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:

RESISTOR1. 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 : Solid W : CementS : Oxide Film T : SpecialN : Metal Coating

CAPACITOR1. 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

CAUTION:This circuit diagram is original one, therefore there may be a slight difference from yours.
