This may be too late to help but I promise it is perfectly true. I had the same problem with mine after a few years of trouble free use. After reading the comments here I decided to investigate or throw it away and get a replacement. Being a little mechanical I decided that nothing would be lost by trying to determine the fault. The very small screws in the case proved very hard to remove and as so very often happens there is always ONE! after numerous attempts I resorted to taps with a small hammer on the top of the small screwdriver to try and create a little more groove and get the screw to move. After starting to get a little aggressive and still no movement I decided to give up as I reasoned HAMMERING WOULD NOT SOLVE ANYTHING OR WOUD IT ? So in a last despairing gesture I switched back on and LOW & BEHOLD the camera now works fine again !! Can’t guarantee this method but I promise it worked for me and scored Brownee points from my wife who bought it me as a birthday present
