LC-20B4E

DESCRIPTION OF SCHEMATIC DIAGRAM

VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on
exclusive AC adaptor and the stable supply voltage
of AC 120V. Signals are fed by a color bar signal
generator for servicing purpose and the above
voltages are measured with a 20k ohm/V tester.
INDICATION OF RESISTOR & CAPACI-
TOR:
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 1/16W, unless otherwise noted.
4. All resistors are Carbon type, unless otherwise
noted.

CAPACITOR
1. All capacitors are µF, unless otherwise noted.
(P=pF=µµF).
2. All capacitors are 50V, unless otherwise noted.
3. All capacitors are Ceramic type, unless otherwise
noted.
