Hi there.

Yes, this is a very common problem unfortunately.
It is in the controller board, which stops supplying the fan with enough voltage to start or continue to run. I fixed this problem using an old nokia charger, and some kiwi injinuity which fixed the problem brilliantly and no-one will ever notice =)
If you would like, I can tell you how and maybe get some pics of my one?

Cheers

I also had the same problem that the fan had died. Using the X1 service guide (http://members.shaw.ca/netguy/x1serviceguide.pdf) which is really close to the X2, I opened up the X2 (not for the faint of heart). I measured the the voltage to the fans and it was only 6Vdc, it should be 12Vdc. The smaller fan was running but the larger one (for the bulb) was only twitching. Thus the reason that the bulb burned out early. So I used what someone had recommended earlier and provided external 12Vdc to the fans. Works great. I happened to have a nice 12Vdc 1.5A "brick" laying around as a power source. You can find them at Radio Shack ($35 needs to be at least 500ma). You could wire the brick directly to the fans but I installed a power jack on the side of the plastic housing, which matches the power plug on the brick - so that I can unplug it. The only trick when using external fan power is that you need to run the fans for about 3-5 mins after the lamp is shut off to allow it to cool down gracefully. Normally the projector handles this for you. So you need to first power off the projector but leave the fans running for a while. A small price to pay for a cheap fix. Enjoy.

    If you have to replace the fan, take it out and go to the good computer store that has components like Tiger Direct or CompUSA. They will have replacement fans. Cheaper than going to the manufacturer.

    John: I considered the cool down issue; hence my wall rat is downstream of power plug/switch , Human nature is first turn x2 "off" then as some point, unplug unit. The delay allows fan to run for a while. See my ugly work around athttp://www.fixya.com/support/t2940267-fa...

Hi There

If this problem still persists after replacing the fans , you should check the Powerboard that supplies the fans power.

Have Infocus X2 projector. When on a dark shadow line appears down the left side of screen. Could it be a bad lamp?


no it is not lamp problem. it must be light tunnel problem.
after lamp there is tunnel for light travel, made from 4 pieces of mirror.
this tunnel is glued. glue tend to break in time so the tunnel is no longer doing its purpose.
open this part of projector, there should be 2 little screws holding it. repair it by reposition mirrors and glue them from outside by little drop of temperature resistant and elastic glue. that's it !

How do you change the colour wheel


remove the rear panel, front panel, and top. the colorwheel is between the lens and the lamp. removing it is easy, but to unplug it, you need to remove the 2 power boards, the shield, and the fan/lamp housing assembly. there is a tip on this site with a detailed description on replacing it. it's under infocus x2. the x2 and the sp4805 are basically the same machine.

Infocus X2 projector shows picture in black and white only...


that little glass square broke off of the colorwheel, and it needs to be replaced. that yellow/gray line is from the light tunnel collapsing. both parts can be purchased and replaced by you. if you don't feel comfortable doing it, you can send it in to an authorized service center. try av solutions. they're pretty good. you can purchase infocus parts from them, too.

Fan wont turn on infocus x2, instead makes funny siren noise and attempts to turn. Small fan inside works fine, larger one cant but will turn if touched, so doesn't seem to be anything in the way of it.


This problem is almost never the actual fan itself failing..
The intermittent whine you hear is the result of the Mos-Fet fan driver chip which is the speed control current amplifier.
It's an 8 pin surface mount chip on the bottom of the main (lower) circuit board. This is a common failure with these projectors.
The chip is inexpensive and needs to be replaced by someone who is skilled in surface mount component technology. You can replace the fan but you will still have the same problem. Hint, the bad chip is not the one closest to the large fan connector... It's the one closest to the small fan connector and it will measure 45-60 ohm's between pins 7 and 8. the part (rns70d) is discontinued however there is a replacement that can be purchased at...

Infocus lamp not firing


more then likely the ballast has gone bad and the lamp is not getting the right voltage to fire. Only other thing you can do is remove the lamp the turn the power on and check the voltage at the connector. This will not check the triggering voltage mine you only the lower operating voltage. But since you have replace the bulb with a known good one I'm betting on the ballast is bad.

Infocus projector power supply dead


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.

Infocus x2 dose nothing


Assuming the power outlet and cable is OK the most likely problem is the power supply and needs to be replaced.

Projector will not power on


Check your cooling solution wether its a fan malfunction or if it needs a new fan - or h20 cooling system

if not its either the power supply or something serious - send it to manifacture or go to a in-store repair

(it could be the dust protector)
