Camera turns on, then off immidietly I have a casio exilim ex-770 .. and the video play and menu work fine, but when I turn the camera on, it immediately turns off.

Sir,

Some cameras will automatically turn off if the camera is not used for about 90 seconds. This is a power save mode that is used to prevent the batteries from wearing down. Consult the instruction manual of your camera to determine if your model has this feature. If this is not the case and you've replaced the battery, then, service may be required.

thanks
good luck

How is the warranty on the camera? try to reset it to default settings. What you told us sounds like a hardware issue that would require repair. You can get a free repair estimate if you are outside of warranty from www.advancecamera.com/repair

Remove the battery, then press and hold on the power button for at least 10 seconds. Then replace the battery and turn on. This is a hardware reset that can be done on most electronics."
No joke, right after I did this, my camera not only turned on but also started charging when I put it back on the cradle! I hope this helps some of you who are having the same problem
