X1 multimedia projector

Take the top off and verify that all of the fans are on, there are 2 behind the power supply and one behind the engine. If the unit lights up when the top is off, then the wires above the dual fan assy may be putting pressure on the fan frame while the top is on causing one to rub or not turn at all. If this is the case, unplug the power and try to route the cables thru the notch in the top of the fan assy a little better. If any fan isn't working, the unit will not light. This could be due to a main board problem or a bad fan itself. If the colorwheel is stuck, the unit will light and then shut off. Also, depending on the age of the projector, if there isn't a green wire going from the front of the main board to the bottom of the power supply ballast, the power supply will need to be replaced or upgraded by a technician.

it's the fan. if it won't spin full power, it can't cool down the projector and it'll shut down. there are 2: 60mm (part # 526-0153-00) and 80mm (526-0152-00). both can be purchased from infocus or an infocus service center.

you can plug the other fans one by one into the working fan's socket to make sure the fans work. if they don't replace them. if they do, you have a main board issue. the fans have a 3rd wire that senses rpms, so they can't be rewired.

if the fan is not moving but still receives voltage, just replace the fan. if you're sure the fan works but no voltage, hope you're good at soldering. you need to remove the main board and solder a jumper from the bad fan's power and ground to the working fan's power and ground.

the bulb may have burst from overheating from a fan not working to cool it down. and it can be replaced. it does take, however, a while to replace it because you have to take half of it apart. but make sure it's the fan first. take the lamp door off and remove the lamp. use something small and thin to push in the switch that the lamp door usually activates. turn the projector on and see if the lamp fan and the colorwheel (the multicolor glass disk) are spinning. if the fan spins, the noise may be from the colorwheel motor going bad. the fan can be purchased through an infocus authorized service center. check the website for the closest one. but the colorwheel for the x1 cannot be purchased seperately from the optical engine, and that costs a fortune. but here is the part number for the 80mm fan- 526-0152-00.

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).

3 red flashing is a lamp error, not the fans. the lamp has a problem striking. make sure it's pushed in and plugged in all the way. if the lamp is not that old, the power supply needs replacing.

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.

Hi topher1234

I will need your Make and Model of the Projector , before I can do a diagnosis. Also include if this is a LCD or DLP machine.

Together with the above , can you feel any vibration on the Projector when you place your hand on it ?

something blew the fuse the first time. if it blew again, the issue remains. something may be arcing. check near the plug, or if there is anything bouncing around in there or a crossed wire.
