The lens of the camera will not close completely. What do i do?

Get canned air and gently blow on diaphragm while opening and closing.

The lens is damaged and needs to be replaced. Sometimes with use or maybe an accidental hit to the lens can cause a malfunction to the camera resulting in that error. Also if you for example took the camera to the beach, getting something like sand in the camera can jam up the lens and prevent it from fully extending or retracting.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mike_005777b2fc6bfc30

You have broken last (black) gear in opening/closing mechanism. Common problem. Need new gear or fix missing "tooth".

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.

to open them completely simply push them with your finger. try doing so also when closing them. i have the same issue sometimes.

Maybe the lens is stuck.

I hate to say it but your camera needs to be serviced. Might not be worth the repair. Try to take it to a local repair center that would offer you a free estimate....

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..

Buy the next camera- at 3 years old no economic repair will be feasible- but you could play with it some I guess

Follow the steps below to troubleshoot if the lens will not open, retract, or extend. WARNING: There is a risk of hardware damage. Do not attempt to manually force the lens in or out. Doing so may damage the camera. NOTE: Because each of these steps represents a possible solution to this issue, check the camera status after completing each step. Ensure the battery is adequately charged or connect the AC power adapter (if applicable). Perform a power reset. If the camera lens is still not operating correctly after completing the troubleshooting steps suggested, service will be required. Hope this helps
