COMPONENTS IDENTIFIED

4、BY MARK 0 OR 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 PUB- LISHED BY SONY. The laser diode in the optical pick-up block may suff

5、er electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The fle

6、xible 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 pick-up block. Therefore, when checking the laser diode emis- sion,

7、observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveforms is output three times. Notes on chip component replacement Never reuse a disconnected chip component.

8、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 app

9、ly force on the conductor when soldering or unsoldering. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. This appliance is classified as a CLAS

10、S 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. The following caution label is located inside the unit. RadioFans.CN 收音机爱 好者资料库 3 CDP-S3 TABLE OF CONTENTS 1.SERVICI

34、refore, check each item in order given. 2.Use LUV-P01 (4-999-032-01) 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 Ch

35、eck Procedure : 1.Connect an oscilloscope to TP (FEO). 2.Connect between TP (FEI) and TP (DVC) (1.65 V) by lead wire. 3.Turn Power switch on. 4.Load a disc (LUV-P01) and actuate the focus search. (In consequence of open and close the disc tray, actuate the focus search) 5.Confirm that the oscillosco

36、pe waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 2 0.5 Vp-p. 6.After check, remove the lead wire connected in step 2. Note : Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. Take sweep time as long as possible

37、and light up the brightness to obtain best waveform. RF Level Check Procedure : 1.Connect an oscilloscope CH1 to TP (RFDC) and CH2 to TP (RFAC). 2.Turn Power switch on. 3.Load a disc (LUV-P01) and playback. 4.Confirm that oscilloscope waveform is clear and check if RF signal level is correct or not.
