Signal Circuit Overview

The K is the Remote Receiver and Power LED board. Commands that originate from the remote control or keypad of the GS board are received and processed by the system control circuit located on the A board.

The A board contains an Optical Audio Out jack for use with a Dolby Digital decoder and a multi-channel audio amplifier. When a digital channel is selected, the output from the Digital Audio Out jack is Dolby Digital. The same jack outputs PCM (Pulse Code Modulation) when any other signal source is selected.

NTSC, ATSC, and QAM television reception is performed by the A board. The unit also contains two video inputs, two HDMI inputs and two component inputs that are directly connected to the A board. The A board selects the video signal for display on the screen. It is responsible for converting all inputs into YUV data for video processing. The A board performs PIP (Picture in Picture) and picture control operations such as brightness, contrast, color, tint, etc. The PEAKS firmware of the unit also resides in this board. The RGB output of the A board passes through an LVDS (Low Voltage Differential Signaling) transmitter for conversion into serial data. The output signal is then applied to the D board.

The D board is responsible for displaying the picture. It provides the scan, sustain and data drive signals to address the panel. The scan pulses are output to the SC board. The sustain pulses are output to the SS board. The data drive signals are output to the C1, and C2 boards. The C1 board drives the right half of the panel; the C2 board drives the left half of the panel.

The SC board is responsible for the generation of the scan pulses. Scan pulses are used for initialization and selection of the pixels.

The SU and SD boards are de-multiplexer boards that are responsible for converting serial data output of the SC board into parallel data to drive the panel.

The SS board is responsible for the generation of the sustain pulses. Sustain pulses are used to initialize and control the brightness of the screen.

The SS2 and SS3 boards are extension (connector) boards used to connect the SS board to the panel.
