COMPONENTS IDENTIFIED 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 PUBLISHED BY SONY. ATTENTION AU COMPOSANT AYANT RAPPORT LA SCURIT! LES COMPOSANTS IDENTIFIS PAR UNE MARQUE 0 SUR LES DIAGRAMMES SCHMATIQUES ET LA LISTE DES PICES SONT CRITIQUES POUR LA SCURIT DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PICES SONY DONT LES NUMROS SONT DONNS DANS CE MANUEL OU DANS LES SUPPLMENTS PUBLIS PAR SONY. SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE The AC leakage from any exposed metal part to earth Ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of three methods. 1.A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. 2.A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3.Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A) Fig. A.

LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output three times. 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. Flexible Circuit Board Repairing Keep the temperature of soldering iron around 270C 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. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. SECTION 1 SERVICING NOTES (1) NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic 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 repain 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 pick- up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. The emission check enables continuous checking of the S curve. When the bottom plate is removed, the RF board can be checked. eleven screws (BVTP3 8) RF board bottom plate 4 SCD-C555ES SECTION 2 GENERALThis section is extracted from instruction manual. 9 EX-CHANGE button (18) Press to replace discs while playing a disc. 0 CHECK button (23) Press to check the programmed order. qa lAMSL dial (AMS: Automatic Music Sensor) (7, 14) When you turn the lAMSL dial counterclockwise by one click, you go back to the preceding track; when you turn the lAMSL dial clockwise by one click, you go to the succeeding track. qs CLEAR button (23) Press to delete a programmed track number. qd DISC SKIP button (14) Press to select the disc. qf PHONES LEVEL control Adjust the headphones volume. qg PHONES jack Connect the headphones.
