Lens motor The lens motor on my Cyber-shot will no longer work. The motor seems to run but the lens will not move in or out and the lens cover doesn't close. It doesn't matter if the batteries are new of not. Do I need to replace camera or how do I fix the lens.

1 Answer



Check the gear box, maybe one of them is broken. Look carefully every gear this is a very common problem in this camera

Spilled soda on my camera sticky lens

Buy lens cleaner, to wipe off what you can, but in truth the lens should be dis-mantled to clean it properly not to mention the rest of the camera.

Dsc-P52 lens cover sticking

You need to go in and physically open the lens cover.
1. take out batteries 2. remove memory card + the small phillips screw.
3. remove the 3 remaining exterior screws. carefully with a small flat tip screwdriver pry the plastic halves slowly. eventually they will come apart. 4. at the bottom remove the small ribbon cable. 5. disconnect the mini motor wire, black and red. 6. unscrew the motor drive for the lens cover and then open the lens. 7. purchase a new lens cover motor. 8. If your screen still says turn off , then press menu and delete some files. good luck ! Work Slowly and carefully and ground your hands to a pipe somewhere before working on the unit. the static electricity could ruin the circuits !


Sony cyber-shot dsc-w570 lens cover won't close

Lens block is faulty you must replace it with a new one

Sony Cyber-Shot 8.1 - when I turn the camera on the lens moves in and out several times and then it says to turn the power off and on again. Help

There is probably no user solution, it seems that optical lens block is wrong/damaged, the only solution is to replace it.

Lens no longer expands

easy method from the front of camera:
unstick ring "Carl Zeiss Vario-Tessar 2,7 et."
unscrew the 3 silver bolt
remove rubber ring
unscrew 3 black bolt
with carefully remove lens, watchful cooper washer 3 x 3 pieces
blow with blow-pipe (rubber pear) about a side-wall of objective
to remove dirt from slideway.

enjoy success

My camera sony cyber-shot dsc-h2 does not switch on when the button is pressed. please suggest solution

I had the same problem.
In another post on this site I read that a stuck lens or bad batteries can cause this. My batteries were OK and it seemed as if the motor or lens gear was stuck.
The shutter could still be opened and closed by pushing power while the lens cap button was either pressed or released.
As I could not move the lens and some soft "shocks" did not release it, I once again disassembled the whole camera. (5th time the last two days...)

Note that for my camera there seems to be some protection mode being activated after a few unsuccessful tries to power up the camera with the lens cap removed.
After this protection was active it was not possible anymore to even display anything until disassembling the camera and pulling some of those internal plugs.

After having removed the lens with moter (without the circuit boardss attached) I used an external DC laboratory power supply set to 2V DC (and with current limitation activated) to directly power the lens motor at its two soldering points at the backside.
First it did not work at all, but maybe because of bad contacts.
But then I managed to let the lens move in and out by reversing polarity of the 2V.
After a few times the lens seemed to move much smoother.
With the lens still out I carefully re-assembled the camera again.
Now everything works fine again.

If you do not have a DC power supply you might be able to put the two batteries in series and apply that voltage to the motor.
Do not use a larger DC voltage than retrieved by those two batteries... or you might damage the motor or lens or...
I am not responsible if you damage your camera...

Be careful with the cables and note that a part of most of the small connectors can be carefully lifted upwards at the end to release the cables !

Maybe this helps to reactivate more of those stuck cameras.
Good luck !

Warning when i power on

The internals to the lens assembly is at fault and only a micro repair can fix it, sometimes it the pins that allows the lens to move are off track. sometimes its the focal motor within the lens. all are motor gear driven and stick randomly.
not worth fixin due to the falling prices.

Lens is not moving in or out

Two posibilities : lens impacted and has to be replaced complete ( the whole lens unit with both motors and CCD sensor ) this is expensive. Or is you are lucky the gearbox has a gear that has popped. Replacing gearbox is not so expensive.
