Dear Forum,
I have two Displayotron HATS. I had one working at one time. Currently, neither of them are responsive after installing three different ways on either Raspberry Pi Zero W or Raspberry Pi 2. Each have been attempts with either Stretch or Jessie.
I have tried to install through Pimoroni Dashboard and the one-liner starting with curl -sS. On all these attempts, the Raspberry Pi operates normally with several different programs functioning successfully. Under all these attempts, the device has no output and screen is blank. I must be missing something.
The following is a session output to explain the problem:
Please help, Thank You, Frank.
