Schematic indicates the main 20V rail splits into +VBUS and +VAD. Using a thermal camera, +VAD shows a hot spot at PC101 (0.1µF, 25V cap). Remove it – short gone.
"Anything?" asked Clara, his apprentice, leaning over the workbench with a thermal probe in her hand.
High-value resistors (1–5 MΩ) in the startup path may go open-circuit.
