The Switched Regulator and the scan-derived
voltages from the Horizontal Output Transformer
are killed; only the Stand-By 12Vdc supply
remains active, the 24Vdc Start-Up supply is
On, but it is inactive until the Power Button is
pressed. To reset the circuit, the power cord is
removed from the 120Vac power socket,
reinserted and the Power button is pressed.
TS-10P Tuning System
The TS-10P Tuning System,
Figure 12,
is
designed exclusively for Projection TV. The
major components of this system are the
178-channel Controller, the Tuner, and the
Tuner Interface Panel. The Controller uses an
8-but Microcomputer, a CITAC IC, a Micro-
processor with internal ROM for processing On-
screen data, and a Graphics Generator/Matrix IC
to receive the On-Screen data and create the
On-Screen graphics Video signal.
The IR Remote Transmitter has 40 pushbuttons
as seen in
Figure 13.
The system performs 35
functions with the On-Set Keyboard and 64
functions with the 40-pushbutton Remote
Transmitter. The functions controlled by the 40
button Transmitter are: Power On/Off, Random
