DESCRIPTION OF SCHEMATIC DIAGRAM

VOLTAGE MEASUREMENT CONDITION:
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 kΩ/V tester.
WAVEFORM MEASUREMENT CONDITION:
1. 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.
2. indicates waveform check points (See chart,
waveforms are measured from point indicated to
chassis ground.)
INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1. The unit of resistance "Ω" is omitted.
(K=kΩ=1000 Ω, M=MΩ).
2. All resistors are ± 5%, unless otherwise noted.
(J= ± 5%, F= ± 1%, D= ± 0.5%)
3. All resistors are Carbon type, unless otherwise noted.

CAPACITOR
1. All capacitors are mF, unless otherwise noted.
(P=pF=mmF).
2. All capacitors are Ceramic type, unless otherwise
noted.
