Question about InFocus LP70+ Multimedia Projector

1 Answer

Fan problems The screen says "Fan problems. One or more of your fans have stopped." What do I do? I called InFocus support and was told that the vents may be dusty and to use a vacuum cleaner on low to **** away the dust. I did that, and the same message comes up when I plug up and turn on the projector. Any other suggestions besides sending it in for repair?

    I get the same message. I did pull out the bulb and can see that one of the fans is not turning so this appears to be a real fan problem. Are these user replaceable?

Find out which fan is not working and clear out the obstruction, if any. otherwise, you need to replace it. they are easy to replace once you find out which one.

InFocus IN2102EP. After about a hour the it starts to flicker between a white screen with "NO INPUT" message and the image. It stops for awhile and then stars again. It is running from Computer #1 input....


It MAY be a thermal problem.

Make sure there is no obstruction on ANY side within at least 6 inches.

Sometimes they put these in cabinets and that is a no-no as it reduces air circulation/

Check that the fan and all the vents are free of dust and if it has a filter, the filter is clean.

Try putting an additional fan blowing on the unit to see if it runs longer.

Also check your cable connectors are properly seated and screw locks are set. As things warm up, the cable might be marginal if not seated.

I HAVE AN INFOCUS SCREENPLAY 5000 PROJECTOR THAT DISPLAYS THE MESSAGE "ONE OF YOUR FANS ISNT WORKING SO SHUT DOWN WILL OCCUR SHORTLY"... PLEASE TELL ME WHAT I CAN DO TO FIX THIS ISSUE. THANK YOU IN...


there are 2 fan assemblies in this model. a double fan for the lamp, and a single fan for the dmd chip. check for obstructions through the vents (pieces of plastic or paper will stop the fan). if nothing is in there, you could buy the parts from an infocus service center and replace them yourself or send it to them to fix. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

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.

SP4805 Fan Issue


the fans in these models do not have a speed sensor wire to let the main board know to turn off the lamp to not risk overheating. so if the fan goes, the lamp remains on. however, if the lamp exploded, check the vents for dust. there is a temp sensor that will shut down the projector if it gets too hot. if the vents are clogged, blow the dust out of the projector with canned air. the dust keeps in the heat that the projector is trying to expell. easiest way to repair the fan w/o buying a part: splice the fan wires together. they can share voltage. if the 80mm fan does not work at all after that, replace the fan (pn: 526-0192-xx).

4805 infocus projector


it is the colorwheel bearings going slowly due to excessive dust and heat. remove the lamp and push in the switch actuator on the lamp door frame. turn the projector on and see the colorwheel spin in the lamp housing window. does the noise happen when the wheel spins and stops when the wheel stops? let the switch actuator go. does the noise stop? it's the colorwheel (pn: 525-0146-00). you can get it through an infocus service center. try av solutions in ny. www.avsolutionsny.com

Error "Fan Stopped"


yes. it needs the third wire to sense the fan speed. without it, the projector assumes that the fan is not running.
