2-5-1. Notes on Spare Parts

(1) Safety Related Components Warning
Components marked ! are critical to safe operation.
Therefore, specified parts should be used in the case
of replacement.
(2) Standardization of Parts
Spare parts supplied from Sony Parts Center may not
be always identical with the parts which actually in use
due to "accommodating the improved parts and/or
engineering changes" or "standardization of genuine
parts". This manual's exploded views and electrical
spare parts list are indicating the part numbers of "the
standardized genuine parts at present".
(3) Stock of Parts
Parts marked with "o" SP (Supply Code) column of the
spare parts list are not normally required for routine
service work. Orders for parts marked with "o" will be
processed, but allow for additional delivery time.
(4) Units for Capacitors, Inductors and
Resistors
The following units are assumed in schematic
diagrams, electrical parts list and exploded views
unless otherwise specified.
Capacitors : µ F
Inductors : µ H
Resistors : Z

2-5-2. Replacement of Chip Parts

Replacement of Resistor and Capacitor
1. Place the soldering-iron tip onto the chip part and heat
it up until the solder is melted. When the solder is
melted, slide the chip part aside.
2. Make sure that there is no pattern peeling, damage and/
or bridge around the desoldering position.
3. After removing the chip part, presolder the area, in
which the new chip part is to be placed, with a thin
layer of solder.
4. Place new chip part in the desired position and solder
both ends.
NOTE Do not use a chip part again once it has been
removed.
Replacement of Transistors and Diodes
1. Cut the terminals of the chip part with nippers.
2. Remove the cut leads with soldering iron as above.
3. Make sure that there is no pattern peeling, damage and/
or bridge around the desoldering positions.
4. After removing the chip part, presolder the area, in
which the new chip part is to be placed, with a thin
layer of solder.
5. Place new chip part in the desired position and solder
the terminals.
Nipper
Transistor
Replacement of ICs
1. Using the braided wire, "SOLDER TAUL" (Sony Part
No. 7-641-300-81), remove the solder around the pins
of the IC-chip to be removed.
2. While heating up the pins, remove the pins one by one
using sharp-pointed tweezers.
3. Make sure that there is no pattern peeling, damage and/
or bridge around the desoldering position.
4. After removing the chip part, presolder the area, in
which the new chip part is to be placed, with a thin
layer of solder.
5. Place new chip part in the desired position and solder
the pins.
