6-4. PRINTED WRING BOARDS AND SCHEMATIC DIAGRAMS

•All capacitors are in μF unless otherwise noted. pF : μμF 50WV or less are not indicated except for electrolytics and tantalums.

•All electrolytics are in 50V unless otherwise specified.

•All resistors are in ohms. KΩ=1000Ω, MΩ=1000kΩ

•Indication of resistance, which does not have one for rating electrical power, is

as follows.

•1/ 4 W in resistance, 1/10 W and 1/ 8 W in chip resistance.

• : nonflammable resistor.

• : fusible resistor.

• : internal component.

• : panel designation and adjustment for repair.

•All variable and adjustable resistors have characteristic curve B, unless other- wise noted.

•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 adjust- ments indicated. If results do not meet the specified value, change the compo-

nent identified by and repeat the adjustment until the specified value is achieved. (Refer to R530 and R531 adjustment on Page 15.)

•When replacing the part in below table, be sure to perform the related adjust- ment.

•Readings are taken with a color-bar signal input.

•Readings are taken with a 10MΩ digital multimeter.

•Voltages are DC with respect to ground unless otherwise noted.

•Voltage variations may be noted due to normal production tolerances.

•All voltages are in V.

S : Measurement impossibillity.

•: B+line.

• v : B-line.

(Actual measured value may be different).

• : signal path. (RF)

•Circled numbers are waveform references.

The symbol display is on the component side.

The components identified by shading and mark are critical for safety. Replace only with part number specified.

The symbol indicate fast operating fuse. Replace only with fuse of same rating as marked.

Les composants identifiés per un tramé et une marque sont critiques pour la sécurité. Ne les remplacer que par une

piéce portant le numéro spécifié.

Le symbole indique une fusible a action rapide. Doit etre remplacee par une fusible de meme yaleur, comme maque.
