Discharging Of The Flashlight Power; Supply Capacitor; Preparing The Short Jig; Discharging The Capacitor - Sony DCR-HC1000 Service Manual

4. DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR
The power supply capacitor (ST-106 board C5605) 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

1 Remove the cabinet (L) assembly and the grip assembly.
2 Remove the MS-220 board.
3 Remove the VC-366 board.
4 Remove the JK-271 board.
5 Remove the DB-017 board.
6 Remove the center frame.
7 Remove the lens assembly.
8 Remove the Battery holder and the EVF block.
9 Short-circuit between LN5604(+) and LN5603(-) of the ST-106 board with short jig about 10 seconds.
