Factory Test & Alignment Specification For MS63F-LA Series (V0.10)
Page 4 of 18
INFO:
ª
All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage
(
220 ~ 240 VAC
)
ª
All voltages have to be measured with respect to ground, unless otherwise stated
ª
All final tests have to be done on a complete set including LCD panel in a room with temperature of
25+/-7°C
ª
The Picture Performance assessment such as White Balance (luminance and color temperature)
has to be performed into subdued lighted room after at least
45min
of warm-up in order to avoid any
temperature drift influence (colorimetry vs time)

Pre-Conditions and DC/DC Check
Before power-on, please check the board according to the relevant block diagram and circuit
diagram, and 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 less than 5% .For example, the voltage
for main chip(+3V3, AV3.3, +1V2, CORE1V2, etc.), the voltage for DDR (DDRV) , the voltage for
amplifier (AMP_VCC), etc...
