Screen becomes blank

You will have to replace your screen. it is damaged.

This is a Software Failure Issue. The software is somehow corrupted. Try re-installing the software. Also another thing. The phone's firmware must have gone corrupt or it is Out-Dated. Contact the Motorola Customer Support and they will completely repair the Phone. In some cases, the repair is free.
Thank you, Have a nice day.

remove the memory card, then remove the battery from the phone. Wait a minute install battery into phone and turn on. If all is good, power phone off before installing memory card. As a safety precaution, do not install or remove memory cards, in any device, with power on.
