ADI AT-600D---No Display?
 

Greetings:

I have an AT-600D ADI dual band HT in which the display has
gone blank. All functions still work, but you can't se what you're
doing, hi!!

I've disassembled the radio and checked the output of the
driver chip, and all lines seem to have the proper square wave
going to the display. I don't however see any data being pased
from the main chassis to the display board.

I'm working without a schematic here guys, so any leads to
where to look next would be appreciated. I can't see any damage
to the LCD panel itself, and have cleaned the two conductive
rubber strips joining the board to the display.

Thanks for any assistance.

Please reply to : or post here.
