Try replacing the ribbon cable between power supply and digital board, I think it’s a 12 pin. Common problem if the speaker and fpb are not faulty
If that doesn’t sort it out maybe digital board?

Note, Wrench screen page two, upper left of screen you will see VD24 and VB24. Values should be ON. During test 16000, you should see these switching. Learn when they should switch and monitor. You may have a bad relay in your SMPS.

Pull SMPS out and ohm them. Surprise, the relays, 1F capacitors, sonic alarm and removable fuses (not soldered) are all repairable items on the SMPS. But <M> might be right, it may be the digital board.
