1. Electrical Assembly Alignment
1.1. Preconditions – 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 error should destroy the board. For example,the output
of DC/DC and LDO should not 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(AVDD3V3, DVDD3V3, VCCK,etc.), the voltage for DDR (DDRV) , the
voltage for amplifier(AUDIO_PWR),etc. Only the standby voltage is necessary if there is no
software in the flash .
1.2. SW download
Download the latest release MT8223_SW into the flash using MTK SW tool. See Appendixo
“How to download FLASH SW”. Or upgrade the SW from USB port See Appendixp” How to
upgrade FLASH SW from USB”.
1.3.Panel ID check and modify
There is different ID stored in the NVM depended on different Panels. Modify it with Hyper
terminal if the initial ID or a wrong ID make the set can not display clearly. See Appendixr. It can
be checked and modified in Factory menu->Feature->Panel ID if the set can display clearly .
The set should be restart if the panel ID is changed .
1.4.Functional Test
Once the boards (chassis, KB, IR, PSU…) and the panel are well interconnected, connect all
external generator devices to relevant inputs/outputs below according to their respective test
patterns format and check picture content and sound quality accordingly:
Source Test signal (generator) Test pattern (format/image)
Analog Tuner RF cable Full Band (VHF/UHF) + CATV
Composite(CVBS) Chroma/Fluke PAL Half Color & Gray bars
VGA Chroma/QuantumData 1024x768@60Hz
Half Color & Gray bars
CMP (YPrPb) Chroma/QuantumData 1080i@60Hz
Half Color & Gray bars
HDMI DVD with HDMI compliancy Movie 720p@60Hz
Headphone RF cable First channel
Loud Speakers RF cable First channel
Audio tones can be defined by the factory (ie: 1KHz & 3KHz, sweep, …).
Picture video formats can be changed by the factory according to their own standard.
1.5. ADC Calibration
To ensure the ADC performance, the error of “generator+cable” must be less than 2%. The

Factory Alignment Specification of normal SIACP
Page 5 of 10
following inputs require an ADC calibration for the time being.
