My benQ bp2 120 micro seris projector keeps turning off

One of two issues. One, the unit keep overheating. Common even with my projector. These things should be serviced and cleaned as dust clogs intakes, fans and exhaust ports. Proper venting is essential. If you have the ability, take the unit apart and use compressed air to blow off all circuits, vents and generally all around. Do NOT use high pressure...just the blow off cans will work fine. Second, the lamp could be on it's way out. Check the hours on the lamp counter. Generally, a lamp life that states it is good for 2,000 hours will last about 1,500 as turning the unit on an off eats lamp life.

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.

My lamp is working but everything is black and white

Play about with options, there might be a option to change the colour scheme. Might be under Colour tone.

Projector produces very low light.

My recommendation is that since you have 2 of these machines and the other is working fine,

Pull out the lamp from the good one and place it in the faulty one.

Turn it on and check the projection quality if it is still blurry. If it is working good, then replace the lamp. If it is still blurry, a good cleaning to the lens on the projector may be a good idea.

You can also check the auto focus function of the projector and the cable that provides the video signal to the projector

You can get the manual from below link if you need to find out how to check the auto focus setting

I heard a pop and now the projector only shows black and white.

The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.

If you're getting a black and white image with or without source, it's probably the color wheel. Do you hear anything loose inside the projector? if you do it's the glass fragments of the broken color wheel.

Projector only displays Black and White / No color images.

The problem is the color wheel. It may have broken or motor stopped on clear. Either way the image will remain unchanged just without color. It will need to be sent in for service. Not an unusual problem for BENQ. I have had 3 that have come apart after making a loud whirring sound. Good luck getting someone with BENQ to help they are horrible when it comes to service. Buyers beware!!!
