Blank control panel

I have been working on this dishwasher for weeks with intermittent success. At first I had a blinking “rinse only” key, indicating a “stuck key without a light”.

  1. I replaced the door latch micro-switch. The dishwasher ran a couple of cycles normally, and repeated the symptoms.

  2. I replaced the control panel. The dishwasher ran through one and a half cycles, and stopped. No lights or LEDs at all, no functionality.

  3. I replaced the electronic control unit. Still no lights or LEDs at all.

I have confirmed power to the unit. Is the control panel a bad part? Is there a circuit breaker inside the unit? Help?!
