Question about InFocus LP70+ Multimedia Projector
When the projector is turned on, it makes some noise likely from fan and there is no light.
I am having the same problem. Projector starts up and the main screen flashes and turn off into standby mode. Open the projector and the fans and colorwheel are spinning. Not sure if its the bulb or power supply.

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.
