I have an Infocus DLP X2 projector and the lamp is not firing. The unit powers on and the fan runs but the green power light eventually turns to a single blinking red light (service manual says this means to check the lamp housing). There is no picture from the bulb. I have replaced the lamp with one that I know works in order to check the housing and lamp but it still doesn't work (doing the same thing as before). Any ideas?
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.

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.
Power Supply problem. Check for "Bulged" capacitors in the output circuit ( 5 parts 470uf @ 16VDC). Also an indication of this problem is to remove the lamp cover and plug in the AC power cord. If the fans run slow....this is the problem.
Hi, did you remember to reset your lamp timer after replacing the lamp? You can learn how to reset it on this LINK.... If after resetting, the light still remains green, then it's either the color wheel motor is not getting up to speed to sync with the dmd chip, the wheel sensor is going, or the power supply needs replacing. you can try to replace them yourself or send it to an infocus authorized service center....
This could be one of 2 things. It could have a bad color wheel or there is a setting problem in the unit. If the video mode is not set correctly like NTS or PAL it can give a black and white image.
The other could be your color wheel has failed. Did the unit make any noises before the color went out?
Some times the color wheels will make noises when the age before they crack or break from the heat.
I believen you can pull the lamp out and with the lamp out try and power the unit up, look into the little hole the lamp shines into and see the color wheel spinning. when you first plug it in and unplug it the wheel should spin and you should see the colors change. DONT TOUCH THE COLOR WHEEL they are fragile and can break easy. Some get more brittle over time from the heat of the lamp.
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!
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.
if the lamp is new, it could be the power supply (the ballast is built in to the ps). but make sure you have the right lamp. the X1 and X1a have an sp-lamp-019 and the similar X2 and X3 have an sp-lamp-018. the lamps are almost identical except for the wire configuration on the lamp plug. make sure the wires in the plug match the positions in the socket. also, when you turn it on, if you don't hear a high pitch squeal, the colorwheel is not working. and if that isn't working, the lamp won't either. also check to see if the lamp door is closing properly and hitting the switch at the top of the opening.
