SCHEMATIC DIAGRAMS
Description:
VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on 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 “
:
” is omitted. (K=k
:
=1000
:
, M=M
:
).
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.

CAPACITOR
1. All capacitors are
F, unless otherwise noted. (P=pF=
F).
2. All capacitors are 50V, unless otherwise noted.
3. All capacitors are Ceramic type, unless otherwise noted.
