SCHEMATIC DIAGRAMS
Description:
VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on exclusive AC adaptor and the stable supply voltage of AC 230V.
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 & CAPACITOR:
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.
C

CAPACITOR
1. All capacitors are µF, unless otherwise noted. (P=pF=µµ F).
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
