Hi George:

A common problem with the 2100 series units is that the LCD gets loose 
in it's socket.
Unplug the two front panel ribbon cables, remove 6 screws.
Have a close look to see how the LCD is relative to the socket, then 
carefully remove and reinstall the LCD.
Let us know if that fixes it.


Have Fun,

Brooke Clarke, N6GCE
