This is where we discuss how to repair appliances, large and small. We are not waiting for #right2repair law to be enacted. The civil disobedient practice of repairing instead of wasting and re-buying is welcome here. I will also turn a blind eye toward “piracy” of manufacturer service manuals that are otherwise unavailable to the general public.
You might see if you can find a service manual for the specific make and model, it could be as simple as a hidden breaker switch that flips to factory defaults.
Of course not all makes and models are out there, but a lot are!

There is no service manual within my reach. I would have to resort to bribery, torture, breaking and entry, and theft to get one. Thanks for the link but that only seems to cover N.American makes.
This is in fact why I am looking to probe the serial port. To try to poke around since I don’t know the secret steps to reseting the board.
