Note:
• All capacitors are in
m
F unless otherwise noted. pF:
mm
F 50 WV or
less are not indicated except for electrolytic.
• Indication of resistance, which does not have one for rating electrical
power, is as follows.
• All resistors are in ohms.
• : nonflammable resistor.
• : fusible resistor.
• : internal component.
• : panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• : earth-ground
• : 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 by using RV904 ( ) as indicated. (See page 13)
• When replacing parts shown in the table below,
be sure to perform the safety related adjustment.
• All voltages are in volts.
• Readings are taken with a 10
MW
digital multimeter
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal production
tolerances.
• * : Cannot be measured.
• Circled numbers are waveform references.
• : B +bus.
• : B - bus.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP: 1/10 W)
Note: The components identified by shading and
mark are critical for safety. Replace only with
part number specified.
Note: Les composants identifies per un trame et une
marque
sont critiques pour la securite. Ne les
remplacer que par une piece portant le numero specifie.
