Hi callemoss,
I am not sure, if I understood your problem correctly...
When you turn the camera on and "clock set mode" appears, are you able to set date and time? If the camera is froozen and you cannot set date and time, it looks like a defect.
In case you can set date and time and after that you are able to take pictures again, try the following:
Recharge the battery complete, put it into the W55, turn it on, set date and time, turn it off again and wait 12-24 hours.
The reason for that is the following:
Usually cameras have a small, second battery inside that remembers date and time when the normal battery is empty or placed outside the camera for a longer time. This internal battery is automatically recharged by the normal battery, but when the camera is old or was not used for a long time the internal battery might be defective or just very, very empty.
When turning the camera back on after having a fully recharged inserted for a longer time, the internal battery may have recharged and normal operation will be possible again.
Good luck!
