Note :
• All capacitors are in µF unless otherwise noted.
• pF : µµF 50WV or less are not indicated except for
electrolytic types.
• Indication of resistance, which does not have one for
rating electrical power, is as follows.
Pitch : 5mm
Electrical power rating : 1/4W
• Chip resistors are 1/10W
• All resistors are in ohms.
k = 1000 ohms, M = 1000,000 ohms
• : nonflammable resistor.
• : fusible resistor.
• : internal component.
• : panel designation or adjustment for repair.
• All variable and adjustable resistors have
characteristic curve B, unless otherwise noted.
• All voltages are in Volts.
• Readings are taken with a 10Mohm digital mutimeter.
• Readings are taken with a color bar input signal.
• Voltage variations may be noted due to normal production
tolerences.
• : B + bus.
• : B - bus.
• : RF signal path.
• : earth - ground.
• : earth - chassis.

Note : The components identified by shading
and marked are critical for safety.
Replace only with the part numbers
specified in the parts list.

confidential information.
Strictly follow the instructions whenever
the components are repaired and/or
replaced.
Note :
• CVBS and RGB waveforms are measured using a PAL colour bar
input to Scart1. Y, U, V waveforms are measured using a PAL colour
bar input to component sockets (Y, Pb/Cb, Pr/Cr).
