CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. 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. RCD-W500C 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 PUBLISHED BY SONY. ATTENTION AU COMPOSANT AYANT RAPPORT LA SCURIT! LES COMPOSANTS IDENTIFS 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 PISES SONY DONT LES NUMROS SONT DONNS DANS CE MANUEL OU DANS LES SUPPMENTS PUBLIS PAR SONY. 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 microamperes). 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.

ELECTRICAL PARTS LIST 102 Unleaded solder Boards 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 40C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350C. 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 bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. RadioFans.CN 收音机爱 好者资料库 4 RCD-W500C SECTION 1 SERVICING NOTE 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. 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. Message C12/ Cannot Copy C13/ Rec Error C14/ TOC Error C41/ Cannot Copy C71/ Din Unlock Explanation You are trying to record a disc that cannot be played back in DECK-A or with an external device, such as CD-ROM or VIDEO CD. Remove the disc, and then insert a music CD for playback. Recording has not been completed successfully because of vibration. Relocate the unit in a place free of vibration and restart the recording again. The disc you try to record is excessively dirty (such as oil- stained or finger marked) or scratched. Or the disc is not normal. Replace the disc with another one and restart the recording again. The unit did not read the TOC information. Insert other discs. The sound source you are trying to record is a copy of a commercial music software. Or you are trying to record on a CD-R/CD-RW digitally. Because of the restriction of the Serial Copy Management System, you cannot record a copy of a commercial music software. Neither can you record a CD-R/ CD-RW digitally. If this message is displayed momentarily, this is not an error. It is caused by the digital signal during recording. During recording of a digital sound source, the connecting cable has been disconnected or the player of the sound source has turned off. Connect the cable or turn on the digital player. Self-diagnosis Function When the self-diagnosis function is activated to prevent the player from malfunctioning, three character service numbers in a combination with a message appears in the display. In this case, check the following table. 5 RCD-W500C SECTION 2 GENERAL 36 4 1 1 POWER button 2 H button 3 DISC 1 to DISC 5 A button and indicators 4 CD SYNCHRO NORMAL button 5 CD SYNCHRO HIGH button 6 OPEN/CLOSE button 7 H button 8 INPUT button 9 FINALIZE button q; ERASE button qa SBM button and indicator qs REC z button qd X button qf REC LEVEL knob qg x button qh PLAY MODE button qj TIME button qk DISPLAY button ql YES button w; l AMS L knob wa CLEAR button ws MENU/NO button wd l AMS L knob wf ALBUM button wg PLAY MODE button wh TIME button wj x button wk PHONES jack wl X button e; PHONE LEVEL knob 2 5 978q; qa qs qd qfqgqhqjqkqlw;wdwawfwjwk e; wl wgwhws 6 RCD-W500C SECTION 3 DISASSEMBLY Note : Disassemble the unit in the order as shown below.
