These chassises are designed for European LCD TV with MPEG4. The
main chip is from Mediatec (MT5362 series) and supports below inputs and
outputs.
Factory Alignment Specification of
normal SIACP
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(DV33, AV33,DV18,DV11,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.

SW
download
Download
the latest release MT62_SW into the flash using MTK SW tool. See Appendixo “How
to download FLASH SW”. Or upgrade the SW from USB port if there is a initial SW
in the falsh and the set can work normally.
Download the latest release MEMC_SW (skip this
step if no MEMC module on the chassis).
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. It can be checked and modified in Factory menu-> Feature -> Panel ID if the set can display clearly .
The set will restart if the panel ID is changed.

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.

ADC Calibration
To ensure the ADC performance, the error of “generator + cable” must be less than 2%. The following inputs require an ADC calibration for the time being.
ƒ VGA(skip this step if no VGA input on the chassis)
Provide a test signal 1024×768@60Hz with WhiteBlack squares.
Select the corresponding FactoryMenu > ADC Calibration > Auto Color , then press ”OK” key on Remote Control to start. Value of status will change to “OK” if succeed.
ƒ CMP
Provide a test signal 720p@60Hz with 100% 8 steps ColorBar.
Select the corresponding FactoryMenu -> ADC Calibration -> Auto Color , then press ”OK” key on RemoteControl to start. Value of status will change to “OK” if succeed.
ƒ Scart RGB
Provide a test signal PAL 576i with 100% 8 steps ColorBar.
Select the corresponding FactoryMenu -> ADC Calibration -> Auto Color , then press ”OK” key on RemoteControl to start. Value of status will change to “OK” if succeed.
The mean of status value:
“NONE”= no input is successful in ADC calibration.
“OK”= current input is successful in ADC calibration.
“NOK”= current input is fail in ADC calibration.
“ALL”= all inputs required are successful in ADC calibration.
R Gain, G Gain, B Gain, R Offset, G Offset, B Offset in FactoryMenu -> ADC Calibration page can be fine-tuned if necessary but not required.
DDC &
EDID Test
The E-EDID data structure are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for HDMI).
Both VGA and HDMI have their own separate bin files:
For EDID check, it’s needed to check whether the correct EDID is downloaded by checking corresponding EDID NVM Checksum or read them out to check bit by bit if it is in line with the
released EDID bin file.

HDCP Test
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set CI+ Key activation and test(This step is only for the models with CI+ function )
Select factory menu -> Update CI+ Credential -> Update CI+ Credential , then press ”OK” key on Remote Control to active the CI+ KEY. The Valid(CI+ state) state turn to “Yes” and Cus Code(Custom Code), Serial Num display if succeed. Download the CI+ Key and try to active it again if fail.

Press Remote Control key “Blue” To pop-up the Factory Menu in case of “Factory Key” is enable.
The status of “Factory Key” can be changed in FactoryMenu -> System -> FactoryKey
Press Remote Control “OK” key or “RIGHT” key to enter the sub-menu.
Press Remote Control “Menu” key to go back to the root menu.
Press Remote Control “RIGHT” or “LEFT” key to change the values.

White Balance
Alignment
Make sure that the picture mode is “vivid”, enter to “P” mode(turned on the factory key) and switch off “Pic. Enhance” in Factory Menu-> WD Alignment before white balance alignment.
VGA,CMP,SCART RGB,DTV,CVBS_PAL Color Coordinates are relative to HDMI.
CVBS_SECAM and CVBS_NTSC Color Coordinates are relative to CVBS_PAL.
Warm and Cool Color Coordinates are relatives to Normal mode.
Only HDMI(YUV 720p@60Hz) input requires color temperature adjustment. All the Relative Matrix Offsets should be set while doing alignment.

Expected Targets and Tolerances
The measured parameters should be “x, y” coordinates.
The White Balance alignment should be performed using a contact less analyzer (ei: Minolta CA-210). The analyzer may not touch the screen surface, and measurement must be performed in a dark environment keeping the probe(s) at 90+/-2° from the panel.
The result should measure up the relevant spec.
