Discharge the main high-voltage reservoir capacitor completely to avoid an electric shock. Inspect the top of the board for "domed" or leaking capacitors. Check the underside of the PCB for dark, scorched areas around the power transistors and diodes, which indicate localized overheating. Step 2: The Diode and Fuse Test
