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.
