Components identified by mark have special characteristics
important for safety.
Furthermore, special parts which have purposes of fire-retardant
(resistors), high-quality sound (capacitors), low-noise (resistors),
etc. are used.
When replacing any of components, be sure to use only
manufacturer’s specified parts shown in the parts list.
- The supply part number is described alone in the replacement parts
list.
- Voltage and signal line
: Positive voltage line
: Playback signal line
- The voltage values and waveforms are the reference voltage of this
measured by the DC electronic voltmeter (high impedance) and
oscilloscope on the basis of GND terminal (DC IN jack).
Accordingly, there may arise some errors in the voltage valuesand
waveforms depending upon the internal impedance of the tester or
measuring unit.
Measurement conditions:
- AC adaptor is used for power supply.
- Set the hold switch to ON.
- The parenthesized is the voltage for test disc (1 kHz, L+R, 0 dB) in
play mode, and the other, for no disc in stop mode.
Caution!
IC and LSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
Cover the parts boxes made of plastics with aluminum foil.
Ground the soldering iron.
Put a conductive mat on the work table.
Do not touch the legs of IC or LSI with the fingers directly.
