Since my last posting on this subject, I have an update.
During the Winter I was having the same issue, touch screen not responding, so I started unplugging the hand controller (HC) from the Gemini II and taking it inside house. When I plugged the HC back in and the touch screen responded. Now during the warmer months that touch response no longer worked so I reset the chip inside the HC and reseated the touch screen. Problem still existed because I continued to unplug the HC and taking it inside.?
?
One night the touch screen responded and I forgot to dethatch the HC and the next night again I had luck with the touch screen responding once again. So for the last two weeks I have left the HC plugged in and everything is 'fat and happy' with the touch screen responding.?
?
Fingers are crossed for my continued success with the touch screen responding.
