MV (Main SW Version)
ID (Project ID)
Panel ID
MEMC (FRC SW Version)
MID(Internet info for factory)
P (Production - Factory mode flag) S (Factory UART Parser mode flag) W (Warm-Up mode flag)

How to enter Main Menu
* Press RCU “MENU” key to display main menu
* Select “Settings>Picture>Advanced setting> Contrast”, Scroll down to “Contrast” item
* Press the subsequence RCU keys “1”, “9”, “5” and “0”
* Then the Main Menu will be displayed on the screen.

Warm-up Test
Following TCL standard and practices, it’s required minimum 15min of Warm-Up that can be considered as Burn-In.
Additional Aging for White Balance alignment is no more necessary due to consistent Picture Performance with Cloning usage.
First you need to enable Factory Key. After that selecting“ Factory menu >WARM UP”, pressing RCU “OK ►” key and then leaving Factory menu by pressing “Exit” key. To release/disable Burn-in mode, it’s just required to press “Menu” button from local keyboard. Other faster methods via UART/IR commands are available on enclosed SIACP
requirements (rev. v8.31)

White Balance & Automatic Gamma correction
For the white balance & automatic gamma correction, we only need do one of them based on the value of
Align-mode in PDM system or the method gave by AOE or R&D.
The detail instruction of Align-mode is as below table:

Align mode                       WB alignment of Auto gamma correction              0 > WG alignment

                                                                                                                                  1 > Gamma correction

White Balance alignment (Golden sample)
As some color coordinates discrepancies can be noticed from panel batches to others, it may necessary to perform slight touch-up.
For Color temperature adjustment, switch TV on leading HDMI input where should be connected suitable generator providing following format 1280x720p@60Hz test pattern. A 32 steps grey scale is recommended to assess relevant colorimetry tracking and low or high light saturation points.

Ensure that TV’s picture enhance is off.
Ensure that TV is in Factory mode to access to” White Balance” adjustment submenu.
WB Normal is the first mode which is adjusted in HDMI source， the next are HDMI warm and cool mode.
Warm and Cool Tone are relatives to Normal mode. WB adjust need to fix default G Gain .Offset registers needn’t to be adjusted.
“Gain” registers set need to be adjusted at 70IRE.
Note: The operation must enable factory “P” mode
Auutomatic Gamma correction
Gamma correction, or often simply gamma, is the name of a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems.
You need adjust 4+3 gamma for different samples based on the color coordinates and target gamma offered by PQ engineer. So each sample can get almost the same effect as PQ golden sample. The 4+3 gamma include 4 gamma based on 4 different color temperature (cool, normal, warm1, warm2) and 3 gamma related to SDR to HDR (cool, normal, warm).
For the automatic gamma correction, we can do as below, but please refer to “Gamma correction specification (v1.00)”for detail.
* Initialize the picture, turn off dynamic backlight, dynamic contrast, and set picture mode as computer desktop mode;
* Get the color coordinates (x, y, Y) and target gamma in the PDM of the target model;
* Open the factory menu of TV, Open the tools SIACP and main.vi on the PC, connect the equipment correctly (CA310, serial port, PC, TV);
* Fill the color coordinates (x, y, Y) target gamma, error range and time-delay in the main.vi tool that made by AOE, and save it;

Put the probe on the middle of the panel, and then run main.vi. The 4+3 gamma will be created and calibrated automatically and saved in the TV.
As 4+3 gamma is a new and good way for PQ especially for HDR, we need adjust it in the factory now. And if we do the 4+3 gamma, there is no need to adjust the white balance. But we need do the initial setup of white balance.
“How to do initial setup of white balance”
Note: The operation must enable factory “P” mode
Targets and Tolerances for all inputs
(According to company uniform LED color temperature standard of panel)
The measured and adjustable parameters should be mainly “x”, “y” coordinates.
The White Balance alignment and Automatic Gamma correction should be performed using a well calibrated and contact less analyzer (ex: Minolta CA210 or CA310). 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 centre.
The results should fulfil specification for each TV set offered by R&D and below tolerances:

For the 4+3 gamma the target value is 2.2 and error range is ± 0.05.
Note:We will add more project ID later.
Note: If we can do both of White Balance & Automatic Gamma correction. For some special models, please notice the information provided by Huizhou factory or PJM to choose which way to make it.

Cloning
Once a TV is well aligned and prepared (channels maps, volume, picture presets, …) , user can prepare golden clone image that can be copied on demand to all further TV production lot of same TV. To access cloning function, you can select “Factory menu USB Clone >All -Chanel List - EEPROM - Users Setting” , Scroll down to “TV to USB” or “USB to TV” and press RCU “OK ►” key to process. 4 BIN images can created, overwritten or read on USB stick (pen drive) depending on chosen template like following: “database-applications-database-***.db” . These files need to be used strictly with MT58SoC platform as depending on SW structure.
Other faster access methods via UART/IR command share available on enclosed SIACP requirements (rev. v8.31).
Note: This function is only useful on factory sita P mode. And in hotel mode, we can use it too, but only copy the information related to the hotel.
High Pot. and Insulating Resistance Tests
At the end of the process, a “High Voltage” and an “Insulating Resistance” tests are required to fulfil Safety
Electrical requirements (CEI 65065).
High Voltage Withstanding requirements --Insulating Resistance requirements
“Voltage” > 3500VAC - “Voltage” > 500VDC
“Max Leakage Current” > 10 mA - “Threshold Min” >4M Ω
“Test Time” >3 sec - “Test Time” >2 sec

At final process stage, it’s necessary to perform “Reset shop” before any packing to leave Factory mode and restore User default presets.
First you need to enable Factory Key. After that selecting “Factory menu àReset Shop”, then pressing RCU “OK ►” key. Other faster methods via UART-IR commands are available on enclosed SIACP requirements (rev. v8.31).
Note:A password might be required in case of Parental Control function is locked, use default “1234” password or “0423” super password to clean-up existing ones if forgotten.
