IMPORTANT SERVICE NOTES
BEFORE RETURNING THE AUDIO PRODUCT
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 1.5 kohm, 10 watt resistor paralleled
by a 0.15 µF capacitor in series with all exposed metal cabinet parts
and a known earth ground, such as conduit or electrical ground con-
nected 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.
All check must be repeated with the AC line cord plug connection
reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.) or
more is excessive and indicates a potential shock hazard which must
be corrected before returning the audio product to the owner.

PRECAUTIONS FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"All PWBs" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The
alphabetical character following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage
or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C, we recommend you to use a dedicated soldering bit,
if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by 40 °C, and as it has poor
solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be
peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady
soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn on and off the power of the bit as
required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

CHAPTER 2. ADJUSTMENTS
[1] 1-bit section
1. 1-bit amplifier’s output offset voltage adjustment
Adjustment VRA100, VRA101, VRA200, VRA201, VRA300 and
VRA301 so that the DC voltage between speaker terminals (SO801) +
and - is set to 0 ±5 mV at AC 120 V.
[2] DVD/CD section
Since this DVD/CD system incorporates the following automatic adjust-
ment functions, readjustment is not needed when replacing the pickup.
Therefore, different PWBs and pickups can be combined freely.
Each time a disc is changed, these adjustments are preformed auto-
matically. Therefore, playback of each disc can be preformed under
optimum conditions.

NOTE: On conventional Sharp audio products, the memory is all ini-
tialized when the microprocessor starts up after entering a test
mode (incorrect memory check bit values are written and then
all memory is initialized by the initializing process). From this
model, the memory is not initialized unless necessary and is
all initialized only when the factory test is performed. However,
the memory is all initialized after exiting some test modes.
Refer to the specification of each test mode for details.
1.3. ALL CLEAR MODE for users (Operation Manual)
Method to enter
1) While in POWER_OFF mode.
2) While hold the [STOP] and [DISC5] button, press [POWER] button.
3) Send to AMP the “ALL CLEAR” code.
4) Go to Power On process and then display “ALL CLEAR” for 1 sec.
5) DVD-SYSTEM and AMP MICON RAM are cleared the all.
6) After that go to power off automatically.
2. Factory TEST Mode
2.1. Outline
All settings in the memory (including those preset) return to their
defaults.
2.2. TEST Mode Operation
When entering the factory test mode,
1. Data in the backup memory is all cleared and the power turns on
(this is the early stage of the system startup).
Key code for this test is sent to AMP.
2. Preset stations in the tuner preset memory on the EEPROM are
cleared.
When the DVD function is activated and the DVD Wake-Up data
(0x86) is received from ESS, the [Factory Reset] command (0x7A)
is sent to ESS.
Then the program version is sent to the system, which appears on
the LCD for at least 2 seconds (remains until the changer is initial-
ized).
3. The changer is set to the initial position.
The drum is stored into the unit (home position).
The mode cam gear moves to the No. 3 position.
4. After all the above processes are correctly completed, “COM-
PLETE” appears with all the buttons disabled (power can be turned
off).
5. When all the above processes cannot be completed correctly:
1) When communication cannot be established in the DVD func-
tion setup and the process results in an error, or when
DISC_ERR is sent back.
2) When the changer cannot be initialized and a corresponding
error is detected.
In either situation, “ERROR” appears for 3 seconds with all the but-
tons disabled (power can be turned off).
2.3. Supplementary Note
1. During the process, all the buttons are disabled.
2. Send the [Factory Reset] command to ESS. The display similar to
“VER:4.1.31.1 S-USA00x” appears on the TV screen. The last 3
digits 00x indicate the firmware version. For example, 001 = Ver
0.01, 101 = Ver 1.01.
Data - “title (41)”, “chapter (31)”, “minute (00)” and “second (0x)”-
will be sent to the system microprocessor side.
3. Refer to minute data (0 x 21) and second data (0 x 22) from MPEG
to obtain the DVD program version number, which appears on the
LCD as “DVD Ver: XXX”.
3. AMP TEST Mode
3.1. Outline
In this test mode, all controls except volume control function the same
as when the power normally turns on.
The volume increases or decreases in four steps (0, 1, 24 and 40).
3.2. TEST Mode Operation
1. In the test mode, the power turns on with DIGITAL 2 active. The
DIG2 function key code is sent to turn on the AMP side with DIG2.
2. The volume is 24 (-16 dB) and the surround mode is stereo mode,
which is selected when the DIG2 key code is sent.
3. The volume increases or decreases in four steps (0, 1, 24 and 40)
when the volume control button is pressed. Also in this test mode,
the maximum volume is set to -3dB depending on the surround
mode and audio format (refer to “Volume Control” and setting of
DSP trim value is processed (refer to “2-12-9-3. LEVEL setting” in
the same way as the normal operation.
First, the VOL1 value is sent to AMP.
4. “AMP TEST” appears in the 8-digit display field in the lower part of
the LCD for 3 seconds and switches to “DIGITAL 2” (message con-
tinues to switch in the same way as the normal operation).
• When an error occurs, a message remains until the error is
solved.
5. When the power button is pressed, the test mode is exited.
The volume setting returns to the default next time the micropro-
cessor starts up (other settings remain).
4. KEY TEST Mode
4.1. Outline
This test mode is to make sure the system microprocessor recognizes
keys on the main unit correctly.
4.2. TEST Mode Operation
1) When entering the test mode, all LEDs on the main unit light for 3
seconds.
2) A key code KEY TEST is sent to AMP to start it up.
3) When the POWER button is pressed and the power turns off, all of
65 x 65 dots on the LCD light for 10 seconds and the test mode is
canceled.
5. TUNER TEST Mode
5.1. Outline
In this test mode, the power turns on as it normally does and the tuner
function is activated. Settings are the same as in the normal operation.

6) When the “MUTING” button is pressed, the process returns to step
1.
7. Software rewrite test mode by EEPROM
In this test mode, settings can be adjusted for rewriting (patching) the
software on the DVD and AMP sides by EEPROM.
For software rewrite on the DVD side, the SYS_EEPROM_TEST key
code is sent to the AMP side and the system microprocessor enters
the rewrite mode.
For software rewrite on the AMP side, the AMP_EEPROM_TEST key
code is sent to the AMP side. The system microprocessor turns on, but
the DVD and changer do not function.
SYS side:
When entering the S.EEPROM MENU test mode (after the play button
is pressed), “S_EEPROM WAIT” appears. “WAIT” flashes at 1 Hz
when data is transferred from a PC.
After the transfer, “S.EEPROM COMP” appears. If an error occurs,
“S.EEPROM ERR” appears.
AMP side:
When entering the A.EEPROM MENU test mode (after the play button
is pressed), “A_EEPROM WAIT” appears and the indicator LED lights.
“WAIT” lights at 1 Hz when data is transferred from a PC (the indicator
LED also flashes at 1 Hz).
After the transfer it will directly go to POWER OFF mode.
If on error occurs, A.EEPROM WAIT will remaining display and the
indicator LED flashes at 2 Hz.
8. DVD FACTORY RESET test
8.1. TEST Mode Operation
1) The power turns on with the DVD function active, and the normal
DVD unit startup process is performed. “F.RESET” appears.
2) When the DVD Walk-up data (0x86) is received from ESS, the
[Factory Reset] command (0x7A) is sent to ESS three times.
3) Then the program version is sent to the system, which appears on
the LCD for at least 2 seconds as “DVD Ver:XXX” Refer to minute
data (0 x 21) and second data (0 x 22) from MPEG to obtain the
DVD program version number.
4) “COMPLETE” appears on the LCD for 1 second.
5) The DVD unit is turned off and then the power turns off.
8.2. Supplementary Note
1. Send Factory reset command to ESS then you can see something
like “VER:4.1.31.1S-USA00x” on the TV screen. The last 3 digit
00x means firmware version.
For example, 001=Ver#0.01, 101=Ver#1.01 etc.)
The same data as “title (41)”, “chapter (31)”, “minute (00)”, “second
(0x)” will be sent to system micom side.

[4] Description on the Circuits of the 1-Bit
Unit (See the wiring diagrams on pages 6-
21, 6-22.)
1. Input Part
Signals input from BIA201 are input to the AD conversion IC (ICA100,
ICA200 and ICA300) coupled by “CA100, CA200 and CA300” and
“CA101, CA201 and CA301”.
2. Modulation 1-Bit Converter
Signals input to the AD conversion ICs (ICA100, ICA200 and ICA300)
are converted into 1-bit signals for differential output. For detailed
description of the conversion into 1-bit signals, refer to the Technical
Manual for SM-SX100 already published.
3. Low Pass Filter Circuit
The 1-bit signals switched at the output ICs (ICA101, ICA102, ICA201,
ICA202, ICA301 and ICA302) are converted into analog signals by
passing through the low pass filter consisting of LA104 to LA107,
LA204 to LA207, LA304 to LA307 and CA114 to CA117, CA214 to
CA217, CA314 to CA317.
The property of low pass filter is flat up to 20 kHz and attenuated at
approx. 40 kHz by approx. 3 dB.
4. Dynamic Feedback Circuit
The 1-bit signals switched at the output ICs (ICA101, ICA102, ICA201,
ICA202, ICA301 and ICA302) are amplified between plus power and
GND.
By resistive division, the 1-bit signals pass through 75 kΩof NF resis-
tance (RA155 to RA158, RA255 to RA258, RA355 to RA358) and are
fed back to the AD conversion IC (ICA100, ICA200, ICA300). P-P volt-
age at this time is approx. 5 V.

[5] Confirming and Canceling the Detection
Line of the Protect Circuit
1. When power is on, the microcomputers (IC701) installed in this
model continuously monitor the following abnormal operations. If
any abnormality occurs, all power except for the circuit driving
these microcomputers are cut off immediately.
1) An abnormal drop in the regulator output voltage.
(Power cut off immediately without any display when the voltage
falls below approx. 1.5 V.)
2) Excessive output offset of the 1-bit amplifier.
(Power cut off immediately after direct current potential exceeds
approx. 2 V.)
3) Excessive main power supply current of the 1-bit amplifier.
(Power cut off immediately without any display when direct cur-
rent exceeds approx. 5.5 A.)
4) Abnormalities detected in the cooling fan motor and its drive cir-
cuit. (Stop, etc.)
Power cut off after “FAN LOCK” displayed.
2. How the microcomputers judge abnormalities and confirming and
canceling the detection line.
Conditions:
1) Abnormalities detected according to the voltages on pin 91 of
IC701 (PROTECT).
2) An abnormality detected when pulse signals input to pin 93
(FAN LOCK) of IC701 are lost for 5 sec.
3. Confirming and canceling the detection line.
CAUTION: Even if abnormalities mentioned in steps 1) and 2) above
are detected, the microcomputers do not operate protec-
tion when their PROTECT lines are cut off. In the case of
abnormalities caused by short circuit of the regulator, parts
or PWBs may burn out. Do not cut off the detection line if
short circuit is not detected.
1) If an abnormal drop in the regulator output voltage is detected,
connect the measuring instrument (the oscillograph, etc.) to the
regulator stabilized output and then turn on the power of the set.
When the output voltage is significantly lower than the stabilized
output voltage shown in the circuit diagram, the regulator itself
and its destination circuit are doubtful.
2) Excessive output offset of the 1-bit amplifier is detected, remove
CNPA402 and then turn on the power of the set for normal oper-
ation.
• After repairing, adjust the output offset voltage of the 1-bit
amplifier.

<Detail>
1. When DC level is unbalance between Lch and Rch, transistor
QA409 turn on and drive , circuit.
Unbalance Condition:
Normally, QA409 “B” and “E” is same voltage.
When one SP OUTPUT (R+, R-, L+ or L-) is short to chassis, -1,
-2 point voltage is half (1/2 x SP OUTPUT DC LEVEL).
So, QA409 turn on.
When Lch and Rch are short to chassis at same time, this circuit
don’t work.
Because unbalance condition is not happened.
2. When VBB line current is so much, resistor RA415 voltage drop is
much.
So, QA400 turn on.
3. Posistor PSA405 resistance value increase at high tempature.
So, DA415 anode voltage is decreased.
4. Refer to CHART “1”
This is normal timing chart at 1-bit amp. part of AS10.
SP OUTPUT DC LEVEL is about 0V →6V →20V at timing A →B
→C, D.
This circuit work at timing A →B change.
This timing is speaker output short to chassis before power on.
Speaker output is only (L-) and (R-).
(L+) and (R+) is through speaker relay point.
So, no concern this short at power on timing.
When short to chassis, DC level is unbalance at timing B.
Circuit QA409 drive circuit .
QA422 ON > QA421 OFF > QA420 ON > ICA100 RESET (21 pin)
low > SLA5515 output FET OFF > Short current OFF.
“QA420 ON” continue until “1-BIT PROTECT” able timing, then
µcom detect “1-BIT PROTECT” is low, then µcom change into
power off mode.
5. Refer to CHART “1”
This is normal timing chart at 1-bit amp. part of AS10.
SP OUTPUT DC LEVEL is about 0V →6V →20V at timing A →B
→C, D.
This circuit work at timing D.
This timing is speaker output short to chassis or other polarity out-
put after speaker relay on.
When short to chassis. DC level is unbalance at timing D.
Circuit QA409 drive circuit .
When short to other polarity output, VBB line current is so much.

QA423 ON > Pull QA408 BASE current – – – This circuit is latch.
When QA424 change off, this latch circuit keep “QA408 ON &
QA423 ON”.
So, “QA420 ON > ICA100 RESET (21 pin) low > SLA5515 output
FET OFF > Short current OFF” is keeped.
Then µcom detect “1-BIT PROTECT” by QA410 or QA420 and
change into power off mode.
This circuit work is controlled by QA427 & QA411.
+D5V is supplied at speaker relay on only. Because prevent fault
action.
Circuit protect response is faster than µcom “1-BIT PROTECT”
detection.
µcom “1-BIT PROTECT” detection expend long time.
6. When set temperature rise, circuit work to drive circuit
QA412.
QA412 ON > QA413 ON > µcom detect “PROTECT” > µcom
change into power off.
<Attention>
: Don’t mistake capacitor CA193, CA192 0.001µF.
When capacitance is more large, response is delay.
Can’t PROTECT IC.
/ : Confirm fault action at high temperature aging.
Don’t work at aging.
This circuit work at abnormal condition.
: Confirm work at (L-) or (R-) short to chassis.
: Confirm work at short after speaker relay on.
Confirm latch circuit – – – We already confirmed this circuit by your
DC voltage information (Result is OK).
