SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINEWITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTSWHOSE PART NUMBERS APPEAR AS SHOWN IN THISMANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardousradiation 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.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNITThe laser diode in the optical pick-up block may suffer electrostaticbreakdown because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic breakdown and also usethe procedure in the printed matter which is included in the repairparts.The flexible board is easily damaged and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.

•UNLEADED SOLDERBoards 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 beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 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 bridgesoccur such as on IC pins, etc.
• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

LASER DIODE AND FOCUS SEARCH OPERATIONCHECK
1. Turn ON the [POWER] or [OPERATE] button and press [CD]button to CD position.
2. Open the CD lid.3. Turn on S801 with screwdriver, etc. as following figure.4. Press the N X (CD) button.5. Confirm the laser diode emission while observing the objecting
lens. When there is no emission, Auto Power Control circuitor Optical Pick-up is broken.Objective lens moves up and down three times for focus search.
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the lid (CD), useChuck Plate Jig.

Example of folder structure and playingorderThe playing order of the folders and files is as follows:
Notes• A folder that does not
include an MP3 file isskipped.
• Maximum number offolders: 255Maximum number of files:255
• Folder names and filenames can be displayedwith up to 64 characters.
• The characters A - Z, a - z,0 - 9, and _ can bedisplayed on this player.Other characters aredisplayed as “*”.
• This player conforms toVersion 1.1 of the ID3 tagformat. If the file has theID3 tag information, “songtitle”, “artist name” and“album name” can bedisplayed.
About CD-Rs/CD-RWs and MP3 filesThis player can play CD-Rs/CD-RWs recorded in the CD-DA format* and MP3 files recorded in the CD-ROMformat, but playback capability may vary depending on thequality of the disc and the condition of the recordingdevice.* CD-DA is the abbreviation for Compact Disc Digital Audio. It is
a recording standard used for Audio CDs.

FOCUS BIAS CHECK1. Connect the oscilloscope between IC701 pin 4 and pin qa
(or TP (RF) and TP (VREF)).2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)3. Press the N X (CD) button.4. Confirm that the oscilloscope waveform is as shown in the
figure below. (eye pattern)A good eye pattern means that the diamond shape ( ) in thecenter of the waveform can be clearly distinguished.
When observing the eye pattern, set the oscilloscope for AC rangeand raise vertical sensitivity.
