IMPORTANT SERVICE NOTES (FOR QT-CD131 ONLY)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment
covers or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

hazard which must be corrected before returning the audio
product to the owner.

CD SECTION
Since this CD system incorporates the following automatic
adjustment function, when the pickup is replaced, it is necessary
to reajust it.
Since this CD unit does not need adjustment, the combination
of PWB and laser pickup unit is not restricted.
TEST MODE
Start
Note
Operation
While holding down the "STOP" button, move the FUNCTION/POWER switch to "CD".
Then, release the "STOP" button and, within 0.5 second, connect the TEST POINT to GND (within 0.5 second).
(See Fig. 7)
1. When the CD LID switch is in the OFF position, the unit will be able to enter the test mode.
However, playback cannot be performed in this mode.
2. You can only move the pickup.
3. The LCD display should be the same as it is for normal CD operations.
1
The use of the "UP/CUE" button will move the pickup to the outermost position.
The use of the "DOWN/REVIEW" button will move the pickup to the innermost position.
2
When the "PLAY" button is pressed, the laser will be lit, and when the "STOP" button is pressed, it will be
turned off. Playback will also start and stop when these buttons are pressed.
a. If the "PLAY" button is pressed while in the stop mode, the laser will simply be turned on at first.
b. If the laser is lit and the "PLAY" button is pressed again, playback will start from the current pickup position.
c. If the "STOP" button is pressed, playback will stop. When pressed again, the laser will be turned off.
3
Turning the tracking servo on or off.
a. Each time the PAUSE button is pressed during playback, the tracking servo will be turned on or off.
(Note: If the PLAY button is pressed while in the stop mode, the tracking servo will automatically be
turned on.)

NOTES ON SCHEMATIC DIAGRAM
• Resistor:
To differentiate the units of resistors, the symbol as K and M
are used: the symbol K means 1000 ohm and the symbol M
means 1000 kohm and the resistor without any symbol is an
ohm resistor. The resistor designated "Fusible" is a fuse type
resistor
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the capacitor
without such a symbol is microfarad. As to electrolytic capacitor,
the expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
• The indicated voltage in each section is the one measured by
Digital Multimeter between such a section and the chassis
with no signal given.

TROUBLESHOOTING (CD SECTION)
When the CD does not function
When the CD section does not operate When the objective lens of the optical pickup is dirty,this section may not operate.Clean
the objective lens,and check the playback operation.When this section does not operate even after the above step is taken,check
the following items.
Remove the cabinet and follow the troubleshooting instructions.
"Track skipping and/or no TOC(Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens.
Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."
Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.
• The CD function will not work.
The CD operating keys don't work.
Yes
Check the CD, DPS microcomputer (IC701), power supply, 4.19
MHz and 16.93 MHz clock, and reset terminal.
Yes
Check the waveform of SCK, SO (DATA) and SI (COMM).
Yes
See if the pick-up is in the pick-up in SW702 position.
Yes
If the items mentioned above are OK, check the main
microcomputer IC701.
• The CD operating keys work.
Check the Focus - HF system.
Playback can be performed without a disc.
Yes
Does the pick-up move up and down twice?
Focus search OK.
Yes
No
Does the output waveform of IC801(16)(FD) match that shown in
Fig. 22?
Check the area around IC804-BI801/CNS801.
Yes
No
Check the IC801(50)(CLK) line, 4MHz.
Check the microcomputer data on pins (51)(CL), (52)(DAT) and

Input
LCD power input terminals. To use the internal resistor, connect VLC3 to VDD (if a brightness
control is needed, connect VLC3 to VDD through a resistor). When an external power supply is
used, applyvoltages as follows: 0<VLC1<VLC3<VLCD<VDD.

Input/Output Reset pulse input/output terminal. When a reset is caused by the watch dog timer, an "L" level will
be output. The output is an N channel open drain.
Input
Input/output terminals for the main clock generation circuit. Used by connecting a ceramic resonator
between the XIN and XOUT terminals. There is a built-in feedback resistor between the XIN and
XOUT terminals.

XOUT terminals.
GND input terminal.
Positive power supply terminal.
Output
Input/output terminals for the sub clock generation circuit. Used by connecting a crystal oscillator
between the XCIN and XCOUT terminals. There is a built-in feedback resistor between the XCIN
and XCOUT terminals.
Input
Input/output terminals for the sub clock generation circuit. Used by connecting a crystal oscillator
between the XCIN and XCOUT terminals. There is a built-in feedback resistor between the XCIN
and XCOUT terminals.
Input/Output Used to input or output 4 bits at a time. When the output latch is set to "1", the unit will be in the
input mode. The key-on wakeup function, which can be switched on or off by the software, and a
pull-up transistor, which can be turned on or off by the software, are built in.
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.

If there are no indications for the electrolytic capacitors, error is ±20%.
If there are no indications for other parts, the resistors are ±5%
carbon-film type.
NOTE:
Parts marked with “
