Note For Repair; Preparing The Short Jig - Sony DSC-T70 Service Manual

NOTE FOR REPAIR

• Make sure that the flat cable and flexible board are not cracked of bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
• When remove a connector, don't pull at wire of connector. It is possible that a wire is snapped.
• When installing a connector, don't press down at wire of connector.
It is possible that a wire is snapped.
• Do not apply excessive load to the gilded flexible board.
DISCHARGING OF THE ST-172 BOARD'S CHARGING CAPACITORS (C901, C902)
The charging capacitors (C901, C902) of the ST-172 board is
charged up to the maximum 315 V 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.

Preparing the Short Jig

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

Wrap insulating tape.
Note: High-voltage cautions
Discharging the Capacitor
Short-circuit between the two points with the
short jig about 10 seconds.
To avoid the spark with the metal plate,
wrap the short jig with the insulation tape.
