Not really, but I'd make sure that the mirror is spotless. Take the time to do it right.

My casio exilim camera captures images and save it blurred, seems like the lens is affected pls what can I do


No model? please make sure your lens is switched to auto focus (AF)
When the lens is smudged, please only clean it with fluid special for lenses. Never use normal glass cleaners, because lenses do have coatings that come of easy with normal house hold cleanres. If you already tried cleaning the lens that way, I think we have found what is wrong. Without the coating the lens can't give good pictures.

I have a hitachi 55vf820 lcd rear projection tv. How do you get the cover off to clean mirror?


Don't try that as the mirror almost never needs cleaning and MUST be cleaned with a special cleaner---leave a single fingerprint on that mirror (or a smudge) and it will stand out in the picture like a sore thumb.

My pictures all come out with a smudge depending on the focus is howm noticeable it comes out on the image


This is almost certainly due to dirt on your lens or mirror - possibly your sensor. If you have two interchangable lenses try them both and see if there is a difference. If no difference the mirror or sensor is probably dirty. In either case, I would suggest you have them cleaned professionally unless you are confident about working inside your camera. If there is no smudge with one lens then the other lens must be dirty. Clean both ends carefully with soft, lint free cloth.

Please help on cleaning the mirrors


It is not recommended...not even for a service tech unless there is a definite need.

I think some people think that this affect the picture brightness and cleaning it will help. I can tell you that after 3000+ units(not an exageration) this does not need to be done and it is never the reason for the dim picture.

You are more likely to leave smudges then remove any. In some cases you may get spider webs or large pieces of dust inside but it is best to just vaccum or blow these specific items out. You can look inside 90% of these projection TVs and it is enough dust floating to look like a blizzard. You can not get rid of it and it really has no affect on the picture quality

Basically, I dont' recommend cleaning by anyone. If you do, just lightly dust or blow out with compressed are while vacumming the floating debris.

Smudge mark 2-in wide down right side of each sheet of paper.


Generally speaking, any area that is darkened, is receiving less light. This can come from a lamp that is failing (similar to a fluorescent lamp used for lighting developing a dark end) or a mirror or optical lense that is contaminated with toner.
This may require some disassembly to diagnose and cure.
You may also want to visually check the fuser assembly (often accessible behind a door) to ensure there is no toner buildup on the affected side.

Pentax ME super dirty mirror


Don't even think about cleaning the mirror in your SLR. For smudges and marks that can't be blown away with a handheld blower, you really need to have it cleaned by a repair shop. Most technicians clean mirrors with a special viscous fluid specially formulated to protect the fragile surface of the mirrors. Definitely do not attempt it with a standard lens cleaning solution or cloth as you could cause irreparable damage.

Keep in mind that this will not require disassembly of the camera, so the charge should be nominal

Smudge looking marks onscreen


If you suddenly noticed it, this is most likely caused by a large piece of dust on the lens. It is hard to clean, you would need to take the whole TV apart in order to get to the lens (mounted on the optical block).

It could also be caused by a failure of the optical block, which had inherent issues. There is a pending class action law suit against Sony for problems with optical block that include smudges, hazes, and tints that appear after a certain number of hours.

Other causes could be a dirty portion of the mirror or a smudge on the inside part of the screen but these are rare because dust and contaminants do not usually accumulate on these parts of the TV.

Need to clean mirror or lens


The particel or hair is probably on the IR filter glass that sits over the sensor. You could try puting the shutter on bulb. If you then remove the lens and hold the shutter release you will be able to see the filter glass and possibly be able to remove the particle with a blst of compressed air. Do this in a cleanish room or you will make things worse.
