V5 synscan hand controller issue

I was setting up for a clear night today and came across this issue with my hand controller. This is the first time it’s done this. All my setup is exactly the same with power coming from mains. I’ve read something about low voltage or current, but it worked perfectly before with the same cable! I tried connecting it to my other mount with another cable and the same issue occurred. This has led me to believe my hand controller has been damaged in some way? Has anyone experienced this before?

I’ve been working on the Pacman nebula over the past few days but I thought I’d make a start on the California the other night. I’m Just amazed the difference this mono camera is having for my narrowband images.

Look forward to adding some more subs and potentially OII and SII
