I just bought (order TA15581) a wireless corne and everything seems to be working except one of the displays, which shows static.
The display was originally installed on the left. I swapped it with the working display from the right side and the left side continued to be the problem, so I think the display itself is fine.
I then swapped the nanos and the problem followed the left-side nano to the right-side.
I suspect it's bad in some way. I've tried the type active firmware and built my own as well. I also flashed both sides with reset firmware after swapping the nanos.
I also tried adding a keybind to set &ext_power EP_ON.
I'm using the no-solder headers, and I've taken a multimeter to the contacts and there seems to be continuity to all pins.
Anything else I could try?
