I've owned a Mitsubishi HC3800 for a few weeks now and I've been running into some image shaking issues. I've done some research and some individuals suggested switching the lamp mode to low. I've played around with both the low and standard lamp modes, standard mode appears to be a bit better then low. The projector is mounted on the ceiling to a Peerless PRG-UNV Precision mount. It appears that everything is tightened properly etc. If I hold the projector a bit, the shaking appears to be reduced. I know this issue is caused by the fan but I was wondering if there was a solution to this. Maybe rubber washers between the projector and the mount? How about placing some weights on top of the projector? Any suggestions are appreciated!
