Service Manual

 

1) The voltages at test points are measured on exclusive AC adaptor and the stable supply voltage of AC 220-240 V. Signals are fed by a color bar signal generator for servicing purpose and the above voltages are measured with a 20k ohm/V tester.

1) The unit of resistance "

Ω" is omitted. 

(K=k

Ω=1000Ω, M=MΩ).

2) All resistors are ± 5%, unless otherwise noted. 

(K= ± 10%, F= ± 1%, D= ± 0.5%)

3) All resistors are 1/16W, unless otherwise noted. 

1) All capacitors are 

µF, unless otherwise noted.  

(P=pF=

µµF).

2) All capacitors are 50V, unless otherwise noted. 

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
