Infocus x1a projector shuts down after 30 seconds - dust problem ??

I have an Infocus x1a Projector that is only three years old. I had to replace the first lamp after 1 year and about 1500hrs and now the projector will turn on but after about 30 to 45 seconds it shuts itself off - leaving me with three blinking red lights. The lamp only has 1200hrs on it and is two years old. Is there any way to open the projector up to see if there is dust inside the machine. We regularly clean the lamp but were wondering if there could be excess dust inside the machine which is making it shut down. We would like to try to fix the problem before the globe blows. Hope you can help. Thanks Julie

Most likely, if it is a thermal problem, your main cooling fan has quit or is stopping after a short period. The problem is, I've seen several of these do this, and in every case, it is not the fan that has failed, but the Controller Board. And that is a very expensive part.

There is a safety themostat inside the unit (looks like a silver button the approx size of a dime) that will shut the system down if you do not have adequate airflow. You can dis-assemble the projector by removing the screws on the bottom and rear of the housing and pressing in the plastic locking tabs inside the cover all around the perimeter but I would advise against this unless you are comfortable with delicate nature of the projector.

Lamp burned out on X1 infocus projector, Replaced lamp, new lamp stopped working in about 5 hours, got another new lamp and it does not light at all. Still blinking 3 red blinks(saying the bulb is bad)


make sure the colorwheel is spinning. if it is not, replace it. also, blow the dust out of it with canned air. excessive dust kills lamps quickly. you'll also need to reset the lamp timer. are you using an sp-lamp-009? the sp-lamp-018 looks exactly like it, but is used in th x1a and x2. the x1 only uses the sp-lamp-009. if all else fails, replace the power supply.

Projector turns on for about 30 seconds then shuts down. the fan kicks up high, and led light flashes yellow for about 4 min until the fan shuts off. does not feel hot so overheating does not seem to be...


if the lamp lights and then shuts down, replace the lamp. it's at the end of it's life. to rule out overheating, blow the projector out with canned air. dust retains the heat that the projector is trying to expell. also see if all of the fans are working. if you do get an image for a short time, try to get into the menu to reset the settings to factory default. lastly, if all else fails, you have a ballast issue. unfortunately, infocus no longer sells parts for this model.

I have the same problem as someone else has posted on this site. When I start up the projector, x1a, it goes directly to a faint white screen without any button response. With or without a video source...


replace the colorwheel. part # 525-0144-00. you can get it through av solutions in ny. www.avsolutionsny.com it's not that difficult to replace, but if you are unsure about it, you can send it it to them to repair as well. they are an infocus service center.

My bulb went out in my x1a so i replaced it now it


is the led on the top of the projector blinkng at all? if there is no led lit, the fuse on the power supply may be blown or the power supply itself needs replacing. turn the projector on. you should hear the fans and a high-pitched whir. if you don't hear that whir or it sounds like a noisy motor, the colorwheel needs replacing. if it sounds good but no light, make sure you have the correct lamp. the x1a takes the sp-lamp-009 lamp. it should have 2 white wires, each at opposite ends of the plug. if you have a lamp with a red wire and a white wire, you have a lamp for an x2. also make sure the lamp door is closed completely. if the door is closed (hitting the switch), the lamp is correct, the led is green, and the sounds are good and it still does not light, the ballast is bad and needs replacing.

High pitch noise from the projector and is not from the fans


it's the colorwheel. if you have an infocus x1a, it is a dlp projector and has a colorwheel and dmd chip instead of 3 lcd panels. the colorwheel spins to allow the lamp to stike. it should make a slight high-pitched squeal. if it's too loud, the motor is shot and needs replacing.

Infocus x1a projector shuts down after 30 seconds - dust problem ??


do you have the correct lamp? the x1a takes an sp-lamp-009, that has 2 white wires, and not the more common sp-lamp-018 which looks exactly the same except has one white and one red wire (and are in different plug positions). if it still doesn't light, there is another issue (possibly the colorwheel) along with the lamp timer reset.

Infocus x1a shuts down after 5 minutes


3 red flashing is a lamp error, not the fans. the lamp has a problem striking. make sure it's pushed in and plugged in all the way. if the lamp is not that old, the power supply needs replacing.

Infocus LP820 - Turns on for 30sec then shuts down


This could be one of two problems I have seen with another model Infocus projector (they are very good projectors though)

The first is the video input. Make sure it is attached correctly at both ends of the cable.
The second, remove the dust covers and blow them out. The problem can arrise if the temperature sensor detects the air inside the unit is getting too hot. If you can see the sensor when the dust covers are off (it will look like a little lump of goo on the end of a wire) then just give it a wipe as well. If dust settles on those it can cause incorrect temps to be reported.

Hope that solves your poblem =)

Con: Infocus x1 and infocus x1a projector


Hi there

You could most probably do that yes , it's normally only the Mainboard that is different.
