CHAPTER 9. 
SCHEMATIC DIAGRAM
[1] DESCRIPTION OF SCHEMATIC DIAGRAM
1. VOLTAGE MEASUREMENT CONDITION:
1. Voltages at test points are measured at the supply voltage of AC 220V. Signals are fed by a color bar signal generator for servicing purpose and the above
voltages are measured with a 20k ohm/V tester.
2. WAVEFORM MEASUREMENT CONDITION:
1. Waveforms at test points are observed at the supply voltage of AC 220V. Signals are fed by a color bar signal generator for servicing purpose.
3. INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1. he unit of resistance “
Ω” is omitted.
  (K=k
Ω=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 REPLACING 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.
