OSD R/G/B

1. The voltages at test points are measured on

exclusive AC adaptor and the stable supply voltage
of AC 120V.  Signals are fed by a color bar signal
generator for servicing purpose and the above
voltages are measured with a 20k ohm/V tester.

RESISTOR
1. The unit of resistance “

Ω

” is omitted.

(K=k

).

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.
