I have a "wireless display board" to use the second screen on, so I'm just building that up, and will see if that behaves any differently.

That's a good idea to test if the display is working, however even if it will work, the touch panel will be rotated. The software for the Nano based Wireless Display units wasn't adapted to also support those "yellow pins" displays.

Confession time:

I found in sorting things out that the "push button switch" I was using, and which has been in my junk box for 30+ years, is a "normally closed" one, not an NO as I thought.
That certainly hasn't helped.
I tried the latest software, and can now get it to connect to the wi-fi network, and set the RTC which is an advance.
Display is much the same, I notice it does "blink" when I press the NO button.

I have assembled the WD board, seems to be behaving much the same, with a white display, though it has a constant "flicker" as though it is refreshing.
The display seems to respond to touch, which the one on the Rx board doesn't.
Then when I tried to run it with the Rx board also running, I have (I think) a USB issue, and can't connect to monitor the serial output.
 
Pending the arrival of replacement displays, any ideas on debugging?
Assuming I can sort out the communication problem.
