LC-20B4M

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.

: Solid

: Cement

: Oxide Film

: Special

: Metal Coating

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.

(ML): Mylar (TA): Tantalum

(PF): Polypro Film (ST): Styrol
