We have a KR87 ADF where the display has gone blank. Or not quite — no numbers are visible on the display, but there is a glow around a few points at the bottom of the panel. Should I assume this is a display panel problem or could it be the driver circuitry?
If a part is working, it is probably not a cracked display panel.
I have the KR87MM, if you need it. I believe the driver chips are still available. I would just clean up the connections and change all the chips driving the display.

Got it, thanks. Very useful.
