Are those the AT102 scales? I have what appears to be the same scales on dad's lathe here, though we have an older generation box with all mechanical push-buttons.
When I had trouble with the long scale, it turned out to be the reader head had worn itself right through the aluminum diecast stalk because it had been knocked out of alignment. Because it was on the back of the machine I didn't know it was being damaged until the display just stopped while I was still cranking the carriage along.

The damage was limited to the reader head. The 800mm long scale was still fine. I found a 150mm scale on Ebay and bought it for about $50 (if I recall correctly.) I removed the head from the new one and installed it on the old 800mm scale. I still have the 150mm scale and housing if it's of any use to anyone. Hell, I'll even ship the busted reader head with it if anyone wants to try fixing it. It was still putting out a signal last time it had power to it!
