According to the requirement of order, we suggest take the below steps to finish the appropriate settings.
Note:
All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage
( )
All voltages have to be measured with respect to ground, unless otherwise stated
All final tests have to be done on a complete set including LCD panel in a room with temperature of

The Picture Performance assessment such as White Balance (luminance and colour temperature)
has to be performed into subdued lighted room after at least of warm-up in order to avoid any
temperature drift influence (colorimetry vs time).

Before power-on, please check the board according to the relevant block diagram and circuit diagram,
make sure that no serious issue or mistake can destroy the board. For example, the output of DC/DC and
LDO should not be shorted to ground.
Supply a suited voltage and power-on, then check the voltage according to the relevant block diagram,
circuit diagram and voltage spec, the error should be less than 5%, for example, the voltage for main chip
(+3V3, +2.5V, VDDC1V15, 1V5_DDR, etc.), the voltage for TUNER (TU_3V3), the voltage for amplifier
(AMP_VCC), etc.
