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.
Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur-
ing 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.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous ra-diation exposure.
SAFETY-RELATED COMPONENT WARNING!!COMPONENTS IDENTIFIED BY MARK 0 OR DOTTEDLINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMSAND IN THE PARTS LIST ARE CRITICAL TO SAFEOPERATION. REPLACE THESE COMPONENTS WITHSONY PARTS WHOSE PART NUMBERS APPEAR ASSHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-LISHED BY SONY.
This appliance is classified asa CLASS 1 LASER product.The CLASS 1 LASERPRODUCT MARKING islocated on the rear exterior.
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 MARKUnleaded 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 viscou-s (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridges oc-cur 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.

SECTION 1SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-static break-down because of the potential difference generatedby the charged electrostatic load, etc. on clothing and the humanbody.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.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 focusedon the disc reflective surface by the objective lens in the opticalpick-up block. Therefore, when checking the laser diode emis-sion, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the S curve check in CD section adjustment andcheck that the S curve waveforms is output three times.

CD SECTIONNote:1. CD Block is basically designed to operate without adjustment. Therefore,
check each item in order given.2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.3. Use an oscilloscope with more than 10M impedance.4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
S-CURVE CHECK
Procedure :1. Connect an oscilloscope to TP (FE) and TP (VC) on the CD
board.2. Press the I/1 button to turn the power ON.3. Load a disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focussearch)
4. Confirm that the oscilloscope waveform (S-curve) issymmetrical between A and B. And confirm peak to peak levelwithin 3 0.5 Vp-p.
Note: Try to measure several times to make sure than the ratioof A : B or B : A is more than 10 : 7.
Take sweep time as long as possible and light up thebrightness to obtain best waveform.
Connecting Location: CD board
RFAC LEVEL CHECK
Procedure :1. Connect an oscilloscope to TP (RFACO) and TP (VC) on the
CD board.2. Press the I/1 button to turn the power ON.3. Load a disc (YEDS-18) and playback.4. Confirm that oscilloscope waveform is clear and check if RFAC
signal level is correct or not.Note: Clear RFAC signal waveform means that the shape can be
clearly distinguished at the center of the waveform.
