7. Video Circuit

7.1 Video Pre-amplifier

The U201 is a video pre-amplifier. It is used to control the following functions.

(Fig. 7.1) Video Pre-amplifier

7.1.1 Video Signal Mixing

In U201, the video signal is mixed with the OSD signal (3, 2, 1 for B, G, R respectively). Then, the resultant
signal is mixed with the horizontal blanking waveform signal. Outputs for B, G, R are generated from Pins 18,
19, and 20, respectively.

7.1.2 Video Clamp

The clamp waveform signal with a polarity is output from the oscillator IC (U501) and is input to U201 Pin 23.

7.1.3 Horizontal Blanking

The collector pulses of Q314 are divided by the combination of C331 and C332. The obtained pulses are
used as the horizontal blanking pulses and is input to U201 pin 24 with a positive polarity. The potential at
Pin 24 is HIGH during the horizontal flyback period and the video output voltage of U201 is dropped to
perform the blanking operation.
