AVD-K150B/K150E/K150G/K150N/K150R

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.

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.

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.

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 P ARTS WHOSE
PART NUMBERS APPEAR AS SHOWN IN THIS MANU AL OR

Depending on your TV and other equipment you wish
to connect, there are various ways you could connect
the DVD/VCR Receiver. Use one of the connections
described below.

•

Please refer to the manuals of your TV, VIDEO,
Stereo System or other devices as necessary to
make the best connections.

Caution

− Make sure the DVD/VCR Receiver is connected
directly to the TV. Select the correct AV input on your
TV.

− Do not connect your DVD/VCR Receiver to TV via
your VIDEO. The DVD image could be distorted by
the copy protection system.

Basic connections (AV)

Connect the EURO AV1 (TO TV) on the rear panel

1

of the DVD/VCR Receiver to the scart input socket
on the TV using a SCART lead (E).

Some TV broadcasters transmit encoded television

2

signals which you can only see with a purchased or
rented decoder.You can connect such a decoder
(descrambler) to the DVD/VCR Receiver (D).

SCART INPUT

Basic connection (RF)

Connect the aerial cable (A) from your indoor/ out-

1

door aerial to ANTENA IN jack on the rear panel of
DVD/VCR Receiver.

Connect the supplied RF cable (R) from the

2

ANTENA OUT jack on the rear panel of DVD/VCR
Receiver to your television's Aerial Input.

Notes

When you connect the DVD/VCR Receiver to your TV,
be sure to turn off the power and unplug both units from
the wall outlet before making any connections.

Notes

• To prevent noise pickup, keep the AM loop antenna
away from the DVD/VCR Receiver and other compo­nents.

• Be sure to fully extend the FM wire antenna.

• After connecting the FM wire antenna, keep it as hori-

zontal as possible.

Digital Device Connections

Connect the OPTICAL IN jacks on the DVD/VCR
Receiver to the digital audio out (optical) jacks on your
digital device (Game device, Digital Set Top Box, etc.),
using optional optical audio cable.
To select source of DVD/VCR Receiver to OPTICAL IN,
press INPUT SELECT repeatedly on the remote control
until "AV3 OPT" appears in the display window.

Notes

• If the audio format of the digital output does not
match the capabilities of your DVD/VCR Receiver, the
DVD/VCR Receiver will produce a strong, distorted
sound or no sound at all.

• The Optical input function is available only when the
other unit's Sampling Frequency is 32 - 48kHz.

Accessory Audio/Video (A/V)
Connections to DVD/VCR Receiver

Connect the AV3 IN jacks on the DVD/VCR Receiver to
the audio/video out jacks on your accessory compo­nent, using optional audio/video cables.

Connections (Continued)

AVD-K150B/K150E/K150G/K150N/K150R

Speaker System Connections

Connect the speakers using the supplied speaker cords
by matching the colors of the terminals and those of the
cords. To obtain the best possible surround sound,
adjust the speaker parameters (distance, level, etc.).

Notes

• Be sure to match the speaker cord to the appropriate
terminal on the components: 3 to 3 and # to #. If

the cords are reversed, the sound will be distorted
and lack bass.

• If you use front speakers with low maximum input rat­ing, adjust the volume carefully to avoid excessive
volume output to the speakers.
Do not disassemble the front covers of supplied speakers.

Speaker

Front Speaker
(Left)

Speaker Positioning

For a normal setup use 6 speakers (2 front speakers,
center speaker, 2 rear speakers and subwoofer).

•

Front Speakers

Based on your listening position, set up the speakers
at equal distance. And by hearing position, set up an
interval between speakers of 45 degree.

•

Center Speaker

It is ideal that the center speakers and front speakers
are same height. But normally place it above or below
the television as shown below.

•

Rear Speakers

Place the rear surround speakers to the left and right
behind the primary listening area. These speakers
recreate sound motion and atmosphere required for
surround playback. For best results, do not install the
rear speakers too far behind the listening position,
install them at or above the level of the listenerês ears.
It is also effective to direct the rear speakers towards
a wall or ceiling to further disperse the sound.
In the case of a smaller room size, if the audience is
near to the rear wall set the rear speakers opposite
each other, and set the rear speakers 60 - 90 cm
above the listener's ears.

Subwoofer

This can be placed in any front position.

2. Preparation for Adjustment (To set the
Deck Mechanism of the loading state
without inserting a cassette tape).

1) Unplug the power cord from the AC outlet.

2) Disassemble the Top Cover and Plate Assembly Top.

3) Plug the power cord into the AC outlet.

4) Turn the power S/W on and push the Lever Stopper of
the Holder Assembly CST to the back for loading the

cassette without tape.
Cover the holes of the End Sensors at the both sides of
the Chassis to prevent a light leak.
Then the Deck Mechanism drives to the Stop Mode.
In this case, the Deck Mechanism can accept inputs of
each mode, however the Rewind and Review operation
can not be performed for more than a few seconds
because the Take-up Reel Table is in the Stop State
and can not be detected the Reel Pulses.

3. Checking Torque

2. Required Maintenance

The recording density of a VCR(VCP) is much higher than
that of an audio tape recorder. VCR(VCP) components must
be very precise, at tolerances of 1/1000mm, to ensure com­patibility with the other VCRs. If any of these components are
worn or dirty, the symptoms will be the same as if the part is
defective. To ensure a good picture, periodic inspection and
maintenance, including replacement of worn out parts and
lubrication, is necessary.

3. Scheduled Maintenance

Schedules for maintenance and inspection are not fixed
because they vary greatly according to the way in which the
customer uses the VCR(VCP), and the environment in which
the VCR(VCP) is used.
But, in general home use, a good picture will be maintained
if inspection and maintenance is made every 1,000 hours.
The table below shows the relation between time used and
inspection period.

5. Maintenance Procedure

5-1) Cleaning

(1) Cleaning video head

First use a cleaning tape. If the dirt on the head is too
stubborn to remove by tape, use the cleaning patch. Coat
the cleaning patch with Isopropyl Alcohol. Touch the
cleaning patch to the head tip and gently turn the
head(rotating cylinder) right and left.
(Do not move the cleaning patch vertically. Make sure
that only the buckskin on the cleaning patch comes into
contact with the head. Otherwise, the head may be dam­aged.)
Thoroughly dry the head. Then run the test tape. If lso­propyl Alcohol remains on the video head, the tape may
be damaged when it comes into contact with the head
surface.

(2) Clean the tape transport system and drive system, etc, by

wiping with a cleaning patch wetted with Isopropyl
Alcohol.

NOTES:

1 It is the tape transport system which comes into contact

with the running tape. The drive system consists of those
parts which moves the tape.

2 Make sure that during cleaning you do not touch the tape

transport system with excessive force that would cause
deformation or damage to the system.

5-2) Greasing

(1) Greasing guidelines

Apply grease, with a cleaning patch. Do not use exces­sive grease. It may come into contact with the tape
transport or drive system. Wipe excessive grease and
clean with cleaning patch wetted in Isopropyl Alcohol.
