-   Olympus C-770 will not shut off. On continued use, it will not go into the playback mode. We have left the battery out for a few days, but the time and date is still retained, so it must have an internal battery. Any suggestions?-   kramercd123

-   Also a C-770 owner, whose camera now will not shut off. We continue to use it, taking the battery out when we want it "off". However, now it will not enter the playback mode, either.-   Guest
This might be a serious problem requiring the power board (and maybe the main circuit board) to be replaced. What's the status of your warranty?
If valid, send it for repair. If expired get an estimate from olympus or a local shop that can handle it.
It was also common with the 990 when it came out. There were rumours then that it could be fixed by a firmware upgrade, you could try and see if there are any available from the Olympus site.
also try leaving it without batteries for 24 hrs. If there is an internal battery you'll need to either find it and remove it, or leave it without batteries for more than 48 hrs. but contacting olympus might be usefull because sometimes the internal battery can keep charge for more than a month. you can tell by checking to see if it keeps the date/time. if it does then it hasn't been reset.
This could also be a case of the lens been obstructed. Sometimes a camera can go flipping from that.

My Olympus C-770 camera will not record movies beyond a few seconds. It seems like anything over 30 or 45 seconds just gets corrupted. When I try to watch a corrupted movie on the camera, it displays "Picture Error" on a blue background with red text, and a red exclamation point in a red rectangle. They won't play on my computer either.

Initally camera would take 1-2 hours to shut-down (lens retract) and now progressed to camera will not turn on at all (with fully charged battery). Any suggestions? Not sure whether worth the $200+ repair costs from Olympus.
