How can I preserve my projectors performance?
It is very important in prolonging the live of your lamp to make sure while turning off your projector to let it cool down sufficiently before unplugging it. Failure to do so may result in an immediate loss of the lamp. Repeated disregard of the cool-down correct procedure will eventually cause your projector to stop functioning.
It is also of high importance to keep the filter clean and openings clear of dust and lint.
Make sure that the projector has enough "breathing room" with adequate ventilation, so that the unit doesn't overheat, putting extra pressure on the motor and the lamp.
