Infocus lamp not firing

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.

I have two dlp infocus X2 projectors. Both of them have lost their color. Is there something I can do to fix it?


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.

Lamp replacement issue infocus in24+


either the lamp's seams aren't taped over with foil tape to prevent the premature shutdown due to the heat sensors being triggered, or the fan under the the colorwheel has stopped, maybe due to a piece of lamp from a previous lamp explosion being stuck in it, or the power supply/ballast is bad, or the eca on the engine itself is bad. The lamp is the easiest to try first. There should be foil tape over the seam on the side of the lamp you can't see when it is installed. If this doesn't work, take the front bezel off amd get where you can see the fan under the colorwheel and tunnel and power the unit up and see if the fan comes on. If it does thenthe eca on the engine or the power supply ballast is most likely bad and these are major repairs.

Infocus lp420 powers on (can hear sound) but no


if you get no leds, it's the power supply. if you get fans, it may be the colorwheel. if the colorwheel is ok, it's the ballast.

InFocus LP725 light goes out after 10 minutes


The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help
