Note for models with a power inlet having a built-in fuse
If the fuse built in the power inlet has blown, the power supply PCB could also be damaged.
Be sure to replace the whole power supply PCB ASSY, not just the fuse. Never use any
substitute or short-circuit the fuse terminals with conductors. Using a power inlet with an
unauthorized fuse will cause a fire or accident.
