SAFETY CHECK-OUTAfter correcting the original service problem, perform the following safety checks before releasing the set to the customer: 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. 2. Check the interboard wiring to ensure that no wires are pinched or contact high-wattage resistors. 3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement.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.

4. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 5. Check the B+ voltage to see it is at the values specified.

(In addition to this, the necessary note is printed in each block.)For printed wiring board: X : indicates a lead wire mounted on the component side. x : indicates a lead wire mounted on the printed side. a : Through hole. x : Parts mounted on the conductor side. b : Pattern from the side which enables seeing. (The other layers patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated. For schematic Diagram: Caution when replacing chip parts. New parts must be attached after removal of chip. Be careful not to heat the minus side of tantalum capacitor, because it is damaged by the heat. All resistors are in ohms, 1/4 W (Chip resistors : 1/10 W) unless otherwise specified. k : 1000, MW : 1000k. All capacitors are in F unless otherwise noted. pF : F 50V or less are not indicated except for electrolytics and tantalums. All variable and adjustable resistors have characteristic curve B, unless otherwise noted. 2 : nonflammable resistor. 5 : fusible resistor. C : panel designation. f : internal component. C : adjustment for repair. U : B+ Line. V : B Line. Circled numbers refer to waveforms. Voltages are dc between measurement point. Readings are taken with a color-bar signal input. Readings are taken with a digital multimeter (DC 10MW). Voltage variations may be noted due to normal production tolerances. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. When indicating parts by reference number, please include the board name.
