IC100, IC-SMD MSD3819TX-UQY LFBGA TRAY Main IC:
Main integrated circuit IC100's specifications: Digital (DVB-T/C) and analog
broadcasting demodulator, USB recording, Broadcast and A/V d(NTSC/PAL/SECAM)
Full HD 100Hz support, MPEG-2 and MPEG-4 support, 32-Bit Linux based processor,
Sound and subwoofer processor and interface, 2 USB, 4 HDMI, 2 DDR3 RAM.
Main integrated circuit collects and processes data coming from all inputs and sends
audio and video output to the speaker over amplifier and to the panel over LVDS line.
This integrated circuit has more than 500 legs. Special equipment is required for
installation and removal. Therefore, these integrated circuits are designed with very
low error ratios. If you suspect any error with main IC on TV, firstly supplies of this
IC should be checked. There are 4 input supplies as 3.3V, 2.5V, 1.05V and 1.5V.
Extremely low or high ratings of these supplies might cause image freezing, some
