My projector M260X also was showing fan problem with 6 red blips by the status indicator. Upon checking I found one of centrifugal fan is not running. I did not pull out the fan. Instead I released the connector tab from the motherboard. After inspecting, I found the fan has 3 wires, Red, black and white. I cut the red wire and black wire and connected to a laptop 12volt adapter to the red (+12v) and black (-) wire. The fan started to run. Remember the white wire is for relay of fan status to the motherboard. Then, I pulled out two points from another 12v fan connection from the fan and connected the former fans +ve end to the 2nd fans +ve wire and (-)ve to the (-) terminal. On powering, the both fan starts to run and projector turned on. In your case, if the fan is found to be bad, the just remove the mother board only. You will be able to pull out the fan without disturbing the optical portion.
