SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITHMARK ! ON THE SCHEMATIC DIAGRAMS AND IN THE PARTSLIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR INSUPPLEMENTS 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 setrequires a special tool.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardousradiation exposure.
• UNLEADED SOLDERBoards requiring use of unleaded solder are printed with thelead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printedwith 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 tobe applied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be setto about 350°C.Caution: The printed pattern (copper foil) may peel away ifthe heated tip is applied for too long, so be careful!
• Strong viscosityUnleaded solder is more viscous (sticky, less prone toflow) than ordinary solder so use caution not to let solderbridges occur such as on IC pins, etc.
• Usable with ordinary solderIt is best to use only unleaded solder but unleaded soldermay 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 MODEWhen method 1 was used:Turn off the power and open the solder bridge on TAP601 on themain 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 cannotstart 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 systemdiscriminates between CD and MO discs, performs adjustmentsin sequence automatically, and displays the faulty location ifany fault is found. In the Manual mode, selected adjustmentscan 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 theremote control.
4-2. SETTING THE TEST MODE4-2-1. How to set the TEST MODETo set the TEST MODE, two methods are available.1 Solder bridge and short TAP601 (TEST) on the main board.
Then turn on the power.
MAIN BOARD (SIDE A)
2 In the normal mode, operate the keys on the set and those on theremote 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 thefollowing sequence: > N t > N t . t . t > N
t . t > N t . t X t X
4-2-2. Operations when the TEST MODE is setWhen the TEST MODE is entered, the system switches to the dis-play check mode within the TEST MODE. From this mode, theother 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. The100th place is a major item, 10th place is a middle item, and unitplace 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 x key.
4-5. OVERALL ADJUSTMENT MODE
4-5-1. Outline of the functionThis mode is designed to adjust the servo system automatically bygoing through all the adjustment items.Usually, this mode is used to perform automatic adjustments whenservicing the set.
For further information, refer to section 5. ELECTRICAL ADJUST-MENTS. (See page 12)
4-6. SELF-DIAGNOSTIC DISPLAY MODE
4-6-1. Outline of the functionThe Self-diagnostic system is used in this set. If an error occursduring playback, this system detects the fault through themicroprocessor’s mechanism and power control blocks and storesthe cause in EEPROM in a history format.This history, which can be viewed in the TEST MODE, providesthe means of locating the fault in troubleshooting.
4-4. MANUAL MODE
4-4-1. Outline of the functionThe Manual mode is designed to perform adjustments andoperational checks on the set’s operation according to eachindividual function.Usually, no adjustments are made in this mode.However, the Manual mode is used to clear the memory beforeperforming automatic adjustments in the Overall Adjustment mode.
4-4-2. How to set the Manual mode1. Set the TEST MODE and press + key to set the Manual mode.

Note on Schematic Diagram: MAIN SECTION
• All capacitors are in µF unless otherwise noted. pF: µµF50 WV or less are not indicated except for electrolyticsand tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specified.• f : internal component.
Note: The components identified by mark 0 or dottedline with mark 0 are critical for safety.Replace only with part number specified.
• : B+ Line.• Power voltage is dc 1.5V and fed with regulated dc power
supply from battery terminal.• Voltages and waveforms are dc with respect to ground
under no-signal conditions.no mark : PLAY
• Voltages are taken with a VOM (Input impedance 10 MΩ).Voltage variations may be noted due to normal produc-tion tolerances.
• Waveforms are taken with a oscilloscope.Voltage variations may be noted due to normal produc-tion tolerances.
• Circled numbers refer to waveforms.• Signal path.
F : AnalogJ : Digital
• Replacement of IC601 used in this set requires a specialtool.
• The voltage and waveform of CSP (chip size package)cannot be measured, because its lead layout is differentform that of conventional IC.
Note on Printed Wiring Boards: MAIN SECTION
• X : parts extracted from the component side.• : Pattern from the side which enables seeing.(The other layers' patterns are not indicated.) Caution:
Pattern face side: Parts on the pattern face side seen from the(Side B) pattern face are indicated.Parts face side: Parts on the parts face side seen from the(Side A) parts face are indicated.
• Main boards is four-layer pritnted board.However, the patterns of layer 2 and 3 have not beenincluded in this diagrams.
