SOURCE: Infocus LP70 dropped and now
try pulling the outer ring out a little while twisting it (you won't break it). then try the inner ring. if it wiggles, you need to take it apart- and that's not a pretty job.

if the fans aren't running, it's the power supply. if the amber is on and the button's won't turn it on, there is an obstruction under the button panel. if all turns on but the lamp and you don't hear a high=pitched whir, it's the colorwheel. if you do, it's the ballast.

Have you tried another lamp? Sometimes thats your problem, but I've seen a several occasions that the a defective power supply causes this symptom. Do you see an image flicker before the projector shutsdown? I do have some spare parts for this projector.
I'm on Ebay - gtitubro if you want to contact me through there.

I solved my issue with just simply upgrading the Frimware. Which can be downloaded from infocus website.

No it's not the color wheel. If the color wheel stalls the lamp will shut off immediately which is a built in protection mechanism. On the LP70 and 70+ there is a multi pin connector inside located at the rear lower left of the projector. This connector connects the main board to the DLP engine electronics. This connector is horizontal and approx 2 1/4" wide and 1/4" thick and about 100 pins. I have seen this connector not seated completely and many various video artifacts occur (even the one you describe) If you or someone you know is electro-mechanically savvy it's not difficult to open the projector and make sure this connector is seated properly.
You will need a TORX T8 screw driver.
Cheers
