Introduction
not start or react at all when pressing the power button. Disconnecting the power cord, waiting for some seconds and reconnecting resulted in the startup of the printer, but it would immediately shut down with the message that all "All functions will be disabled". In the comments of a Youtube video I found a workaround (https://www.youtube.com/watch?v=Gi7cl588J8Q) namely to remove the paper tray before reconnecting the power cord and reinserting it not until the printer asks for it. That workaround did work for, but that was not a permanent nor a convenient solution. [ … ] Since the warranty of the printer was not expired, Brother sent me a technician who replaced a capacitor. After two or three restarts of the printer, on which the printer still misbehaved, the printer started working normally again. [ … ] at least a little experienced in disassembling and reassembling things.

Summary
not react start on pressing the power button, even disconnecting and reconnecting the power results in an immediate shutdown of the device. Replacing one capacitor on the motherboard solves the problem.
