Hi,
I would suggest that you get the device serviced by the manufacturer.
There is, however, a way which has many reporting success.
You will need to solder the dew sensor to reset it and it might help you.
This process involves using the soldering iron and you should only attempt if you are handy with those. The incorrect use can render the camera in need of a big repair.
If you would like to try, please follow the
steps outlined on this page.
There are pictures to help you in identifying the parts too.
If this doesn't work for you, please comment and let me know, and I will be happy to assist you to further resolve your issue.
I will appreciate your feedback and positive rating for this solution.
Thank you.
