This is how you fix it!
Step 1: You Will Need:
a little screwdriver: maybe one of the glasses screwdrivers from last years christmas cracker that you've never used?
some solder wire: needs to be suitable for electrical appliances (if it doesn't say it isn't, it probably is fine)
Make sure not to lose any of the parts (the front button and the two top button)
Your camera may flash when it has been done. Try pressing the 'on' button to see if the problem is solved.
