 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.
