Note:
• Capacitors without voltage indication are all 50V.
• All resistors are in ohms.
kΩ=1000Ω, MΩ=1000kΩ
• Indication of resistance, which dose not have one for rating electrical power, is
as follows.
Pitch : 5mm
Rating electrical power : 1 / W

• : 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.
• : earth-chassis.
• The components identified by
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
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 RV8001, 8002, 8003 adjustment on Page 69.)
• Readings are taken with a NTSC color-bar signal input.
• Readings are taken with a 10MΩ digital multimeter.

The components identified by shading and mark
are critical for safety. Replace only with part number
specified.
The symbol
Replace only with fuse of same rating as maked.
• 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.
