Display shows "Contact Service"

Troubleshooting flow
This error can only happen at power up where several self-tests are run. If any of these test cases fails the
display will show the message: "Contact Service".
They are individual test cases, so the below lineup of error hunting's has no chronological order. Use common
sense and experience to decide which test case to start error hunting at.
