Is the phone on, even though the screen is black? OR is the phone completely off and appears to be 'dead' ?
Follow these instructions:
1) Power down phone & remove battery2) Insert battery w/o powering phone back on3) Simultaneously press the volume down button, green call button & red end button - hold all 3 down until SAMSUNG appears on screen and appears to be turning on4) A menu w/ options will appear, choose the bottom option (master reset device) - phone will erase all codes and programming (could take a minute, will show codes on screen being erased in yellow)5) When all is reset, will return to previous menu - choose 1st option to reboot the device6) Phone will reboot and power on
You don't HAVE to follow steps 4 and beyond. Were just trying to get the screen to work. If this doesn't work, then you've got a hardware problem on your hand. In that case you're limited to a warranty replacement if your device is less than 12 months old and free of physical damage. OR can be repaired by a third party repair vendor but you'll probably be spending around about $80 for that.
I hope this helps or at least points you in the right direction.
