How to Discharge the Capacitor on Jack PCB
When removal the jack P.C.B., it is protected with a capacitor cover. So do not have to discharge the capacitor.
However, when replacement it, remove the capacitor cover with unscrew 2 points, and then discharge the capacitor as follows.
CAUTION:
1.
Be sure to discharge the capacitor on JACK PCB.
2.
Be careful of the high voltage circuit on JACK PCB when servicing.
[Discharging Procedure]
1. Refer to the disassemble procedure and Remove the necessary parts/unit.
2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k
Ω
/5W).
(an equivalent type of resistor may be used.)
3. Put the resistor between both terminals of capacitor on JACK PCB for approx. 5 seconds.
4. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.
