My benq projector keeps blowing lamps.
first, blow out any dust with canned air. dust keeps in the heat that the projector is trying to expell. next, don't buy cheap lamps from random websites. you get what you pay for. and make sure you have the correct lamp that the manufacturer states. also make sure there is sufficient space around the projector. the vents cannot be blocked. lastly, reset the settings to factory default. many times there is a low power/full power setting. the fans go on full on high power. there should be at least 2 fans. one for the lamp, one for the optical engine. may be one for the power supply. if the one near the lamp is not blowing much, replace it.
