Olympus C-750 Ultra Zoot drives me crazy.

Discussion in 'Olympus' started by Robert Montgomery, Jun 28, 2008.

  1. I'm able to store customized settings of my Olympus C0750 Ultra Zoom and
    they last for one battery change. When I change my batteries for the
    second time, the customized settings are lost and they revert to the
    factory settings.

    Am I doing something wrong or is the camera malfunctioning?

    After I change the batteries twice consecutively, the camera resets to
    the factory settings the reset off, date, saturation, contrast, digital
    zoom setting, volume, power on sound, beep and a few other settings like
    that I've customized and saved in Mode Menu > Setup > My Mode Setup >
    My Mode 1 or My Mode 2 or My Mode 3 or My Mode 4 > OK.

    The customized setting are maintained for only changing of the batteries

    Most likely, a small internal backup battery is malfunctioning.
    If you're lucky, the camera will use a user replaceable button cell
    (check your camera's manual). If not, you may have to send the
    camera back to Olympus to be repaired. You may be able to avoid
    this if the camera has a socket for an external power supply, which
    if used while swapping batteries, might prevent the loss of your
    customized settings. Another thing that *might* work would be to
    connect the camera to your computer with a USB cable while changing
    batteries. If this results in a smoking puddle of molten plastic
    and metal, look on the bright side. This old 4mp camera was
    discontinued years ago, and you should be able to get a new camera
    that produces better pictures and has much better performance, for
    less than you paid for the C-750.

    You might even really like having a new super-zoom with a lens
    that goes wider than the 38mm of your C-750. Being able to go down
    to the 28mm of some of today's ultra zooms can be a big advantage at

  3. I seriously doubt any consumer camera has a user serviceable battery, they
    usually use some sort of capacitor, changing it is even more difficult.
    Connecting to USB is no good, camera is powered from battery anyway.

    Then you'd be wrong, as the manufacturers have explicitly stated
    in several manuals that "rechargeable batteries" are used for backup
    purposes. Of course (as you say) they're not user serviceable,
    which is why *most* people would need to have the cameras serviced
    by either the manufacturer or by skilled a camera repair service. I
    explicitly stated this, and you even quoted it. ("send the
    camera back to Olympus to be repaired").

    Second - I didn't say that using USB would definitely work
    ("Another thing that *might* work"), but that it might be worth
    trying. Some of my non-camera USB devices use only their own
    internal batteries, others use power from the USB port if available.
    I wouldn't expect the USB port to be able to provide sufficient
    power to actually take pictures, but there's a slim chance that it
    might allow the main battery to be safely exchanged. I'd first try
    it while the camera is powered OFF (assuming that being connected to
    an active USB port doesn't automatically turn on the camera). If
    that's not possible, or if it doesn't work, you could try to replace
    the battery while the camera is in file transfer/PTP mode, while in
    playback mode, or while in record mode, especially if the LCD is
    disabled and the shutter isn't accidentally depressed.

    That sometimes indicates smugness or not a true desire to help,
    especially when what was posted wasn't particularly helpful. I'll
    give you the benefit of the doubt, since unlike some of our resident
    "argumentators", your replies often do try to provide help. :)

    It's a well known problem with Olympus camera from that era, it's a memory
    backup capacitor that fails after a couple of years, mine's the same. An AC
    adapter plugged in while changing batteries gets round the problem, any
    universal one of the right voltage and polarity rated at more than 0.5A
    should be OK for this purpose. The capacitor can be changed if you're
    adventurous, here's a link to get you started.....

    Are you using the same batteries each time or do you have two sets, and
    if so, is the loss of setting linked to one specific set?

    How long does the camera remain without the batteries?

    If it's the usual C750 problem, it forgets everything you've set in the
    menus if good batteries are taken out even just for a couple of seconds.

    Yep, the memory's held up by a little 'super capacitor' which dies
    after a few years. Then the camera reverts to factory defaults the
    moment the batteries are disconnected. It happened to both my Olympus
    C-350 and C-740.
    Luckily those capacitors are fairly easy to get and I'm an
    electronics technician so I was able to successfully fix both cameras.
