]
(1) Unplug the power cord.
(2) Remove the Cabinet.
(Refer to the
“

Cabinet”
. )
(3) Connect J304(-30V) of the MAIN ASSY to
J272(GND), with a resistor of 47 to 100
Ω
,
2W or more.
∗
Discharge time: 5 to 10 sec. (according to
the resistor.)
(4) Check by a tester if the voltage of -30V
terminal is 1 V or less.
∗
Connect the tester's GND terminal to a
Chassis.
∗
If the voltage is higher than 1V, repeat the
step (3).
