Hi morpheusj30

Yes , I've requested it yesterday and should get it on Monday 12 May from Optoma.

I will however only be able so send it to you on Tuesday , as I'm not in the office on Monday.

Hi guys

Your best bet on getting your hands on a Service Manual would be to contact Optoma themself.

As for changing the colour wheel , it is pretty straight forward if you were able to open up the unit and get to it.

The colourwheel is mounted with three tiny scrws to a bracket in which it sits. And the bracket in it's turn is fastenend to the body of the Projector with two tiny screws.

First unscrew the bracket from the casing of the Projector and then take off the three screws that holds the Colour wheel to the bracket. Replace and do the whole proses again - but obviously just the other way round.

This is really easy to do yourself.

Give me a shout if you need any further assistance.

Thanks for using Fixya and good luck.

Very odd problem. Depending on the hours of the projector it could have some glass in it that over heated. Contact Optoma directly, my guess is they will work with you.. good luck
