NOTE
To discharge the high voltage capacitor, wait for 60
seconds and then short-circuit the connection of the
high-voltage capacitor (that is the connecting lead of
the high-voltage rectifier) against the chassis with the
use of an insulated screwdriver.

according to the following procedure.
7. Hold the edge of the rotor of the fan motor by using
a pair of groove joint pliers.
CAUTION
Make sure that any pieces do not enter the gap
between the rotor and the stator of the fan
motor, as the rotor is easy to be shaven by pliers
and metal pieces may be produced.
Do not touch the pliers to the coil of the fan
motor because the coil may be cut or damaged.
Do not disfigure the bracket by touching with
the pliers.
8. Remove the fan blade from the shaft of the fan
motor by pulling and rotating the fan blade with your
