Factory Alignment Specification of normal SIACP

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 White Balance (color temperature) has to be performed into subdued lighted room after at

least 1 hour of warm-up/burn-in. This is applicable for both Alignment and Picture Performance

evaluation at OQA in order to be set free of any temperature drift ( colorimetry vs time)

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(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

1.2.

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

See Appendixp” How to upgrade FLASH SW from USB”.

Download the latest release MEMC_SW (skip this step if no MEMC module on the chassis).

See Appendixs “How to download FLASH SW for MEMC module”.

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

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

following inputs require an ADC calibration for the time being.

 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->

key on

RemoteControl to start. Value of status will change to “OK” if succeed.

ADC Calibration-> Auto Color , then press ”OK”

 CMP

Provide a test signal 720p@60Hz with 100% 8 steps ColorBar.

Select the corresponding Factor yMenu->

key on

RemoteControl to start. Value of status will change to “OK” if succeed.

 Scart RGB

Provide a test signal PAL 576i with 100% 8 steps ColorBar.

Select the corresponding FactoryMenu->

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.

ADC Calibration-> Auto Color , then press ”OK”

ADC Calibration-> Auto Color , then press ”OK”

1.6. 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.

1.7. HDCP Test

For HDCP compliancy, it’s needed to check whether the HDCP key has been well set.

1.8. 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

RemoteControl to active the CI+ KEY. The Valid(CI+ state) state turn to “Yes” and Cus

on

Code(Custom Code), Serial Num display if succeed. Download the CI+ Key and try to active it

again if fail.

2. Final Assembly Alignment

2.1. FactoryMenu

Follow the below steps to pop-up the Factory Menu in case of “FactoryKey” is disable

-

press RemoteControl key “MENU” to display main menu

:

- Select “Picture” and press “OK” key to enter the picture submenu

in “P” mode.

2.3. White Balance Alignment

Make sure that the picture mode is “vivid”, enter to “P” mode(
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.

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

turned on the factory key) and

All the Relative
