[CA] [CA11] Autohelm ST6000+ Display problem

[wotdoino]

When activating my Autopilot, my display unit has all the LCD elements displaying as 'on' (see attached picture). That said, it intermittently displays OK for the odd second or two, especially if I waggle the Seatalk connector from behind. Do you think there is a connection problem in the unit itself?

I'm the new owner of this boat and I haven't trialed the Autopilot so I don't know if it works properly yet (the previous owner said it did), that said, when I switch the unit to 'Auto' and press one of the -ve or +ve buttons, the helm is turned so that's a good start. Obviously I need a working control display to use it properly.

Any help is gratefully received!
