On the SLVR, the lens is on the back of the camera. Lately, when I've tried to take pictures, they've been really grainy and hard to focus. I noticed that the lens has some sort of dirt or dust or something on it, but it's under the top glass. How do I fix this, or clean it?
Remove back cover. Once removed you will see four screws they need to be removed using a T6 screwdriver. After removing the screws carefully remove the panel. Turn the panel over and clean the inside of the lens cover. Use either a soft bristled brush or a lens cloth to clean. After cleaning reassemble and test it out.

i suggest you take the camera to a digital Canon repair shop and ask them for a repair quote. They may charge for a quote unless you go ahead with the repair, then you can decide whether to get a new body or get it repaired.
Jim, I really wouldn't recommend this. It requires extreme patience and meticulous parts tracking. Note that junctions stated: "It's really hard to take apart,", and he ain't kidding. Really recommend that you return to the remedies that you had been trying. Sometimes it requires many repeated tries to free the gunk from the shutter. I've found that for the smaller pocket cameras that the most effective solution seems to be extending the lens and tapping around the lens barrel with a pen/pencil. Then alternately opening the battery door with the camera turned on (no need to play with shutter modes). Then just alternate with tapping, battery door, tapping, battery door, and keep doing this until the shutter opens/closes. Once this happens, set the camera to continuous shutter mode and snap off about 100 pictures to final lubricate the shutter.Good Luck,t00nz aka CR
Your pictures should not be looking grainy. Are they printed grainy but look clear on your screen. If so then it's just your printer. Try forcing the flash in the highest resolution. If you video's are grainy too then there is possibly something wrong with your camera. Make sure your lens is really clean. Worst case your CCD sensor inside your camera could be bad. Hope not!
The problem is that the lens has become stuck in the barrel
after dropping it. There are some DIY solutions you could try, but the
probability is that you will have to get it fixed by a professional.
these at own risk as it may further damage the camera.
try connecting your ac adapter or usb cable.
Try holding the
shutter button while switching on the camera.
Look at the lens ,
and if some of the lens 'circles' is misaligned or not concentric then
try wiggling it (while holding camera lens down).
pushing or pulling the lens when it extends but this is risky as it may
cause the lens barrel to slip out of its guidance system.
way to do this is to place the camera lens down on a hard surface and
then power it up. Be sure to use a soft cloth or something similar as to
not scratch your lens or casing. Let the lens push the camera up and
down a few times and sometimes the little resistance provided by the
camera is enough to get things going again.
Try hitting your

Other than that , I would take the camera to a repair
center for a evaluation to see if it would cost more to repair than to
replace the camera.
If it is still under warranty I would suggest
you take it in before trying any of these steps and remove any
off-brand batteries or accessories as some stores are really fussy about
warranty repairs on camera's with non-brand accessories.
paulc846, There might just be a smudge or fingerprint on the lens, that's enough to cause that to happen to the center of an image. Get some lens cloth on a q-tip and try to gently wipe it clean. If the image is really grainy and the camera has recently been dropped the sensor is damaged. Let's hope for the smudge. randy320sgi
It sounds like the aperture is getting set very high. If the aperture is a high number, the lens opening is very small which lets less light in and would cause a dark image. This would also show any dust that is in or on the lens or image sensor. The dust doesn't usually show on apertures with a larger opening (smaller number). Make sure your aperture is being set to a reasonable number, probably no higher than 8 or so.
As simple as this may sound, have you cleaned the lens lately? A lot of image quality deterioration comes from a finger print or other smudge on the lens. Digital cameras are succeptable to even the smallest gunk on the lens. Because the lens element is very tiny, use a cotton swab with a drop of lens cleaner (or isopropyl alcohol) to thouroughly clean and dry the lens. If it isn't a dirty lens, check your file-size and flash settings.
here are some tips that may be the reason why you are having those blurry, grainy and yellowish pics.
It is important to keep your lens away from excessive heat (i.e., hot car in summertime or a heat source in a home). This will help prevent the greases, used in most lens barrels, from breaking down into an oil that can run inside your lens and cause overexposure by slowing down the diaphragm.
Use rear element lens caps on your lenses when they are not on the body. Wide angle lenses, by design, have rear elements that extend out farther then the lens barrel and are susceptible to wear, which can ruin sharpness.
Always use a filter or lens shade (hood) to protect the front element.
Never, ever, oil your lens. A minute amount of oil on the diaphragm blades will cause them to operate slowly.
