Don't know if your problem was the same as mine, but when I went to take a photo in the beginning of the year, all I got on my camera was a dark screen with the icons showing. It was suggested that giving the camera a gentle tap on the side would clear the dark screen, which it did for a while, then kaput, no more screen.
Found out later that the model of my camera was no longer in stock due to many complaints of the above.
It was cheaper for me to buy a new one than get it fixed.
Sorry I can't be of further help.
Cheers
