SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR 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.
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.
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.
On AC poweradaptor
•Use only the commercially-available AC power adaptor whose rated output is 4.5 V DC, 500 mA. Do not use any other AC power adaptor. It may cause a malfunction.

SECTION 1
SERVICING NOTE
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown 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.
BEFORE REPLACING THE OPTICAL PICK-UP BLOCK
Please be sure to check thoroughly the parameters as par the “Optical Pick-Up Block Checking Procedures” (Part No.: 9-960-027-11) issued separately before replacing the optical pick-up block.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S301. (push switch type)
The following checking method for the laser diode is operable.
•Method:
Emission of the laser diode is visually checked.
1.Open the upper lid.
2.With a disc not set, turn on the S301 with a screwdriver having a thin tip as shown in Fig.1.
3.Press the u button.
4.Observing the objective lens, check that the laser diode emits light.
When the laser diode does not emit light, automatic power control circuit or optical pickup is faulty.
In this operation, the objective lens will move up and down 4 times along with inward motion for the focus search.

(LCD display on the remote control is not changed.)
Note : Be sure to keep your eyes apart from the direct emission of the Laser diode.
Do not move the optical pick-up over outermost or innermost.
• CD-DA/RW Change Over Function
By short pressing the > button on the set or the > button on the remote control, the terminal control for gain control is changed and gain for playing of CD-DA or CD-RW is changed over.
(LCD display on the remote control is not changed.)
• Focus Search Mode
By short pressing the [VOL+] button on the set or the [VOL+] button on the remote control, focus search is performed.
• Laser ON/OFF Selection Function
By short pressing the [VOL-] button on the set or the [VOL-] button on the remote control, laser is switched on or off.
Note : Be sure to keep your eyes apart from the direct emission of the Laser diode.
• Menu Mode
By short pressing the x button on the set or the x button on the remote control, the Menu mode is activated. The menu mode is not used for service, therefore press the x button on the set or the x button on the remote control for short time to exit this mode. (TOC is displayed)
4.Operations by buttons or Rotary control in the Service Mode
(Play status)
Note : u / x / > / . buttons are available.
• Tracking/Sled Servo ON/OFF Change Over Function
By short pressing the [VOL+] button on the set or the [VOL+] button on the remote control during play back, Tracking/Sled Servo is switched on or off.
(Track number is displayed on the LCD display.)

XP-ZV71/ZV71C/ZV77/ZV77D
• Microcomputer Halt Function
By short pressing the [VOL-] button on the set or the [VOL-] button on the remote control during play back, the operation of the microcomputer is stopped.
After the microcomputer stopped, any key operation or display operation is not performed. Communication with the DSP is not performed. This mode is used only for checking the operation/ function of servo.
(LCD on the remote control is lit off)
Note : To exit this mode , switch off and then switch on.
5. How to exit the Service Mode
1)Turn off the power.
2)Open the solder land SL302 (TEST) on the MAIN board. Note : The solder should be removed clean.
