Figure 9-41 Microprocessor
The microprocessor, 7100, located on the ACS module,
controls the Convergence, Geometry, and CRT drive circuits.
Settings for Convergence, Geometry, and White drive are
stored in the NVM, 7000. This IC is 512K for the AP sets and
256K for the Korean version. When 7100 reads the size of
7000, it then determines which software to load. If it reads 512K
present, the AP software is loaded. If it reads 256K, NTSC only
software is loaded. Commands for the ACS processor are
produced by the OTC on the SSB and transmitted via the TXD
and RXD lines.
9.5.2 Front Control Panel
Figure 9-42 Front Control Panel
The Front Control panel has the Power LED, Keyboard, IR
Receiver, and Light Sensor. The Keyboard is a resistor ladder.
The voltage changes value depending on which selection is
made. The voltage on this line will be 3.3 volts if no buttons are
selected. The two-colour LED indicates the status of the set. In
the Standby mode, the ON_OFF_LED line is High and the +9-
volt source is turned "off". In this case, the RED LED is lit.
When the set is turned "on", the +9-volt source is switched "on",
turning the Green section of the LED "on". The LED then turns
Yellow. When the set is fully "on", the ON_OFF_LED line goes
Low, turning the Red LED "off". The indicator is now Green.
The IR Receiver, 6105, receives commands from the remote
control.
9.5.3 Light Sensor
Figure 9-43 Light Sensor
The Light Sensor, 6104, is amplified by two op amps in 7000.
This circuit senses the ambient light and outputs a voltage on
pin 7 of 7000. This voltage is fed to the OTC, which makes
changes in the picture brightness to compensate for changes
in the ambient light.
