Question about Sony Cyber-Shot DSC-P73 Digital Camera

Broken zoom gear

My camera was dropped on the lens while it was extended and it got pushed back in, breaking some teeth off the small gear that extends the lens. I know this is the problem because i took the camera apart and pulled the broken gear off. I was wondering if any one knew where i could get a replacemt gear? Thanks joe

    Here is a picture of where the gear is located, it might give you a better idea of what the gear looks like.

Getting an zoom error on my fuji film finepix z90, what can i do?

Lens errors (zoom errors on Fuji's) are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ... Unfortunately, many cameras that fall prey to lens error problems can only be corrected by professional repair. But, here are some last resort troubleshooting steps that you can try that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try.

The 18-70mm lens on my Nikon D70 is stuck on zoom. I can't take it back in to take a wider shot. I haven't dropped it or damaged it in any way. Any suggestions?

take the lens off the camera, try to change the zoom on the lens. if it works then your lens is ok. on the front lens mount surface of your d70 there is a small "driver" connection, it is in the lower left of the metal surface . this connects to the socket on the lens when the lens is mounted. by the way, your lens doesn't have this though. if your lens moves then your camera body is the problem. your lens is electrically operated for focus only, it is manually zoomed. if you can't zoom it by hand when removed than your lens is probably broken, many of the parts inside these lenses are quite delicate and won't take much of a bump on the front end to break the inside parts, i know, i have broken a few..hope this helps.

The zoom ring has limited use...maybe something stuck inside lens

If you are unable to maximize the zoom capabalities of your lens, the mechanical gears might have been jammed and or broken. Do not push it if it won't let you as you might break the lense. What you can do is to bring it to your local camera shop or service center to have it fixed.

'zoom error' on olympus sp-560 uz

I had this problem and managed to fix it. The camera was dropped on a stone floor and the zoom error was present every time it was turned on. A ring or other piece of the lens was bent or damaged, in my non professional opinion. A profesional repair is my advice. However you may try my fix at YOUR OWN RISK.

Switch camera on, when zoom extends, but before it closes down due to zoom error, gently but firmly push lens back in. Drop batteries for camera to reset itself. Repeat, if necessary.

My camera now operates fully and when the lens extends it now no longer makes the slight grinding noise.

Good luck and remember at your own risk.

I had the same problem with mine after I dropped my camera when it was opening up after turning on. It feel directly on the lens and ever sense has told be to remove the lens cap.

I’ve disassembled the camera and discovered that the zoom motor drive assembly has a small set of plastic gears inside that are quite fragile and like mine are easily broken. You’ll find the zoom motor after taking the back assembly of the camera off. It’s located on the bottom left side of the lens assembly if you're looking at the camera as if you were taking a shot.

Here’s the part no. from the Panasonic support web site.....


Olympus 8080 C 8080 wide zoom

It may have jumped a tooth, something like a car timing chain. The Zoom in this camera is a barrel that has 3 cams that rides inside another barrel that has "tracks" for the cams. The motor rotates the the outer barrel via gear teeth, forcing the inner barrel to extend or retract. There is a tab on the gear teeth that might index the position of the zoom lens. If this tab is in the wrong position, if the gear jumped a few teeth, the camera may not know where the zoom lens is in relation to the inner focusing lens, and cause the "zoom error" If that is the case, I can help you get it back into position. This is a theory, but does explain the tab on the gear and the constant zooming.

Kodak V803 Digital Zoom Camera turns off when I try to zoom.

The problem will more then likely be either a worn/broken gear or the gears have accumulated a bit of dust in them.
If you send it back they should be able to do the reapir easlily enough, but price wise you will be at their mercy.

If you decide to send it back try this first..(pending the lens stays out after it shuts off)
Turn the camera on. Activate the zoom function. Grab the lens and GENTLY pull it outwards in a straight line. Do not pull it on any sort of angle. If you use force, then it will damage the gears.
This will only help if a small amount of dirt is stuck between the gears.

If the lens goes back in when it shuts down then..
face the camera towards you. As the lens moves out grip it and do as above. But at all times, do it GENTLY.

As I said, this will only help if a small amount of dirt is wedged between the teeth in the gears. If you need to apply force, then it is more serious and this will not help.

If the camera is under 12 months old then the warranty should still be good, and sending it back is the better option. However, if they find dirt in the gears, they may decide to charge you since in their eyes it is not a malfunction. They will accept it for repairs at any time, it's just when out of warranty, or through damage not covered by the warranty you will be charged.

Putting Lens Back on

How far apart are you? I mean it all goes back together in reverse order. If the lens is disassembled, you need to get the outer lens tube back on its tracks in the inner tube. That takes a little working, but it should be doable. You should be able to turn the small gear that is on the lens assembly and be able to extend the zoom lens, itll be tough, but if you cant, then the camera will probably not be able to do it either, look for something off track.

Sony Cybershot 7.2

I did the exact same thing and my lens was at an angle too. The camera kept telling me to power off and back on. I removed the exterior panels with a precision screwdriver and just applied pressure to the extended lens with my fingers. It turned out I could have done the same thing without taking anything apart. It took quite a bit of pressure before the lens snapped back into place. I believe it's possible to break the lens this way, so just be advised.....but given a choice between trying that and throwing the camera away, I'd go ahead and try it. It worked for me. Best of luck to you!
