DESCRIPTION OF SCHEMATIC DIAGRAM
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH "
INPORTANT FOR MAINTAINING THE SAFETY OF
THE SET.
BE SURE TO REPLACE THESE PARTS WITH
SPECIFIED ONES FORMAINTAINING THE SAFETY
AND PERFORMANCE OF THE SET.
CAUTION:
This circuit diagram is original one, therefore there
may be a slight difference from yours.
1. When the exclusive-use AC adapter is used, the color
bar signal of color bar generator for service is input
to get the normal screen. When the audio is
minimized, the voltage value is measured with the
20 kΩ/V tester.
2. When the exclusive-use AC adapter is used, the color
density, lightness and color hue are set to the center
position, and the signal of color bar generator for
service is observed to get waveform.
The wave form test point is indicated with the mark
(
) in the wiring diagram.
