push the button like you are trying to put your finger thru the top. if that fails you can push the button and try to pry it loose with a flathead but you run the risk of stripping the teeth on the leg. those are your only options unless you want to take it apart so you can see the mechanism and try and figure out the problem that way.

I strongly advise against opening a lens for any reason. You may not be able to put it back together!

For cleaning the outside surfaces of lenses, lens tissue and lens cleaning fluid is fine. Both are available at camera shops. The fine camel-hair brush and air-blower-squeezer combo also works great.

Number one rule in lenses: don't clean them unless you have to. A little dust is far less trouble than a scratch! And keep those fingers away. Skin oils are murder on both plastic and glass.

if it has no signs of life at all it is the power supply, another tell tell sign is if you look at the lamp and see bubbles in the mirrored part of the lamp.

oh, yes. if the lamp works and the colorwheel spins, that's all there is.

the light tunnel is collapsing. you can purchase the part from, or send the projector in to, an infocus authorized service center. try av solutions in ny. they're pretty good.

if you do chose to do it on your own, buy the part (315-0053-01). the tunnel is a rectangular mirrored tube located under the colorwheel between the lamp and the lens.

This is a problem with the feflector, and is quite common. It was probably moved or bashed whilst in transit, and can only be repaired by a professional.

I really doubt you'll find a generic power supply for this unit. I can repair this power supply for you at a low cost. I repair power supplies. My ebay ID is Gtitubro

does your projector detect on ur machine !. your machine recoganize it or not !. ensure the vga cable is ok.if everything is ok then if you can open the projector then check the power unit inside and the voltages applied to the processing unit. this is sometimes due to low voltage or power supply problem.the lamp and controller unit are different from each other. there must be a switiching problem inside. if you can open it then well n gud otherwise u have to take it to the service centre......

may be the mirror could be out of alignment, but due to hot beam the inside lamp burns the dust inside and outside because in running mode it's too hot. I think u must take it to the good service centre to clean it fromboth side. same as scanners.Also check the mirrors, they are not changing colour, if u are using it to much.
best of luck...

lamps are affected by strikes. each strike erodes a part of the anode. so in essence, the lamp wears out. However a Xenon has a much longer hour life as once it is running, it cares "relatively" little about how long. SO for commercial units, this is an advantage. there are also larger potential issues about colour stability over life.

with UHP, they care only minimally about strikes, it really is not even a strike, so while frequent on and off can kill it early, with normal usage, you are going to be fine. However with a UHP, if a lamp runs for longer times... then you have issues. THe way i had it explained to me was as such;
With a UHP, it gets up to proper operating temp in about 5 mins. once it is there... it SLOOWWWLLLLLYYYYY continues to heat up. After about 2-3 hours, it starts going outside the nominal operating range. once it does so, it starts to degrade the lamp. thereby lowering life expectancy. if you shut it off after about two hours or so and let it cool for ten mins then do it again for two hours... you are in a much better place. In a grand scheme, apparently if you run the proj for an average of 4-6 hours every time, then expected lamp life goes to about 50%. THis is very rough and in a general sense so just take it as general guidelines.


Lamp life for a projector will vary based on many factors including application, installation, intake of cool air and exhaust of hot air, usage, and proper maintenance. Heat buildup can reduce lamp life and even damage your projector. Here are some tips to help your projector lamps last longer.

Once you turn on your projector, wait at least five minutes before turning it off to allow the fan to properly cool the unit. After the fan has cooled your projector, you may unplug it and store it as desired.

Do not obstruct the air intake or exhaust vent. Paper should not be placed on top of a projector, or where vents are located.
Keep the exhaust vent at least two feet from any object.

If the projector is built into a compartment, wall, ceiling or shelf mount, the minimum distance requirement (usually at least two feet) stated in your owners manual must be maintained.

Clean the projector's air intake filter every three to six months -- or more frequently -- based on your operating environment.

Do not move your projector until the lamp has cooled (about five minutes).

Run your projector for two weeks and/or 20 hours shortly after your purchase. If the lamp is going to fail, it will usually occur within the first ten hours of operation. Lamp warranties typically last just 90-180 days from the date of purchase, rather than the first installation.

When you purchase a replacement lamp for your projector, remove the existing lamp and use the old lamp as your spare. If your projector is new, test the original lamp for the two weeks/20 hours before removing and storing as a spare.

I hope the info. which i have given you solves ur problem if not i am sad to say you have to get it repaired..

change the solution on you macbook

Several things to check.
Make sure both the input selection on the projector is for PC and make sure the PC output selection is for the external output, as in an external monitor. The PC does not care or need to know that the external output is a monitor or projector.
If none of these works, try a different cable and output on both the laptop and projector ie, Switch from PC output to a DVI or HDMI.
