Note For Repair - Sony DSLR-A300 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-196 BOARD'S CHARGING CAPACITOR (C901)
The charging capacitor (C901) of the ST-196 board is charged
up to the maximum 330 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.

Note: High-voltage cautions
Discharging the Capacitor
Short-circuit between two points
with the short jig about 10 seconds.
