I have a wp810 that just shows a white screen when powered on, then will power off after a few moments. Any way to recover this?
WP810 Won't boot, white screen
Possible bad battery or charger not working. Try switching the battery out for another if you have one or try powering the phone up with it sitting in the charger.
Phone has a micro USB port for charging, try removing the battery, plug power on (directly in to the phone), waiting 60 seconds then try and power on, if it works then you have a battery / charge circuit issue in the phone.
