Did you try the "REV" buttons?

Have you just replaced the EPROM? I read somewhere that someone did this and they had to put to slew mode back to visual via RS232 for the system to restore...don't know why.

Is your cable to the HC ok?

You mentioned RS232. Gemini1's are particular about what or how much +5V is drawn from the system (PCB) and plugging in/out RS232, Auto-guider ports can shut-down the HC. Maybe remove them (all other devices) and try a re-boot. My Gemini BT was originally designed to use Gemini +5V but I found that sometimes plugging it in/out would cause the hand controller to go blank....aka a +5V line shut down.
G'day Brendan,
The HC functions normally in all other respects. The LED is operational,

All the boot process is normal, display normal, menu operation normal.

And the problem is present whether the RS232 is connected or not.

Haven't tried the REV button yet. Will give that a whirl. HC Cable looks fine.

I'm in the process of doing a full rebuild on that mount today and will be renewing all lings and connections. I'll report again after that.

Peter
