Because there are many high-end projectors in order to prolong the life of the projector , often using a self- heat protection, there is too much heat inside the projector generates encountered , working status of the projector will automatically work in this protected state , the projector will automatically shut off , and in this state , the projector for any external input control is not to make any response ; therefore this happens , you do not worry about the projector suddenly fails , you just automatically shut down the projector after about half an hour , and then follow the normal boot sequence to turn on the projector , you can let the projector to resume normal work.
