Hi Chipped Rice

The loud buzzing noise you heard was the colourwheel that gave in.

Now what happens is , the machine will turn on and go through the whole cycle and as soon as the colourwheel is supposed to start doing it's stuff the Projector will switch off because there is no response from the coulourwheel itself.

You will have to replace the colourwheel unfortunately as it cannot be fixed.

Thanks for using Fixya !

If a Projector starts playing on and off tricks I have found it to be 99% of the time a faulty Mainboard.

Done

Hi Tim

I've seen this many times. Only way to get rid of it is to replace the Mainboard.

This will get worse as time goes by.
