Troubleshooting Tips
BDC Camera Repair offers these suggestions to try first.

Before you send your camera to us, there are a few things you might want
to check.  Many times, your camera problems can be fixed by checking a
few things yourself.

  1. Are you using good, new batteries?  Lithium batteries cannot be
    accurately checked using conventional battery checkers --
    replacement is the surest way to check them.  If your camera uses AA
    or AAA batteries, be sure you have a fresh set of Alkaline batteries.
  2. Are the battery contacts clean?  Even a new battery cannot supply
    power to your camera if the contacts are not clean.  A cotton swab
    slightly moistened with rubbing alcohol can clean most contacts -- be
    sure not to get any alcohol on the camera's finish, or inside of it.
  3. Be sure all of the settings, buttons, switches, etc. are correct.  
    Sometimes the controls can get bumped or played with, and this can
    cause your camera to act in unexpected ways.
  4. Be sure that the film was loaded correctly.  Many cameras have a
    mark showing how far across you should pull the film when loading.  
    Pulling it too far across, or not far enough can cause the loading
    mechanism to work incorrectly.
  5. If your camera has a removable lens, is it mounted correctly?  If the
    lens and body are not correctly coupled, many problems can occur.
  6. Is the lens clean?  Many focus problems can be cured by ensuring
    that the lens is kept clean.  This includes any filters you may have
    installed, and the AF-sensor panel on the front of the camera, if so
    equipped.

If these suggestions don't help, it may well be time to send your camera in
for an estimate.
