Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.

This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.

CAUTION

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

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.

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)

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE
WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN
THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.
REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE
PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR
IN SUPPLEMENTS PUBLISHED BY SONY.

: 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.

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. Follow the manuf acturers’ instructions to use these
instruments.

2. A battery-operated A C 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 v oltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-v oltage
scale. The Simpson 250 and Sanwa SH-63Trd 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)

To Exposed Metal
Parts on Set

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 pick­up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

LASER DIODE AND FOCUS SEARCH OPERATION
CHECK

Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveform is output several times.

2. Previous Preparation for Deck Adjustment

(Preparation to load the VCR (VCP) with cassette tape not inserted)

1) Take the power cord from the consent.

2) Separate the top cover and the plate assembly top.

3) Insert the power cord into again.

4) Turn the VCR (VCP) on and load the cassette while push­ing the lever stopper of the holder assembly CST back­ward. In this case, clog both holes on the housing
rail part of chassis to prevent detection of the end sensor.

3. Torque Measuring

Purpose of Measuring : To measure and check the reel torque on the take-up part and the

supply part that performs basic operation of the VCR (VCP) for
smoothly forwarding the tape.
Measure and check followings when the tape is not smoothly
wound or the tape velocity is abnormally proceeded:

If doing so, proceeding to the stop mode is done. In this
status, input signals of all modes can be received.
However, operation of the Rewind and the Review is
impossible since the take-up reel remains at stop status
and so cannot detect the reel pulse (however, possible for
several seconds).

VCR (VCP) status Measuring methodFixtures and tools used

• Torque Gauge
(600 g.cm ATG)

• Torque Gauge Adaptor

• Cassette Torque Meter
SRK-VHT-303

• Play (FF) or Review

• Try to operate the VCR (VCP) per mode with the
tape not inserted (See ‘2. Prior Preparation for
Deck Adjustment).

• Measure after adhering and fixing the torque
gauge adaptor to the torque gauge (Fig. C-3-1)

• Read scale of the supply or take-up part of the
cassette torque meter (Fig. C-3-2).

Adjustment Procedure/Adjustment Diagrams

1) Basically use the A/C head assembly adjusted as in
SPEC.

2) Check there is crumpling and folding of the tape around
the A/C head. If it is, Turn and adjust the tilt adjusting
screw to ensure that the tape corresponds to the bottom
guide of the P4, and recheck the tape path after pro­ceeding play for 4-5 seconds.

• Azimuth adjusting screw (A)

3) Where the tape bottom is not equal to Fig. C-5-3, Adjust
the height by using the height adjusting screw (B) and
then readjust it by using the tilt adjusting screw (C).

CAUTIONS

Always check the height of the A/C head since most ideal
height of A/C head can be obtained when the bottom part
of the tape is away 0.2 ~ 0.25mm from the bottom part of
the A/C head.

envelope level to the maximum point and then fix the fix­ing screws.

2) For the 31mm head, adjust it with the SP tape recorded
in the width of 31mm since the head travels on the tape
track only for SP with the width of 58mm.

5-2. Tape Path Check between Pinch Roller and

Take up Guide (Check in the Rev Mode)

1) Check the tape pass status between the pinch roller and
the take-up guide.(Check there is crumpling of the tape
pass and folding of the take-up guide.)

1) (1) When holding of the take-up guide bottom occurs

Turn the tilt adjusting screw (C) clockwise and travel it
stably to ensure there is no crumbling or folding of the
tape.

1) (2) When holding of the take-up guide top occurs

Turn the tilt adjusting screw (C) anti-clockwise and

travel it stably to ensure there is no crumbling or fold­ing of the tape.

1) 2) Check there is folding of the tape at the bottom or top

of the take-up guide in cutting-off the REV mode

CAUTIONS

If the RF waveform is changed after adjusting the A/C head,
perform fine adjustment to ensure the RF waveform is flat­tened.

Adjustment Procedure

1) Connect the probe of Oscilloscope to the audio output
jack.

2) Ensure that Audio 1KHz, 7KHz output is flattened at the
maximization point by adjusting the Azimuth adjusting
screw (A).

1. Checking Points prior to Repair

Following abnormal phenomena may be repaired by
removal of foreign materials and oil supply. Check oiling is
required at the checking set or cleaning status is complete.
Determine that necessity of checking and repair the set
exists after checking the using period of the set together
with the user. In this case, followings must be checked:

2. Essential Check and Repair

Recording density of the video is far higher than the audio.
Therefore video parts are very precise so as to allow only
error of 1/1000mm or so in order to maintain compatibility
with other videos.
If one of these parts is polluted or old, same phenomena will
appear as they are damaged.
To maintain clear screen, regular check, replacement of old
and damaged parts and oil supply, etc are essential.

3. Regular Check and Repair

Check and repair schedule is not constant since they vary
depending on method that the consumer uses video and
environment where the video is installed at.
However, for the video used by common household, good
screen will be maintained if regular check and repair per
1,000 hour is performed. The following chart shows relation­ship between using time and checking time:

(Green)
(2) Grease: Kanto G-754, PL-433 (Yellow)
(3) Alcohol (Isopropyl Alcohol)
(4) Cleaning Patch (cloth)

5. Maintenance Process

5-1) Removal of Foreign Material

(1) Removal of foreign material from video head (Fig. C-9-4)

Firstly try to use a cleaning tape.

(1) Use a cleaning patch if foreign materials are not removed

with the cleaning tape due to severe dirty of the head.

Soak the cleaning patch in alcohol and put it to the head

tip. Smoothly turn the drum (turning cylinder) to the right

or left (In this case, the cleaning patch must not be

moved vertically).

(1) After completely drying the head, test the traveling status

of the tape.

(1) If alcohol (Isopropyl Alcohol) remains at the video head,

the tape may be damaged when this solution touches

with the head surface.

Never use a cloth bar (commercial sale)

(2) Wipe the tape transport system and the drive system

with the cleaning patch soaked in alcohol (Isopropyl

Alcohol) when removing foreign materials from them.

1) The part touched with the traveling tape is called as
tape transport system. The drive system consists of
parts to travel the tape.

(2) 2) Care must be exercised so that unreasonable force

to change the pattern will be applied to the tape trans­port system during removal of foreign materials.

5-2) Grease Applications

(1) Grease Application Method

Apply grease by using a cloth swab or brush. Care must
be exercised so that excess quantity should not be
used. If the excessive quantity is applied, wipe it with
the gauze soaked in alcohol (Isopropyl Alcohol).

NOTE: POSITION OF GREASE APPLICATION
