Video/Audio Signal Process - 5
The main function of the A board is to select and process one of the incoming video signals.
IC8601 is just switches of USB signals. The built in WiFi module is connected by USB type
terminal.
Video input, Component Video Input, HDMI input and the composite video output of the tuner
are all connected to IC8000 for selection. The video input signal can be two formats: Video, or Y,
Pb, Pr. A comb filter inside IC8000 converts the composite video signal of the main picture to Y
and C (luminance and chrominance) signals. The signal is then converted to RGB. At the
completion of this process, the format of the composite signal is now the same as a digital 1080i
component signal. If the incoming video is in the 480p, 720p, 1080i, and 1080p format, the Y, Pb,
and Pr signals undergo A/D (analog to digital) conversion. Finally all picture signals are
converted to 1080p.
Digital television reception of the tuner is output in the form of an IF (Intermediate Frequency)
signal. The transport stream from the tuner enters the VSB I/F (Interface) section of IC8000 where
the video signal is extracted and converted to YUV data. The output is provided to the Video Input
I/F for selection. The JPEG data of the SD card enters the JPEG I/F section of IC8000 for
conversion into YUV data and output to the Video Input I/F circuit. The video input interface
outputs the selected picture data to the video process circuit.
This Video Process section of the IC performs all picture control operations such as brightness,
contrast, color, tint, etc. On Screen Display data such as channel numbers, Digital TV closed
caption, and picture adjustments are mixed with the video data. If in 3D mode, it converts to the
right and left pictures. After the process, LVDS (Low Voltage Differential Signaling) is output to
LCD panel module. # IC9000 is the frame rate converting IC for high speed LCD panel. IC4300
adjust the brightness for HDR feature.

Troubleshoot for Video Signal Problem
:When abnormal picture is displayed, troubleshoot by the test pattern in LCD module.
If the picture is no problem, A board must be defective.
If the picture is also abnormal, LCD panel module must be defective. Just in
case, confirm the flat cable connection between A board and T-CON board.
How to enter :
While pressing "volume(-)" button of the TV unit, Some patterns are
press "option/yellow" button of the remote control 3 times within 2 seconds. automatically changed.
How to exit : The patterns are depend
on the LCD panel.
Switch off the TV unit
#)The test pattern is created by the circuit in LCD Panel Module(T-CON board).

Troubleshoot for Video/Audio Signal Problem
: Customers also can check the picture and sound by internal data.
If the picture and sound is no problem, the reason of trouble is mostly not a TV.
How to display :
