ELECTRICAL PARTS LIST ............................... 46 ATTENTION AU COMPOSANT AYANT RAPPORT Ã- LA SÉCURITÉ! LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COM- POSANTS QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.SAFETY-RELATED COMPONENT WARNING!! 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 PUB- LISHED BY SONY. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure. SAFETY CHECK-OUT After correcting the original service problem, perform the follow- ing safety check 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 TEST 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 indica- tion is 0.75 V, so analog meters must have an accurate low- voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex- amples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suit- able. (See Fig. A) Fig. A. Using an AC voltmeter to check AC leakage. 1.5 k -„¦ 0.15 µF AC voltmeter (0.75 V) To Exposed Metal Parts on Set Earth Ground 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 ËšC 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. This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the top exterior.

-“ 3 -“ SECTION 1 SERVICING NOTES CF3 CF1 mark Mark Center frequency red 10.70 MHz blue 10.67 MHz orange 10.73 MHz black 10.64 MHz white 10.76 MHz HOW TO CHANGED THE CERAMIC FILTERS This model is used two ceramic filters of CF1 and CF3. You must used same type of color marked ceramic filters in order to meet same specifications. Therefore, the ceramic filter must changed two pieces together since its supply two pieces in one package as a spare parts. MODEL IDENTIFICATION -“ Top View -“  MODEL NO. ICF-CD513 US, Canadian models: AC: 120 V 60 Hz 15 W AEP model: AC: 220 -“ 230 V 50 Hz 15 W The laser diode in the optical pick-up block may suffer 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 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 emis- sion, observe from more than 30 cm away from the objective lens.NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNITDISC REMOVAL PROCEDURE (at POWER OFF) 1) Remove the cabinet (upper). (Refer to page 6 CABINET (UP- PER)) 2) Remove the front assy, cabinet. (Refer to page 6 CABI- NET FRONT ASSY) 3) Remove the CD mechanism deck. (Refer to page 7 CD MECHANISM DECK (KSL-213BGN) 4) Turn the gear (C) in the direction of the arrow. 5) When the gear (P) reaches the position shown in the figure, rotate it towards the arrow (A) position. 6) Pull out the disc table once it comes out a little. 1 gear (C) 2 gear (P) 3 A
