CIRCUIT BOARDS LOCATION • All voltages are in V. • Readings are taken with a 10 M digital multimeter. • Readings are taken with a color-bar signal input. • Voltage variations may be noted due to normal production tolerances. * • : Can not be measured. • Circled numbers are waveform references. • s : B + bus. • S : B - bus. A D H Note: The components identified by shading and mark ! are critical for safety. Replace only with part number specified. 5-3. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS Note: Les composants identifiés per un tramé et une marque ! sont critiques pour la sécurité. Ne les remplacer que par une pièce portant le numéro spécifié. Note: • All capacitors are in µF unless otherwise noted. (pF: µµF) Capacitors without voltage indication are all 50 V. • Indication of resistance, which does not have one for rating electrical power, is as follows. Pitch: 5 mm Rating electrical power 1/4 W (CHIP : 1/10 W) • All resistors are in ohms. f • : nonflammable resistor. Ï • : fusible resistor. • ¢ : internal component. p • : panel designation, and adjustment for repair. • All variable and adjustable resistors have characteristic curve B, unless otherwise noted. •e : earth-ground. •E : earth-chassis. • The components identified by [ in this basic schematic diagram have been carefully factory-selected for each set in order to satisfy regulations regarding X-ray radiation. Should replacement be required, replace only with the value originally used. • When replacing components identified by ], make the necessary adjustments indicated. (See page 3-1) • When replacing the part in below table, be sure to perform the related adjustment.
