Need to clean mirror or lens

Two things to look at from rear with back off: one is the inside of the screen and or the large mirror in rear of unit--do not touch mirror.

second is the unit has a small lens (2-3 inches) the points up towards the mirror---dust or such on it will cause this--it can be cleaned with a lens cloth.

If the mirror has this (uncommon) the entire front of set would have to be removed (screen units) and that is not real easy.

If lens and mirror and screen are ok problem is INSIDE the optical unit that the lens is part of---on rare occasions that can be cleaned out with compressed air.

without seeing a photo of what it looks like this is all I can suggest.

Hiit is simple dust particles. I can let you know by very simple tip. But unfortunately I can not describe in word everything. First thing you can try is that you can you ear know remover or squeeze blower. Set the camera at ccd cleaning mode.(not auto mode) See front inside of mirror box when mirror goes up, you can recognize the brown spot. Blow with the blower. Other method is I can not expain everything.

If this is a fixed lens camera (you didn't give a model) I'd suggest strongly for you not to attempt to take it apart. Hopefully what you are experiencing is dirt on the outside of the lens. If so turn on the camera huff (breath) on the lens to create a slight amount of moisture and then use a lens cleaning tissue to gently clean the lens.

If as you say this dirt is on the inside then I would suggest getting it cleaned by a camera repair facility. Problem there is a lot of these point and shoot cameras cost more to clean and fix then it does to just go get another one.

Next thing if the inside is dirty they you must have a lot of lint in your pockets or you have been using this camera in a dusty environment. For carrying it would be best in an actual camera case rather then an open pocket and for dusty condition I've used shallow water camera bags and I've also used ZipLock bags while photographing a waterfall.

Yes, you can clean. Not as complex as I originally thought.
1) Remove all of the silver screws
2) Separate the silver case (should split in 2)
3) Remove the 3 black screws in the middle
4) remove the center square cover that is over the lens
5) Use a duster spray to clean the lense and mirror
6) Reassemble in reverse order
Not knowing what I was going to get in, the entire process only took about 7-10 minutes.

Same problem with mine.
Any solutions out there?

Because of age of use, dust covers the PRT lens (Red, Green and Blue) and Mirror as well. You can clean them with a soft cloth, with care. It is easier if you can remove the Screen (front side) but it is kind of complicated. The easier option in most of the Rear Projection TVs is to remove the lower cover and check if you have access to Lens and Mirror. Avoid excessive pressure in lens and specially with the mirror while cleaning is made. This process can make the picture clearer, specially if dust is excessive.

You must have dusty mirror box area. Here is what you should do. 1. Remove lens from the body. 2. Blow out any dust from the mirror box area using can duster (careful not to spew out liquid). 3. go to menu and select mirror up or ccd clean mode. You can also set at manual shutter speed "B" and hold up the mirror. 4. Blow out dusts over the CCD sensor (Do Not Use can air! If any liquid sprayed on CCD the cleaning gets worse) so use Hand-squeezee air bulb. You can purchase one from any camera stores.) 5. test shots and repeat. 6. If this procedure did not resolve the removal of the dust, you can purchase a cleaning solution package and try it. I do not recommend it becasue our techs get lots of cleaning requests from these package. Remember, if you are using these solution, 1. Never give any pressure to the screen, just tissuie touch pressure only. 2. move circular motion as you mouth blow the air as you move. complete the motion exiting through the corner of the screen. Did not work? send it to repair techinician! Our tech cleans it for $49. 24 hour turn around and also checks the camera too. Good Luck

The view finder and focusing screen are separate from the CCD sensor. The mirror reflects the image to the view finder until you take a picture. Then the mirror goes up, the shutter opens to expose the CCD to capture the image.

If you have a lot of dust, you should look into a cleaning kit, or have it professionally cleaned. This will show up on your images as white and/or black specks.

I have an Optoma EzPro 737 DLP projector that accumulated dust inside the lens and for ages I couldn't figure out how to get rid of it. It cast shadows onto the picture and scattered light outside the edges of the picture. I thought I'd have to dismantle the whole lens assembly (then realised that this is virtually impossible without being an expert). I then stumbled upon a little black rubbery plastic panel on the side of the light path, which unclips. I then realised that the dust had built up on the lens that sits in front of the DMD chip (the thing that makes the picture).

Here's what I did, with the case open and having vaccuumed out all the dusty parts of the projector to avoid making the situation worse:
- Took off the little rubbery panel,
- Removed the lamp from the projector and placed a flashlight inside, shining into the light path (or a mirror directing light from a table lamp above)
- Looking directly into the lens from close up, you should be able to see the particles of dust stuck to the inner lens (with a nice magnified view)
- First tried blowing air into the gap on the side of the light path (I used a balloon pump).
- Next, I poked a piece of thick nylon fishing line into the hole so that it could touch the surface of the inner lens.
- While looking into the lens, I could see the tip of the nylon, then directed it to the largest dust particles and used it to scrape them off (nylon is much softer than glass, so won't scratch the lens).
- This was quite time consuming but I got rid of the most obvious bits.

I'm not sure how different this would be for another model of projector - but I hope it helps!

That's odd. I had the 707 (may she rest in God's eternal peace), and never thought that dust could get behind the lens. Do you see the dust when you look through the EVF, or when you look at the lens itself? Either way, one way to test it is to set the camera to the smallest aperture (f/8), infinity focus, and shoot a clear blue sky. Open the picture in your editor program, and see if the dust shows up. That's a technique to use with an SLR to see if the dust inside would affect a picture, so I'm not sure if this will work with the 707.
