help blank screen on model 197

[RickTheRider]

I tried to program a new frequency and pushed the wrong button. I dont remember what I typed.The screen went blank. It still has a light when it is turned on and the audio still works but data ( numbers or letters) does not come up on the screen. I dont have a computer to program the scanner. How can I fix this? Thank you.

Are you doing TGRP or CONV ?

If you don't mind reprogramming everything, you can do a factory reset -

1. Turn it off
2. Turn it back on
3. When the welcome screen appears, press zero, then one, then enter. This will clear everything out and reset the scanner to factory settings. Then re-enter everything.

It's a brute-force method, but it works ...

I dont know what i was doing but I tried to take an old frequency out and tried to put in a new frequency number and the screen went blant . I think it was conventional.
