I have a sony ericsson c510 model which is in the Cybershot series. i had only had it about 7 months and my friend one day was going through my pictures and i guess the phone got overwhelmed and the screen went black and the key lights turned off. well this had happened a couple of times before all i did was take the battery out and turn the phone back on and it would work but now when i turn the phone on all that shows up is the sony ericsson logo and then the screen will go black and it wont work..........does anyone know how to fix this or is the phone completely broken?
