Roland CR-8000 cannot erase programs...

I have a CR-8000 that, for the most part, works well outside of the programmer. All of the buttons work, tempo seems solid, trigger output is fine, etc. But the programmer has never worked. So I've reduced to playing it with the preset patterns, which is getting kind of old and not really unlocking the potential.

I've changed out the batteries, which I'm not sure even has an effect while the unit is powered on, but basically the buttons all 'respond' in the way they should, ie: when you hold down register and crash, the programmed location should blink indicating it's been erased. So this happens, as you can see in the video I'm posting below, but the patterns are still there. And each location has the same stagnant pattern and doesn't really restart or change when you select different program buttons/locations.

I looked a bit in the service manual but I haven't grasped the circuit just yet. I'm curious if any CR-8000 owners ever had a problem with theirs and know some common or typical failures.

I've had it for a few years now and it's in great shape, but I've never done any work on it.
