DESCRIPTION OF

SCHEMATIC DIAGRAM

VOLTAGE MEASUREMENT CONDITION:

1. Voltages at test points are measured at the

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.

WAVEFORM MEASUREMENT CONDI-

TION:

1. Waveforms at test points are observed at the supply

voltage of AC 120V. Signals are fed by a color bar

signal generator for servicing purpose.

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 1/10W, 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

CAUTION:

This circuit diagram is original one, therefore there may be a

slight difference from yours.

SAFETY NOTES:

1. DISCONNECT THE AC PLUG FROM THE AC

OUTLET BEFORE REPLACEING PARTS.

2. SEMICONDUCTOR HEAT SINKS SHOULD BE

REGARDED AS POTENTIAL SHOCK HAZARDS

WHEN THE CHASSIS IS OPERATING.

IMPORTANT SAFETY NOTICE:

PARTS MARKED WITH “

”

( ) ARE

IMPORTANT FOR MAINTAINING THE SAFETY OF

THE SET. BE SURE TO REPLACE THESE PARTS

WITH SPECIFIED ONES FOR MAINTAINING THE

SAFETY AND PERFORMANCE OF THE SET.
