The projector is only used in home... it has been ceiling mounted. Was working properly with no signs of any issues. Went to power it up the other night and nothing... no fans, no lights on the control panel and no sound of motors. I'm hoping that there is a fuse that is blown but I did not see any in my quick look inside. Also checked to make sure that the switch on the lamp cover was working properly... that tested okay. Anyway, before I toss it, I thought I would check here to see if you have heard of this kind of problem.
