Service Note; Note For Repair; Discharging Of The St-105 Flexible Board's Charging; Capacitor (C550) - Sony Cyber-shot DSC-P150 Service Manual

1-1. 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.
Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)
1-2. DISCHARGING OF THE ST-105
FLEXIBLE BOARD'S CHARGING

CAPACITOR (C550)

The charging capacitor (C550) of the ST-105 flexible board is
charged up to the maximum 300 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.

SERVICE NOTE

1 kΩ/1 W
Wrap insulating tape.
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.
Discharging the Capacitor
Short-circuit between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.
