3-13. NOTES ON REPAIR PARTS
3-13-1. Notes on Repair 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
Repair 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 : u F
Inductors : u H
Resistors : Z
3-13-2. Replacement Procedure for Chip Parts
Tools required
Soldering iron : 20 W
If possible, use a soldering-iron tip
heat-controller set to 270
±
10 d C.
Braided wire (Desodering metal braid) :
SOLDER TAUL or equivalent
Sony part No. 7-641-300-81
Solder : 0.6 mm dia. is recommended.
Sharp-pointed tweezers
Soldering conditions
Soldering iron temperature : 270
±
10 d C
Soldering time : two seconds per pin
. Resistor and Capacitor Replacement
(1) Place the soldering-iron tip onto the chip part and heat
it up until the solder melts.
When the solder melts, slide the chip part aside.
(2) Make sure that there is no pattern peeling, damage and/
or bridging around the desoldering position.
(3) After removing the chip part, presolder the area in
which the new chip is to be placed with a thin layer of
solder.
(4) Place new chip part in position and solder both ends.
Note :
Once a chip part has been removed never use
it again.
. Transistors and Diodes Replacement
(1) Cut the terminals of the chip part with nippers.
(2) Remove the cut leads as above.
(3) Make sure that there is no pattern peeling, damage and/
or bridging 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 position and solder the
terminals.
. IC Replacement
(1) Use the braided wire, remove the solder around the pins
of the IC-chip.
(2) While heating up the pins, remove them 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 placed with a thin layer of
solder.
(5) Place new chip part in the desired position and solder
the pins.
