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
/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.
INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1. The unit of resistance
"
Ω
" is omitted.
(K=k =1000 , M=M ).
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.
(ML) : Mylar
(TA) : Tantalum
(PF) : Polypro Film (ST) : Styrol
CAUTION:
This circuit diagram is original one, therefore there may be a
slight difference from yours.
