SOURCE: boot up problem
It is dust built up inside on the fan wheels. You wouldn't believe it but it is just dust. If you are mechanically and electrically inclined, take apart the housing and blow out the entire unit with compressed air especially all the vents and blower fans (my Optoma has 3). It'll work like new again. I was completely amazed.

If you have any video at all and it's only Black and white there is a 99.99% chance that your Color Wheel has lost all of it's glass color filters.
You can confirm this by removing the lamp. then look straight into the projector where the lamp was and you should see the color wheel of colored glass segments (Red, Green and blue) I believe you won't see them because they came off of the wheel.
Also if you lift up the projector and turn it around in various angles and you will hear the small pieces of broken glass from the color wheel.
Unfortunately you will need to take it to an authorized service center for repair. Be prepared to spend upwards of $300 for the repair.
Cheers
