Discharging Of The Flashlight Power; Supply Capacitor; Preparing The Short Jig; Discharging The Capacitor - Sony DCR-PC110 Service Manual

4. DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR
The capacitor (C2010) of the flash unit is charged up to the maximum 300V potential.
There is a danger of electric shock by this high voltage when the capacitor is handled by hand. The electric shock is caused by the charged
voltage which is kept without discharging when the main power of the unit is simply turned off. Therefore, the remaining voltage must be
discharged as described below.
4-1.

PREPARING THE SHORT JIG

To preparing the short jig. a small clip is attached to each end of a resistor of 1kΩ/1W (1-215-869-11)
Wrap insulating tape fully around the reads of the resistor to prevent electric shock.

DISCHARGING THE CAPACITOR

* Use either one of the following two procedure to discharge the capacitor.
< DISCHARGING THE CAPACITOR-1 >
1 Remove the power supply (Battery or AC power adaptor).
2 Refer to "2. HOW TO OPEN THE FLASH WHEN THE FLASH DOESN'T OPEN" to open the flash. (Page 7)
3 Remove the upper ST cabinet.
4 Short circuit between the anode 3 of the xenon lamp and the GND # terminal of the trigger transformer (L2010) with the short jig
about 10 seconds.
