Question about InFocus ScreenPlay 4805 Multimedia Projector
If the fan spins freely the problem is most likely not the fan but the 8 pin smd Mos-Fet fan speed control current amp has failed. Not difficult to replace and are a common problem with these projectors.

If the voltage is ok for the 80mm (pn: 526-0192-xx) and the 60mm (pn: 526-0193-xx), replace them. you can get them from any infocus service center. try av solutions in ny. www.avsolutionsny.com. however, in order to replace them, you'll have to remove the top, front, and rear panels, remove the 2 power boards, the board shield, and the lamp housing. now you can unplug the fans and remove them. warning: be extremely careful around the colorwheel and the light tunnel (under the colorwheel). they are fragile and may fracture easily.
