone else experieienced this?

    It might be the colour wheel - they can make a bit of a buzzy sound especially if they're of the larger variety. If you change between NTSC and PAL DVDs, does the noise change? The colour wheel should slow down for PAL.
