My Sony Ericsson c510 froze earlier when I was trying to access the address book, I took the battery out and put it back in and when I turned it on it displayed the Sony Ericsson screen (after a longer than usual wait) then after displaying it for a few minutes it goes to a blank black screen, the phone is still on but does not move on from this screen. I have tried fully charging it to see if that would help, taken the battery out a number of times and removed any dust, I've also taken the simcard out and turned it on to see if there would be any change. Nothing I have tried has made any difference.
Any advice?
