SOURCE: lamp replacement
Make 100% sure that your lampdoor is closed properly because there is a little swith on the lamp door that supplies the power to the mashine ( only when pushed in ) You'll see on the lamp door there is a pin that stands out - that pin pushed in the switch when the lampdoor is closed thus supplying power to rest of the components.

check out this thread: http://www.fixya.com/support/t138974-optoma_projector because there they say it's due to dust.
I'm having the same problems with my ep770, and am going to give it a try.

SOURCE: proector image is dim
I have changed the bulb on my LG projector recently. I found the rotating colour wheel to be full of dust. Upon opening the cavity where the light is redirected and reflected onto the imager, I saw all mirrors also had a layer of dust. I don't think it was so dirty that it affected the brightness of the image, but I cleaned it anyway using an earbud. I cleaned both sides of the color wheel as well. You need to be careful in working with the optics of the projector!

check the wireing in the new bulb . My new one had the wires in the wrong holes like if there are 4 slots in the connector then my orignal was in slots 1 and 4 the new one was in slots 1 and 3 so I took the wire out and put it in the #4 slot and put it in and unpluged the machine and did a reset and restart and it came on green. Hope this helps.
