SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK !OR DOTTED LINEWITH

LIST ARE CRITICALTO SAFE OPERATION.
REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE
PART NUMBERS APPEAR AS SHOWN INTHIS MANUAL OR IN
SUPPLEMENTS PUBLISHED BY SONY.
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 chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
TABLE OF CONTENTS
* Replacement of CXD2671B-206GA (IC601) used in this set
requires a special tool.
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
lead-free 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 viscous (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.
MAIN BOARD SUB ASSY
• Audio board is supplied with main board sub ASSY.
• Audio board can not be moved away from main bord.Give a
damage when take it off forcibly.
• The part that audio board overlap with main board can not be
repaired.

4-2-3. How to release the TEST MODE
When method 1was used:
Turn off the power and open the solder bridge on TAP601 on the
main board.
Note: The solder should be removed clean. The remaining solder
may make a short with the chassis and other part.
When method 2was used:
Turn off the power.
Note: If electrical adjustment (see page 11) has not been finished
completely, always start in the test mode. (The set cannot
start in normal mode)
4-3. TEST MODE STRUCTURE
4-1. GENERAL
• When entered in the TEST MODE, this set provides the Overall
Adjustment mode which allows CD and MO discs to be auto-
matically adjusted. In the Overall Adjustment mode, the system
discriminates between CD and MO discs, performs adjustments
in sequence automatically, and displays the faulty location if
any fault is found. In the Manual mode, selected adjustments
can be performed automatically.
• The attached remote control is used to operate the TEST MODE.
Unless otherwise specified in the text, the key means that on the
remote control.
4-2. SETTING THE TEST MODE
4-2-1. How to set the TEST MODE
To set the TEST MODE, two methods are available.
1Solder bridge and short TAP601 (TEST) on the main board.
Then turn on the power.
MAIN BOARD (SIDE A)
2In the normal mode, operate the keys on the set and those on the
remote control as specified below:
Turn on HOLD switch on the set. Holding down x (STOP)
key on the set, press the keys on the remote control in the
following sequence:
> N t> N t.t.t> N
t.t> N t.tXtX
4-2-2. Operations when the TEST MODE is set
When the TEST MODE is entered, the system switches to the dis-
play check mode within the TEST MODE. From this mode, the
other Test modes can be accessed.
When the TEST MODE is set, the LCD repeats a cycle of the fol-
lowing displays:

3. Each test item is assigned with a three-digit item number. The
100th place is a major item, 10th place is a middle item, and unit
place is a minor item.
Note: In the Power mode, the item title display is only displayed.
5. To terminate the Manual mode and return to the TEST MODE,
press xkey.
4-5. OVERALL ADJUSTMENT MODE
4-5-1. Outline of the function
This mode is designed to adjust the servo system automatically by
going through all the adjustment items.
Usually, this mode is used to perform automatic adjustments when
servicing the set.
For further information, refer to section 5. ELECTRICALADJUST-
MENTS. (See page 12)
4-6. SELF-DIAGNOSTIC DISPLAY MODE
4-6-1. Outline of the function
The Self-diagnostic system is used in this set. If an error occurs
during playback, this system detects the fault through the
microprocessor’s mechanism and power control blocks and stores
the cause in EEPROM in a history format.
This history, which can be viewed in the TEST MODE, provides
the means of locating the fault in troubleshooting.
4-4. MANUAL MODE
4-4-1. Outline of the function
The Manual mode is designed to perform adjustments and
operational checks on the set’s operation according to each
individual function.
Usually, no adjustments are made in this mode.
However, the Manual mode is used to clear the memory before
performing automatic adjustments in the Overall Adjustment mode.
4-4-2. How to set the Manual mode
1. Set the TEST MODE and press + key to set the Manual mode.
