Question about InFocus ScreenPlay 4805 Multimedia Projector
The problem is not with the fan its the main controller board, that for some reason becomes faulty with these models and stop supplying the fan with sufficient voltage to operate, not really worth fixing because locating one is hard enough and then the part costs $578 (as quoted for my one). What I have just finished doing to mine, is hard wiring an old nokia charger (transformer) inside the projector, connecting it to the underside of the power supply board (to the 240V inlet plug) which supplies the fan with its own power supply thus fixing the problem without spending hundreds. The down side to this is the fan will keep spinning as long as the projector is plugged in (could be fixed with a switch). This isn't even an issue for me because I always unplug it when I'm finished with it anyways, and it allows the bulb to be cooled for a lot longer than the factory set time, and also saving me from spending thousands on a new projector haha =), hope this help in some way or another.
