6-5. PRINTED WIRING 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.

K =1000 , M =1000k

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

as follows.

Pitch : 5mm

Rating electrical power :

•

W in resistance,

W and

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 20.)

• 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 10M 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 impossibility.

•

: B+line.

•

: 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

indicates a fast operating fuse.

Replace only with fuse of same rating as marked.

G/GA

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.
