Service Information S170
You may have a complaint about the S170 initialising. This may
be due to the power supply connector pins making poor contact.
To improve contact between the power supply and the pc board
perform the following .From the connector marked X27 ,the wires will have
to be soldered directly to the pins on the pc board . This is a 6 pin connector
with only 5 wires used. Unplug the connector from the board and cut the wires
from the connector. Strip and solder each power supply wire to its
corresponding pin labelled on the pc board. See diagram 1. Use heat shrink
tubing to prevent shorting the wires when soldering to the pins on the pc
board . I f the unit is received for general service this procedure should be
carried out.
