Question about Olympus Camedia C-725 Digital Camera

1 Answer

Sticky Zoom Control

Once my camera warms up, the zoom control becomes sticky. After moving this control to the right or left, it should immediately move back to the centre position once released. It moves back too slowly resulting in the lens continuing to move in or out. In addition, the shutter button (part of the same control) sometimes sticks. I assume that something was spilled into the control at some time. I've removed the screws releasing the control but there is nothing obviously wrong to the naked eye. Before I take it in for a potentially costly repair, is there anything I can spray in the mechanism that may clear the problem but not harm the circuitry? Thanks in advance. Clark Martin

    I was able to find a solution to my problem on newsgroup 'rec.photo.digital'. I'm posting it here for any who may have a similar problem.

    Shut off camera and remove batteries.
    Remove the two screws holding the zoom/shutter control in place. Remove the control being careful not to pull on the small ribbon cable. Cover the camera cavity to prevent anything from falling inside. Lightly spray the top and bottom of the control with Isopropyl Alcohol. (I used a 99% pure solution). Now squeeze a length of Dental Floss (I used the waxed stuff) under the zoom control - top-side of the control. Loop it around under the control and move it back and forth a few times. Remove the floss. In my case, there was visible black grunge on the floss, no doubt the sticky substance causing the problem. Spray in more alcohol. Using a can of compressed air, dry the entire control as much as possible. The air pressure may force out more contamination. Let it sit for several hours to assure it's thoroughly dry. Reassemble. Voila! Problem solved.

this camcorder is an earlier model thus the zoom control motor could be weak, if so open it and take out the camera section and unscrew the zoom control motor, loosen it, some sort of sticky grease on the worm gear also obstructs, clean it with small brush or cotton bud. then apply a little silicon grease. don't let dust go in.

Take your camera to a Canon authorized service center and see if they can try to clean the button area. This might solve your issue. Other than a cleaning they will most likely have to replace the button assembly and/or top cover depending on how the camera is designed.

Turn on the unit and goes to full zoom. Back it off manually, it will immediately return to full zoom. Unit was bought new about 6 years ago.

My camera did the same....it turned out to be a sticking zoom switch. With the camera turned OFF... move the zoom button ON TOP ( above the view finder) of the camera to the left and right about 20 or 30 times... then turn the camera on and try it.... very simple... but it worked for me :o)
