My projector doesn't want to startup anymore

When I try to switch it on I can hear the fan or colorwheel starting to spin, but the after 4 seconds it stops and the TEMP and POWER lights remain red.
I don't feel like wasting my money anymore sending it back again(about $250 for oneway shipping). Last time I had to send it back, because I had lots of dead pixels(stuck mirrors).
I think it might be the colorwheel, because a few days back I thought I heard a weird sound and sometimes it looked like the image's color changed a bit..
Anyone had the same problem before?
EDIT: I have the Casio XJ-A230. I just ordered myself a LG PA70G. Hopefully I would be able to live with the diamond pixels and no zoom...also I hope the focus is 100%.
On the plus side I won't see any rainbows anymore...I hope
