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. Flexible Circuit Board Repairing · Keep the temperature of soldering iron around 270°C 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 damaged by heat. 2 SECTION 1 DIAGRAMS 1-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS Note on Printed Wiring Board: · X : parts extracted from the component side. · b : Pattern from the side which enables seeing. · Indication of transistor.
