Saying lens cap on won't record!


Your iris stuck up contaminated by the grease of lens mechanism. To clean, the unit must be opened up to where you can access the lens assembly and remove the iris unit assy then the two curtain(shutter) and clean with video head cleaning solution or any alcohol base cleaning agent. Re-assemble it but test the shutter first before assembling the camera completely. To test, open the shutter(curtain) manually by your finger and must close freely once released. Also clean the surroundings for some oil near the iris unit to avoid it from coming back to the shutter.. Good Luck

Whiteout on fujifilm f20. how do I remove the lens?


Firstly, to isolate the shutter as the problem, turn the camera on and the flash off. put the lens into full optical (not digital) zoom. Then turn the camera lens to face you and look at the lens and take a picture.
With the camera in full optical zoom the shutter assembly will be right up to the outer lens so you can see it clearly. When the button is pressed you should see the shutter fire across the lens inside. It should cover the lens completely. If it does not or doesn't fire at all then you get over exposed pictures or lines across the photo. The most likely cause for this is moisture residue on the shutter leafs sticking them together.
To clean you will need to strip the lens down almost completely to access the shutter assembly. If this model of camera uses a sealed shutter unit then it will be impossible to clean. The only models i have found so far that use a sealed unit are the F460 and F470. Yours I am not sure of as I haven't opened 1 up but the solution for most is to strip it down and clean.
Tip: use another camera to photograph each stage to help on re assembly

Viewing screen is completely blank and will not take pictures


A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open).

To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

Lines on screen and photos, too bright photos outside


Lines across your pictures or pictures too bright are due to the shutter not closing correctly or at all.
to check this- turn camera on, turn off flash, turn camera around and look into the lens. Adjust the zoom so that the shutter and internal lens comes up to the end of the lens and whatch as you take a picture. You should see the shutter close completely over the lens. If it doesn't move or does not close over completely then there is your problem.
If camera was dropped it could have jammed the shutter open or obstructed it in some way from closing completely.
camera will require repair/ service.
You may have some luck if you power up and down your camera numerous times before taking a picture. The action of the lens opening and closing may free the shutter.

Automatic lens cover won't open


Hi,
Do you mean the shutters which protect the lens? If this is the case, are you able to carefully open them by hand? If so, there is a chance that a bit of dirt is preventing the shutters from opening. You might be able to get rid of the dirt by carefully sliding a bit of paper (I find yellow post-it notes perfect for this) in between the shutter and inside of the lens to shift the possible dirt. Also, you can try putting a minute drop of isopropyl alcohol (used in lens cleaning fluid) in between the shutters and the lens assembly so the possible dirt dissolves - then try to carefully open the shutters by hand. I don't recommend using any other alcohol/liquid for that.

Other than that, it's an absolute pain to get to the shutters to fix them properly on TZ3. Basically, the lens would need to be almost completely stripped-guide to do that would be beyond the scope of this site :)

Good luck,
Raf

Shutter not opening on canon powershot s40. screen is blank & images are black


Does the lens have a physical shutter that you can see, like metal petals that open and close? On my camera, the aperature is made of petals that open and close to regulate the light and they close down completely when the camera is not in use. The petals are controlled by a small servo that, if non-functional, will completely "blind" the camera CCD. Many cameras use electronic shutters that have no mechanics and that would indicate a hardware problem that most likely cant be fixed without a new PC board or lens/CCD assembly..

Shutter doesnot open completely


Are you talking about the shutter, or the lens hood/flap on the exterior end of the lens?
If you are referring to the shutter, yes the other solution would be correct. But in doing that you will will spend more than you did for the camera itself. It is NOT a free repair!
If you are referring to the exterior lens cover, I have have the same issue with my A530 & have found that I just need to lightly brush the flap back with a fingertip & it will open. It is a hassle, but the alternative is again to spend money, and lose the camera to to shop for several weeks. So I deal with the minor hassle.

Lower half of photos dadrk when printed


Set camera to B , open back door and release the shutter and keep it open while you inspect focal plain area. Is the shutter fully opened ? If you release again is the shutter opening completely and closing completely ? While the shutter is fully opened on B look through the shutter/ mirror box area is anything obstracting your view ? Seems like one of the shutter curtains is not opening properly and shutter will need servicing. Please note that it may not be economical to repair : $ 150-200 if the shutter block does not have to be replaced completely.
