3. DEFLECTION CIRCUIT
Vertical, horizontal drive pulses originate at M52335ASP(I501). The vertical drive pulses are connected to
Vertical Drive IC TA8445K(I301) and drive vertical deflection coils. This horizontal deflection drive pulses drive
the horizontal output circuits and deflection coils and also supply 26.5v, 180v, high voltage 25kV, focus voltage
and screen voltage by driving the FBT.
4. u-COM CIRCUITS.
Timer IC is M37267MX(I701) is made by Mitsubishi. Syscon receives the signal from the user's remocon
and it becomes serial-communication CLOCK/S DATA IN/S DATA OUT signal. Timer IC selects channel
with CLOCK /DATA /EN and receives the functions to control TV and VCR driving(OSD, VOL CTRL, TV
ON/OFF), and such functions as brightness, contrast, color, tint, sharpness, video signal, volume, caption and
program recording.
5. CHANNEL SELECTION AND MEMORY
User selects the channel, then the appropriate PLL data, clock and enable signals are sent out by the -com, to
the tuner.
The -com communicates with I702(IC24LC01B) to memorize, channel numbers, volume and video settings.
