Discharging Of The Flashlight Power; Supply Capacitor; Preparing The Short Jig; Discharging The Capacitor - Sony DCR-TRV30E Service Manual

3. DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR
The power supply capacitor 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.
3-1.

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.
3-2.

DISCHARGING THE CAPACITOR

1 Remove the power supply (Battery or AC power adaptor).
2 Open the cassette lid (grip cabinet).
3 Remove the two screws with which the grip cover is fixed.
4 Remove the grip cover.
5 Remove the insulation sheet.
6 Short circuit between 3 and # terminal of the capacitor with the short jig about 10 seconds.
Note for installing the grip cover
When installing the grip cover, insert it in the claws of the grip cabinet.
