About a week ago I cleaned my ATT CLF940 phone with a slightly wet rag. It stopped working for a bit, I turned it upside down for an hour, then all was well again. A day later the screen went blank, and stayed blank.
I can make and receive call with no problems.
The phone makes sounds when I push the buttons, but nothing ever appears on the screen, even when I call the phone.
I tried unplugging the phone for 1 minute, then plugging it back in.
Is there anything else I can try?
