Test and Alignment Specification for RT2841 Series (v0.01).docx
Page 5 of 27
INFO:
All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage (
220 ~ 240 VAC
)
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
25+/-7°C
The Picture Performance assessment such as Gamma Correction and White Balance (luminance and
colortemperature) has to be performed into subdued lighted room after at least
45min
of warm-up in order to avoid any
temperature drift influence (colorimetric vs. time)

1.1.
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 specification.
For example, check SoC voltage(AVDD3V3,DVDD3V3,VCCK_1V0,AVDD1V0_STB,095VM,3V3SB, etc.), DDR
voltage (DDRV_1V5,1V5M) , audio amplifier voltage(24V AMP_VCC),etc...
Measurements should fulfill specification within ±5% tolerances.
Note
①:
See enclosed circuit diagram for more details.
