IMPORTANT SERVICE NOTES (FOR U.S.A. 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.

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.

Troubleshooting Chart

Many potential "problems" can be resolved by the owner without calling a service
technician.
If something is wrong with this product, check the following before calling your autho­rized SHARP dealer or service center.

General

CD player

Tuner

Cassette deck

Remote control

Condensation

Symptom Possible cause

The clock is not on time. Did a power failure occur? Reset the clock.
When a button is pressed, the unit

does not respond.

Set this unit to the power stand-by mode and
then turn it back on.

If the unit still malfunctions, reset it. (Refer to
step 3 under "If trouble occurs")

No sound is heard. Is the volume level set to "0"?

Are the headphones connected?
Are the speaker wires disconnected?

Symptom Possible cause

Playback does not start. Is the disc loaded upside-down?
Playback stops in the middle or is not

performed properly.

Does the disc satisfy the standards?
Is the disc distorted or scratched?

Playback sounds are skipped, or
stopped in the middle of a track.

Is the unit located near excessive vibrations?
Is the disc very dirty?
Has condensation formed inside the unit?

Symptom Possible cause

Radio makes unusual noise con­secutively.

Is the unit placed near the TV or computer?
Is the FM/AM loop antenna placed properly?

Move the AC power cord away from the an­tenna if located near.

Symptom Possible cause

Cannot record. Is the erase-protection tab removed?
Cannot record tracks with proper

sound quality.

Is it a normal tape? (You cannot record on a

metal or CrO tape.)
Cannot erase completely.
Sound skipping. Is there any slack?

Is the tape stretched?
Cannot hear treble. Are the capstans, pinch rollers, or heads

dirty?
Sound fluctuation.

Cannot remove the tape. If a power failure occurs during playback, the

heads remain engaged with the tape. Do not

open the compartment forcibly. Wait until

electricity resumes.

Symptom Possible cause

The remote control does not oper­ate.

Is the AC power cord of the unit plugged in?

Is the battery polarity respected?

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is
compensated inside the IC.)

* Focus offset adjustment
* Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing

Fig.14-2 EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will
be 0 dB.)

* Focus gain adjustment
* Tracking gain adjustment

• Adjustment
Since this CD system incorporates the following automatic
adjustment 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
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.

• The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas­sis with no signal given.

1. In the tuner section,

( ) indicates AM
< > indicates FM stereo

2. In the main section, a tape is being played back.

3. In the deck section, a tape is being played back.

( ) indicates the record state.

4. In the power section, a tape is being played back.

5. In the CD section, the CD is stopped.

• Parts marked with “ ” ( ) are important for
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.

NOTES ON SCHEMATIC DIAGRAM

• Resistor:
To differentiate the units of resistors, such 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
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.

• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pico-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

• Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
notice.

1. CD optical pickup Lens cleaner disc UDSKA0004AFZZ

TROUBLE SHOOTING

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 trouble shooting 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.

When a CD cannot be played

1. "E-CD01" is displayed.

(1) Check the power to IC1 (LC78645E), the presence of the clock signal (33.8688 MHz) and the status of the RESET terminal
(pin 66 on IC1).
(2) Does the pickup move to the PICKUP-IN Switch (SW4) position?

If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).

2. Pressing the CD operation key is accepted, but playback does not occur.

(1) Focus-HF system check
(2) Tracking system check
(3) Spin system check
(4) PLL system check

Is pin 52 (C2F) on IC1 "L" ?

Yes

No

The HF waveform is normal and the time is displayed
normally, but no sound is produced. Or the sound
has dropouts.

(5) Others

There are too many error flags on a damaged disc which
makes error correction impossible.

Check again using a known good disc.

1. When playing at normal speed
Check the peripheral circuit at pin 39 (DOUT) on IC1 and
the waveform (Figure 42-2).

If OK, Check the unit.

When a disc is loaded, start play operation.

(4) PLL system check

The HF waveform is normal, but the TOC data cannot be
read.

Check the PDO waveform. (Figure 42-1)

Check around pins 73~78 on IC1.
