Fan operates on x3 but no picture

I have a infocus x3 that when i power on does the normal whine and hum but then shuts off and comes back on and does this for a minute or two while blinking a green light. then red light blinks. now i probably haven't taken care of the bulb that well is it blown only had 700 hours on it. it also had a thin line running across the top of the screen for several weeks before it went down.

Very likely your bulb. Could also be your ballast.

Noise probably from fan


Amost certainly a failing bearing on a fan motor, or, if you are really unlucky, the colour wheel drive motor. Most probable is a fan fault. The only real way to isolate it is to test each fan in turn until the faulty one is found. If you are lucky, the faulty fan may feel stiff or rough when you rotate the blades gently by hand. If it's not a faulty fan, you are in for a rather expensive repair....

The bearing cannot be repaired - the faulty fan must be replaced

Infocus IN10 projector, when I turn it on the light blinks green for a while (with no picture) and then it shuts off and blinks red (more than 5 blinks)


if Lamp or projector shuts off after running a short period of time, This is usually a thermal issue caused by excessively
high internal temperature. The high temperature
could cause a component on the controller ECA or
the power supply to fail when it gets hot.
First you need to check the fan operation, Are 3 fans, two for lamp and one for the color wheel. Check the elevation foot, if something is broke maybe something stop the fan.
Remove the lamp module.
Examine the fan assembly through the recess in the bottom case. Plug the projector in and turn it
on. Both fans in the fan assembly should start up and run for 5 - 10 seconds, then shut down
(because there is no lamp installed). This is time enough to make sure the fans work properly.
Make the same for the color wheel fan, you need to remove the top case.

the high-pitched sound is the colorwheel trying to spin up to speed. that may need to be replaced. check the inside of the lamp for bulges, black spots, fogging or flaking. if it has any of those, replace the lamp. you can get parts from an infocus service center or send it to them for repair. either way, try www.avsolutionsny.com they're really good. if you want to replace it yourself, there is a detailed step-by-step on my "tips" area. it's the same as the infocus x1, x2, x3 and sp4805. click on my picture and scroll down to tips. good luck!

if you hear chirping or a loud buzzing, you have a bad colorwheel. the lamp won't turn on if the colorwheel doesn't spin as fast as it needs to. if you don't hear anything like that, you need a new power supply. the lamp striking takes a lot of power, and if the power supply can't handle it, it shuts off. you can get the part from an infocus service center and replace it yourself, or send it to them for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

it's not recomended to run constant for a day or longer. it may have overheated the lamp. especially if you've never cleaned it out before. take canned air and blow out any dust. but first remove the lamp and see if there is dust blocking the side vent. if there is a lot, the lamp overheated and prematurely blew.

The fan is probably on it's way out and cannot produce enough air flow to cool the lamp. Replace the fan with the same ratings as the original and it should work fine. The only other thing would be a problem with the power supply not supplying enough power to the fan, but, a bad fan is more likely.

Infocus in26 fan runs continually


Hello,
The fan does run continuously on this projector however it should be running very very slow when the projector has completed it's lamp cool down routine.
The reason for this is that a portion of the switching power supply remains energized (running) when the projector is at rest. But as I mentioned it should run very slow in this state. If it remains running full blast then most likely the fan speed control chip is shorted which can cause fail 2 ways, either the fan 1. runs full
speed or 2. remains stalled (then the projector will go over-temp and shut itself down) I hope this answers you question.

Cheers

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.
