5-2. PRINTED WIRING BOARDS AND
SCHEMATIC DIAGRA MS
• All capacitors are in µF unless otherwise noted. pF : µµF 50V or less
are not indicated except for electrolytics and tantalums.
• All electrolytics are in 50V unless otherwise specifi ed.
• Indication of resistance, which does not have one for rating electrical
power, is as follows:
Pitch : 5mm
Rating electrical power : 1/ 4 W (CHIP: 1/10W)
• All resistor are in ohms.
KW = 1000W MW = 1000KW
•
: nonfl ammable resistor.
•
: fusible resistor.
•
: internal component.
•
: panel designation and adjustment for repair.
•
: earth ground
•
: earth-chassis
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• The components identifi ed by
X 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
necessary, replace only with the value originally used.
• When replacing components identifi ed by
Y, make the necessary
adjustments as indicated. If the results do not meet the specifi ed
value, change the component identifi ed by
X and repeat the
adjustment until the specifi ed value is achieved (Refer to Safety
Related Adjustment on Page 14).
5-1. CIRCUIT BOARDS LOCATION
The components identifi ed by shading and ! symbol are critical for safety. Replace
only with part number specifi ed.
The symbol
indicates a fast operating fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.
Les composants identifi es per un trame et une marque
! sont critiques pour la
securite. Ne les remplacer que par une piece portant le numero specifi e.
Le symbole
indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
• When replacing the parts listed in the table below, it is important to
perform the related adjustments.

• All voltages are in V.
• Voltages are DC with respect to ground unless otherwise noted.
• Readings are taken with a 10MW digital multimeter.
• Readings are taken with a color-bar signal input.
• Circled numbers are waveform references.
