¢ DESCRIPTION OF SCHEMATIC DIAGRAM
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 kQ/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 colour bar generator for service is observed to get waveform.
The waveform test point is indicated with the mark (Y) in the wiring diagram.
3. Indication of resistors and capacitors
