A face panel test can help identify if a problem is hardware or software. The face panel test is external to the Eos family software and can be found in the shell.
Fix/Solution
Exit back to the shell by pressing [Displays] and double-clicking with the mouse on {Exit}
Once in the shell click on {settings} and make sure you're on the maintenance tab
In maintenance, click on "Face panel test" on some consoles it could be called {peripheral test}
The peripheral test will show a tab for every bit of Eos family hardware connected to your console. For the Eos family face panel, you can see a graphical representation of all the buttons, encoders and level wheel. Moving or pressing will indicate if a control signal is received.
