Problem
This troubleshooting article applies only to post 2020 machines
If the machine is not operating and the” information light” next to the power button and the firmware LED on the logic board flashes with the following eight-bit pattern as described here:
0011 0001
Where 0 indicates a short pulse which is 1/4 second and 1 indicates a long pulse which is 1 second long.
Since this is a high priority error, the internal piezo speaker will also output an accoustic signal with the same pattern.
This indicates that the Logic Board failed to configure the Amplifier Board for operation.
Solution
Check the following hardware:
Logic Board to Amplifier Board Cable
