SP4805 Fan Issue
the fans in these models do not have a speed sensor wire to let the main board know to turn off the lamp to not risk overheating. so if the fan goes, the lamp remains on. however, if the lamp exploded, check the vents for dust. there is a temp sensor that will shut down the projector if it gets too hot. if the vents are clogged, blow the dust out of the projector with canned air. the dust keeps in the heat that the projector is trying to expell. easiest way to repair the fan w/o buying a part: splice the fan wires together. they can share voltage. if the 80mm fan does not work at all after that, replace the fan (pn: 526-0192-xx).
