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
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.
2. indicates waveform check points (See chart, waveforms are
measured from point indicated to chassis ground.)
INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
