I sugest you use compressed air and blow carefull in the projector.
Take out the new lamp and remove the topshell before using the copressed air. If that dosent help i recomend you to let a pro clean the lenses inside. Its not that easy to do that yourself, they are quite smal and fragile and its very easy to damage them if you doing it wrong.

Good luck to you M8

You need to clean the mirrors inside your projector, you can either open the shell and use compressed air,to clean it
If you are going use compressed air, make sure you dont ever hold it near the mirrors.but you can can also give to a professional to clean if you cant clean it Its cheap to clean a projector by a pro, it takes a pro about 10-15 minits to do it.

    if after cleaning and the problem still persists then You probably have a polarizer failing on one of the LCD panels inside.

    There are 3 of these in LCD projectors, red, green, and blue. They all
    get the light fed into them, that light is then combined and fed
    through the projection lens.

    this few steps gives you an idea on How to clean the unit;



    1. Underside of the projector. you can find the filter under the hatch on the left side, lamp is under the hatch on the right rear.de of the projector.

    2. Filter hatch opened and fan bracket removed. Filter is gray foam in lower left. Clean the filter with canned air or wash and dry thouroughly before replacing.

    3. Clean the projecter using a canned air.

    4. Hold the unit vertically to avoid any liquid get inside of the parts

    5. On the LCD and polarizer area. You've got to blow out all the crevices in this area, using care not to scratch or dislocate anything.

    All done!

More then cleaning the lenses , you will need to reassemble them, or replace them.

Looks like the lens assembly is out of place or damaged, the lens assemby should be taken apart and re-mounted.

Call the phone number listed on the owner manual to get a replacement lens instead.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

I just replaced bulb with new and after a day there is a dark spot on the screen


I have the same TV - I have a dark spot in the upper left hand corner. I have always thought this TV was dark. Be sure to get OME lamp. Cheaper ones are not worth it and can damage your TV more.
dlplampsource,com--Just a note if this ever happens to you. TV would not come on in the AM-Had no picture, but had sound. It was not the lamp, but the safety switch. It's blue and at the bottom of the lamp housing. As soon as I flipped it and replaced the back cover, the TV came on.

We purchased a sony wega hd lcd projection tv. The set had a great picture until the lamp had to be replaced. The screen got progressively darker until the screen went completely dark. After the lamp...


It sounds to me like you got a fingerprint on the lamp when you installed it. The oils in your skin can cause all kinds of problems on a lamp that gets soo hot. I recommend replacing the lamp again and using a tissue or sterile glove to hadle the new bulb. Also, before replacing the lamp make sure to clean and vacuum out the light engine box and fan.

If the problem persists, then the LCD panels inside the light engine have been heat damaged. There is a class action lawsuit in New York that is trying to extend the light engine warrantee on Wega TVs. You should give Sony a call at 1-800-222-SONY for information and more assistance.

good luck!

X2 OHP mounted on ceiling fixture. Image is dark on right side


Yes it will have to come off the ceiling. It sounds like the light tunnel has collasped. This is located under the colorwheel. If you can get a new tunnel , be careful removing the colorwheel so no segments break off of it...make sure the new tunnel is pushed against the "lip" before screwing the tunnel clip back into place.

Dark spot issue.


Its an acrylic condensing lens inside the light engine that has melted/warped. You have to pullout the entire light engine then disassemble the optical light tunnel to get too the lens. Then you need a lens-smith to cut a new lens because Infocus won't stand behind this design flaw. Its really a shame on Infocus!

Have two dark smudges on screen


Dear Chaplink,

You said "two dark smudges on monitor screen".

Asumming that these smudges are digital and not just something tata you can remove with cleaner, If your moniter is back-projecting then the issue is probably that the projector has been damaged.

If your monitor is a flat-screen then the gels inside of it are misplaced from somone touching and damaging your screen.

So basically, the only practical thing you can do is buy a new monitor.

The image is not transferring properly..........

remove and clean all corona wires (thin wires that create the latent image) use a q tip and dip in rubbing alcoholhot

Also make sure the fuser rollers are hot(insert or trick safety switches to determine if the fuser lamps are lighting usually upper and lower

Also check the imaging lamp to be sure it does not have any dark burn marks on it and clean the mirrors and the glass under the coy area

Optoma HD72 displays white circles when the picture is dark


Have your projector professionally cleaned. It is dust in the inside optics. You should not attempt unless you are very skilled. if you are going to do this yourself have a lot of compressed air on hand.
