Common failure modes for this class of supplies include overheating of the internal switching regulator, degradation of the output capacitors, or tripping of the built‑in overcurrent protection due to shorted load paths. First‑check steps: verify input voltage stability and polarity; measure the 5 V rail under no‑load and loaded conditions for dropout or ripple; inspect the board for burnt components, loose solder joints, or signs of thermal stress.
