Zoom in and zoom out button loose - Canon PowerShot G7 Digital Camera

normally there is a zoom button front of camera beside lens, it is like a toggle button press one side to zoom in, other side zoom out.
press the helpful button and follow me on fixya for more tips

Has this camera encountered any water or moisture? Sounds like the Ribbon cable to the
option panel is either loose or has been compromised. It could have come loose after a
drop or hit, compromised cables are results of water damage or moisture damage.

Howdy, this is usually controlled by the button marked ASPECT RATIO. pushing this several times will usually solve that issue.

The lens is damaged inside, no way to adjust that outside and it definately shouldn 't do it. You need to get it looked at.

I have had this same problem with mine, since the adapter jack is loose it's probably broken loose from the circuit board inside. I had to carefully dis-assemble and re-solder the adapter jack back to the circuit board. This is un-fortunately a weak point on some of Zoom's pedals, when you or if you get someone who is good at soldering to do it for you ask them to beef the solder joints up a little to help keep it from coming loose again. I re-did mine and I've never had another problem with it.

The zoom creep is an easy fix for Canon. I really do not recommend trying to tighten it yourself, since that would void your warranty.
It is usually free to tighten the zoom ring.

Remove your batteries and look inside the battery compartment. Notice that there should be three small phillips screws at the bottom of the compartment. Tighten up all of these screws.

I have the same problem. I hoped it was down to the zoom button on the top of the camera. I dismantled it and eventually got to the button but couldn't find anything loose/damaged or needing cleaned.

Did you ever find a solution?

the zoom control button is malfunctioning. try to clean the contact. check the resistant of the variable carbon. if it is not open, try to adjust the contact point away from the damaged area.

I don't know anything about this camera. However on most modern cameras, the Shutter Button is usually just part of a switch. Nearly always there is a rubber Diaphragm below the button, which has an electrically conducting lower surface. When the Button is pressed that surface touches a small printed circuit board, or part of a circuit board, and a number of circuits are closed. It could be that the lower surface has become stuck to the Circuit board, or the rubber diaphragm has moved and is jammed down. It might be possible for you to open the case, and get to this switch. Any other switches or buttons near by, will also become loose, so remember which goes back where. If you don't want to take any chances I would advice you to find a local repairer, who should be able to fix this fault very quickly and fairly cheaply. Good luck
