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.
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 PARTS WHOSE
PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR
IN SUPPLEMENTS PUBLISHED BY SONY.

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.

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 horizontal as possible.
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.

Speaker System Connections
Speaker Positioning
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.).
For a normal setup use 6 speakers (2 front speakers,
center speaker, 2 rear speakers and subwoofer).
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.
Front Speaker
(Right)
Center
Speaker
•
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.

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.
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.

(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.
