Notes on chip component replacement

•Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 ˚C dur­ing repairing.

• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering
or unsoldering.

SAFETY CHECK-OUT

After correcting the original service problem, perform the follow­ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA

WT -540A. Follo w the manufacturers’ instructions to use these
instruments.

2. A battery-operated AC milliammeter. The Data Precision 245

digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The “limit” indica­tion is 0.75 V, so analog meters must have an accurate low­voltage scale. The Simpson 250 and Sanwa SH-63T rd are ex­amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2 V A C range are suit­able. (See Fig. A)

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra­diation exposure.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 ˚C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 ˚C.
Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges oc­cur such as on IC pins, etc.

• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

Using the AC power adaptor

•When operating the unit with an external power source, do not remove the
batteries.
These batteries serve to backup the clock and memory settings. Since the
batteries discharge in this case as well, we recommend changing them about
once a year.

•To pre vent battery leakag e, we recommend removing the batteries when the
unit is connected to a wall outlet.

• Before connecting and disconnecting the external power source plug, be
sure to turn off the radio/CD. Otherwise, “E ” may be displayed. When this
occurs,turn on the radio/CD so that “E ” disappears..

•When the A C power adaptor is not to be used for a long period of time,unplug
it both from the DC IN 6 V jack and from the wall outlet.

•When the cover of the DC IN 6 V jack is open (to use the AC power adap­tor), the jack area is not splash-resistant. When the AC power adaptor is not
connected to the DC IN 6 V jack, be sure to close the cover of the DC IN 6
V jack.

• Use the recommended Sony AC poweradaptor * only. The polarity of the
plugs of other manufacturers may be different. Failure to use the recom­mended AC power adaptor may cause the unit to malfunction.

* Supplied with European model only

If you have any questions or problems concerning your unit,please consult
your nearest Sony dealer.

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro­static break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emis­sion, observe from more than 30 cm away from the objectiv e lens.

LASER DIODE AND FOCUS SEARCH OPERATION
CHECK

During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper lid is closed while turning ON
the S701. (push switch type)
The following checking method for the laser diode is operable.

• Method
Emission of the laser diode is visually checked.

1. Open the lid.

2. Push the S551 as shown in Fig.1.

3. Press the [CD ] button.

4. Check the object lens for confirming normal emission of the

laser diode. If not emitting, there is a trouble in the automatic
power control circuit or the optical pick-up.
In this operation, the object lens will move up and down 2
times along with inward motion for the focus search.

Perform all CD section check in the test mode.

FOCUS BIAS CHECK

Procedure:

1. Connect the oscilloscope to TP (RF) and TP (VC) on the CD
board.

2. Set the CD test mode. (Refer to CD TEST MODE (See page

11))

3. Insert the test disc (YEDS-18). (Part No. 3-702-101-01) (CD)

4. Press the [CD ] button. (LPC ON)

5. Confirm that the oscilloscope waveform is as shown in the
figure below. (eye pattern)
A good eye pattern means that the diamond shape (◊) in the
center of the waveform can be clearly distinguished.

6. Press the [CD ] button. (LPC OFF)

7. Perform confirmation in the same manner as step 5.

8. Press the [OFF ] button.

9. Change the test disc (TCD-W082L). (Part No. J-2502-063-2)
(CD-RW)

10. Perform confirmation in the same manner as step 4 to 7.
