Ð 3 Ð S801 CHUCK PLATE JIG ON REPAIRING On repairing CD section, playing a disc without the lid (CD), use Chuck Plate Jig. ¥ Code number of Chuck Plate Jig: X-4918-255-1 SECTION 1 SERVICING NOTES LASER DIODE AND FOCUS SEARCH OPERATION CHECK 1. Turn POWER switch on with to disc inserted and press FUNCTION button to CD position. 2. Open the lid (CD). 3. Turn on S801 as following figure. 4. Press the ( (CD) button. 5. Confirm the laser diode emission while observing the objecting lens. When there is no emission, Auto Power Control circuit or Optical Pick-up is broken. Objective lens moves up and down three times for focus search. HOW TO CHANGE THE FM CERAMIC FILTERS This model is used three ceramic filters of CF1, 2 and CF3. Therefore, the ceramic filters must change three pieces together since itÕs supply three pieces in one package as a spare parts. SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK ! 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. CAUTION Use of controls or adjustments or performance of proce- dures other than those specified herein may result in haz- ardous radiation exposure. Flexible Circuit Board Repairing ·Keep the temperature of the soldering iron around 270ûC 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. 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. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown 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 emission, observe from more than 30 cm away from the objective lens. ATTENTION AU COMPOSANT AYANT RAPPORT Ë LA SƒCURITƒ!! LES COMPOSANTS IDENTIFIƒS PAR UNE MARQUE ! SUR LES DIAGRAMMES SCHƒMATIQUES ET LA LISTE DES PIéCES SONT CRITIQUES POUR LA SƒCURITƒ DE FONCTIONNEMENT.
