DESCRIPTION OF SCHEMATIC DIAGRAM
VOLTAGE MEASUREMENT CONDITION:
1. When the exclusive-use AC adapter is used, the colour
bar signal of colour bar generator for service is input to
get the normal screen. When the audio is minimized,
the voltage value is measured with the 20 k
get the normal screen. When the audio is minimized,
the voltage value is measured with the 20 k
Ω/V tester.
WAVEFORM MEASUREMENT CONDITION:
1. When the exclusive-use AC adapter is used, the colour
density, lightness and colour hue are set to the center
position, and the signal of colour bar generator for
service is observed to get waveform.
