Note:
• All capacitors are in µF unless otherwise noted. pF: µµF 50WV
or less are not indicated except for electrolytics.
• Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4W
• All resistors are in ohms. (1M: 1000kΩ, 1k: 1000Ω)
• : nonflammable resistor.
• Chip resister are 1/10W unless otherwise noted.
• : fusible resistor.
• ¢ : internal component.

• : panel designation and adjustment repair.
• All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.
• METAL CHIP (:RN, :RN-CP) resister in 1%, 0.5%, 1/4W un-
less otherwise specified.
• The components identified by in this basic schematic dia-
gram have been carefully factory-selected for each set in or-
der 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 nec-
essary adjustments indicated, If results do not meet the speci-
fied value change the component identified by
3
the adjustment until the specified value is achieved. (Refer to
page 4-1 and 4-2.)
• All voltages are in V.
• Reading are taken with Component color-bar signal (R.G.B
SYNC) input.
• Voltage are dc with respect to ground unless otherwise noted.
• no mark : 14G1/14G5 series and comon
( ) : 20G1 series
• Voltage variation may be noted due to normal production
tolerancd.
• : B+, B– line
• : signal path
• Circled numbers are waveforms reference.
