| Step | Action | Expected Result | |------|--------|------------------| | 1 | Listen with a non-conductive stethoscope or rolled paper tube to localize the crackling. | Identifies if from UPD board, ribbon cable, or logic power supply area. | | 2 | Check UPD connector J20 or J21 (varies by revision). Reseat the ribbon cable. | Crackling stops → loose connection. | | 3 | Measure logic supply voltages (typically 5V ±1%, 24V ±10%) at test points TP5, TP24. | Ripple >100mV or unstable voltage suggests failing caps. | | 4 | Perform infrared thermography (or careful finger touch – use gloves). | Hot spots (>80°C) on small blue/red capacitors indicate failure. |
