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 k

Ω

/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.
