Hi there.

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.

Fan not working in my projector

First of all check the power to the fan and if present the fan is faulty. If not there is fault on the power supply or the control circuit.You need to check if the filter is clogged and the filter door is closed properly as the lid has a micro switch which will cut off fan when it is open.

Steady red status light on NEC VT45 projector. Would not POWER ON. LAMP was replaced with a new one

the power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try

Fan not going round properly in Infocus projector.

you have to remove the top: 8 screws on the bottom, 2 or 3 on the back, undo the clips in the top vent on the rear (using a flathead screwdriver), remove the rear, unplug the wires, lift off the top and front (from the front). there are 2 fans, a 60mm and an 80mm. both are available from an infocus authorized service center.

Fan stopped working then globe and remote stopped

Hi there

Yes, unfortunately it is another common fault, sad really lol
The remote not working could be due to the little remote sensor board that you will have seen when taking it apart (I have a service manual if you would like it), do any of the buttons on the unit itself work that you know of?
The bulb not lighting issue can be a number of things, usually a safety wise. When you replaced the fan, what were the specifications of the fan you used? Usually computer fans differ slightly to the ones used in this model, and can cause them to fail and the unit to over heat. If the projector switches on for a bit and then turns off, it means the safety thermostat in it is cutting out preventing overheating, you could try bypassing it just to see if the bulb will ignite. I know it may sound a bit dumb but check the safety switch on the door is fully in?
If you would like the service manual I could send it to you, I found it very helpful with mine, also a forum, I think AVS was extremely helpful aswell.

Sorry if this doesn't help, I will look into it further

Infocus sp-4805

What I have just finished doing with my x2, because it was the controller board not giving enough voltage to the fan. I used my kiwi initiative and hard wired an old nokia cellphone charger transformer inside the projector and connected to the 240V inlet from the underside of the power supply board, this worked brilliantly and supplies the fan with the power, the only dis advantage is that the fan will keep spinning as long as the projector is plugged in (could be easily fixed with a switch), but the way I see it it's better for me because it cools the bulb down a lot longer. Saved me from buying a new projector Lol, if you would like I can send a pic of what I have done?
