OVERVIEW
FA - GENERAL
1-2
The IC6000 is the 8 bits & 80K microcontroller and the
IC6001, 221-00745-05, is the EAROM memory. The
IC6000 handles the communication thru IIC BUS, I/O
ports, ADC converters for the keyboard, also supplies the
OSD signals for the On screen menus and the Close Cap-
tion decoding.
The main board is using three main linear regulators for
providing several voltage sources, the ICX3821 [5VSW]
for Tuner and IC2200 , ICX3820 [5VSB] for the IC6000/
1 and ICX3822 [9VSW] for most of the rest of IC’s. The
VSW stand for SWITCHED VOLTAGE, these regulators con-
tain an internal power switch to turn them on/off, from
a Power Control signal provided by the IC6000.
Finally the main board has a provision for an additional
IC, for switching the YUV inputs. The objective of this
IC2902 is for adding an extra YUV input. This circuit
will be available for a future model.
On the large signal module there are five IC’s , the ICX3612
is the main power switching and PWM hybrid circuit and
in conjunction with ICX3702 made the main power regu-
lation of this chassis. The purpose of this regulator is to
provide a proper protection for avoiding to shut the
main power supply off and therefore the complete TV set.
And of course, avoid the necessity of fuse replacement
due to a short circuit on the third party TV card.
The ICX2100 is the Vertical output amplifier and is pro-
cessing the small signal provided by the IC2200 on the
small signal board. Also the IC3300 is processing the
EAST/WEST correction for the screen geometry.
Finally The IC5100 is used to amplify the RGB small sig-
nals from the IC2200 and then display them on the CRT
cathodes.
