SPECIFIED ONES FOR MAINTAINING 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

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

Ω

/V tester.

2. 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.
The waveform test point is indicated with the mark
(

) in the wiring diagram.
