We have a 7921G phone that overnight has come up with an all white LED screen. The phone is still functioning, calls come in and can be made, but nothing shows up on the screen. Anyone have any ideas as to what the issue may be? I've reset the battery and powered the phone off and on several times. The phone was on the charger all night, and when we arrived this morning the LED is blank, just a white screen.
