Could a failing Power Control Module cause the BOSCH SHP865ZD5N to have symptom: Dead No Lights?

The Power Control Module houses the AC-to-DC conversion circuitry. In a 'no lights' condition, the most common failure is the breakdown of the switched-mode power supply components, such as the voltage regulator or capacitors on the primary side. If this board fails to output DC voltage, the logic controls and user display will remain unpowered regardless of incoming AC supply.

Could a failing Dishwasher Power Cord with Junction Box cause the BOSCH SHP865ZD5N to have symptom: Dead No Lights?

Bosch utilizes a specific external junction box that connects to the dishwasher via a proprietary plug. Mechanical stress or poor terminal contact within this box can lead to high-resistance carbonization, eventually resulting in an open circuit. This eliminates all power to the appliance, mimicking a dead control board.

Could a failing User Interface (UI) Control Module cause the BOSCH SHP865ZD5N to have symptom: Dead No Lights?

The UI module contains the micro-LEDs and tactile switches. While less likely to cause a 'completely dead' state than the PCM, a shorted capacitor on the UI's local rail can pull down the entire communication bus, preventing the unit from initiating its startup sequence or illuminating any display elements.
