He spent three hours tracing lines, drawing his own map on a notepad. The extra chip was a voltage supervisor. It was supposed to hold the PWM controller in reset until the 5V rail stabilized. But someone had bridged two pins with a tiny blob of solder—probably a factory rework. That bridge was causing the supervisor to latch incorrectly, cutting power after two seconds.
