Discharging Storage Capacitors; Checking Fr-181 Board - Sony DSC-S75 Training Manual

Discharging Storage Capacitors

CAUTION: Do not handle the BT-006 board without first discharging the flash storage capacitors. Make a discharge
jig from a 1K ohm - 1W resistor (Sony pn: 1-215-869-11) and two hook clip leads.

Checking FR-181 Board

•
The output voltages from the FR-181
board can be checked live at
connectors CN301 and CN308. Set
up the camera as shown in the picture
so that the board can be checked live.
•
If there are no output voltages, check
if the SCP line with an oscilloscope to
see if the line goes LOW. If it does,
then the problem may be caused by a
short or overload in the lens assembly,
the SY-072 board or PD-155 board.
Disconnect them one at a time.
