This monitor will appear to be
non-functional if there is no video input signal. In order for this monitor to
operate properly, there must be a video input signal.
The monitor is equipped
with VESA DDC2B capabilities according to the VESA DDC STANDARD. It allows the
monitor to inform the host system of its identity and, depending on the level
of DDC used, communicate additional information about its display capabilities.
This LCD TV l contain a main board (include audio), a switching
power board, a function keyboard, an IR Board and a side board. The main board
and power board will house the flat panel to control logic I2C bus, DDC,
brightness control logic for LCD panel, DC-DC conversion to supply the
appropriate power to the whole board and transmitting TTL level signals into
LCD Module to drive the LCD display circuit.
The inverter board will drive the five CCFLs (Cold Cathode Fluorescent
Lamp).
The switching power board will provides the power ON/OFF to control the TV and control LED indicator for DPMS. The function keyboard and Remote Control will provide the OSD control signal to the Main Board.

The following symptoms are normal with LCD TV monitor and do not
indicate a problem.
> Due to the nature of the fluorescent light, the screen may flicker
during initial use. Turn off the Power Switch and then turn it on again to make
sure the flicker disappears.
> You may find slightly uneven brightness on the screen depending on the desktop pattern you use.
> The LCD TV screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such as a missing pixel or a pixel lit all of the time.
> Due to the nature of the LCD TV screen, an afterimage of the previous screen may remain after switching the image, when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image or turning off the Power Switch for hours.
