remove the top, front and rear panels (4 copper screws and 4 silver screws on bottom, 2 silver on back). there are 2 fuses for the power supply. the left board (looking from the rear) is the ac filter board, and has a fuse near the plug. the right board is the power supply/ballast board, and has one fuse near the back center, but it is soldered in. if the fuses are bad, replace only with the same size fuse. to replace the power supply (either board), just remove the screws and plugs and replace with part numbers 510-1908-00 (ac filter) and 520-0143-00 (power supply).

the caps dry out. look for bulging caps. you won't find a schematic for the ps boards. infocus had someone else make them. the problem seems more like a overheating issue. as for the other one with the "just the fans", check the colorwheel.

Replace the fuse only with the rated value. Before the projector is opened, the lamp must be safely removed and kept aside, Take all precaution not to touch with bare hands and to replace back into the holder with care.
