CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
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 damaged by heat.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH
MARK !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.
* Replacement of CXD2671-201GA (IC601) used in this set
requires a special tool.

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.

TEST MODE
4-1. GENERAL
Remote control LCD
• When entered in the TEST MODE, this set provides the Overall
Adjustment mode which allows CD and MO discs to be automatically 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.

When method 1 was 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 2 was 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)

For further information, refer to section 5. ELECTRICAL ADJUSTMENTS. (See page 11)
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.
