• Cause: Input voltage exceeding 35V or shorted driver transistor.
• Schematic fix: Replace the 7812. Then measure resistance from the +28V rail to ground. If <100Ω, Q1 (driver) is shorted. Add a 0.1µF ceramic cap from input to ground directly at the 7812 pin 1.

"Sometimes," Elias said, folding the schematic back into its folder, "the best way forward is knowing exactly how we got here." Technical Context Wlx-896b Schematic
