1-4. Waveform and Voltage Measurement

• The various wave forms of the color circuit and
voltage measurement values are for when the service
color bar signal is received with ample reception and a
proper image is received.
• Other various wave forms of circuits and voltage
measurement values are for when general broadcasts
are normally received and will differ slightly depend-
ing on the broadcast contents. Use it as a standard
during servicing.
• All voltage values except the waveforms are expressed
in DC and measured by a digital voltmeter.

1-5. Precautions for Part Replacement

• In the schematic diagram, parts marked
F800) are critical part to meet the safety regulations,
so always use the parts bearing specified part codes
(SN) when replacing them.
• Using the parts other than those specified shall violate
the regulations, and may cause troubles such as
2-1 operation failures, fire etc.
