The projector shifts back and forth between two tints of color every 8-10 seconds. I have installed a new lamp but it continues to do it. It is being run off of HDMI cable with a 50'+ cable coming from a laptop for a large meeting room (church) gathering.
Look to the color wheel for your problem. They do wear out.

your gonna need to get a service manual from the manufacturer and do a convergence alighnment with the on board generator. Unless some unknowing hands have been inside the unit.?? Contact them here at this link Good Luck [email protected]

Without more info, I'll tell you some things to check...Make sure the power cord is still plugged in firmly. With the unit unplugged, check the lamp for damage, looseness, etc. Was the unit hot when you moved it? If it was, the lamp was more prone to damage due to the heat. Always be VERY gentle if you have to move a hot projector for any reason. Did the unit sustain any hard impact while moving? Impacts crack boards, loosen connectors, and damage lamps. Make sure the lamp door is closed completely--there is a switch on the door to prevent the projector from coming on if the door is open. Make sure you didn't press any buttons on the unit too hard while holding it during moving.
