INFO:
ªAll tests and measurements mentioned hereafter have to be carried out at a normal mains voltage (220 ~ 240 VAC)
ªAll voltages have to be measured with respect to ground, unless otherwise stated
ªAll final tests have to be done on a complete set including LCD panel in a room with temperature of 25+/-7°C
ªThe Picture Performance assessment such as White Balance (luminance and colourtemperature) 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. PCB/SKD Assembly: Test & Alignment
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(3V3,1V8, CORE_1V9,5V, 5VSTB, etc.), DDR voltage (DDR_1V5), audio amplifier
voltage(12V),etc...
Measurements should fulfill specification within ±5% tolerances.
Note①:See enclosed circuit diagram for more details.

In case of starting from blanked flash, it’s necessary to write “emmc.upm” file via factory copy in advance.
OAD Stream//please delete it ,this mathine did not need this function to update software
To manage quicker mass reflashing on predefined DVB Channel, some licensed IBL tools ('xxx2lli.exe', 'lli2dsm.exe',
dsmmerge.exe …) from Intel byte Inc. might be necessary to create appropriate DVB SSU image. Over some predefine
settings such as repeated data block insertion, null packets size, … that are controllable in configuration file, here below
are mandatory OUI entries structure to prepare DSM-CC carousel image format:
- export CUST_OAD_OUI 0x001C50
- export CUST_OAD_HW_MODEL 0x5395
- export CUST_OAD_HW_VERSION 0x0000
- export CUST_OAD_SW_MODEL 0x0001
- export CUST_OAD_SW_VERSION 0x00
OAD reflashing is managed within 4 steps operation: multiplex detection, DVB transfer, flashing and warm-start.
See Appendix ⑶“How to upgrade FLASH SWand EEPROM Clone usingOAD”
1.3. UART & IR Parser
To use both UART and/or IR parser, TV has to be set in Factory mode with itsUSB port well connected to suitable
UART device or an IR emitter device correctly facing up TV (see below “Product Assembly - section 2.0” how to
activate “Factory key”).
The UART parser engine is enabled by sending following command “0xE2” from host to TV within following presets
115200/8/n/1.
Once initialized, “PS” caption is toggle displayed on bottom left screen (“S” like Serial).
To communicate with TV depending on SIACP revision layout implementation, you need to fulfill UART/IR
commands protocol and format described on enclosed SIACP requirements document (rev. v3.9).
1.4.Project ID Modification
There aredifferent IDs stored into theeMMC depending on different Panels settings and Models features, but there’s
only one key branching ProjectID that includes all. So, it’s not recommended to modify PaneIDwith Hyper terminal as
other ID features may not change!
To modify ProjectID, you need to go through“Factory menuÆOtherÆProject ID”, then spin left or right with RCU
“◄/►” key” keys to suitable ID (Project name is dynamically refreshed).It is necessary to press “OK” key for saving the
setting.
See Appendix ⑷“How to changeProjectID with RCU”
See below is the ProjectID table for reference:

Page 8 of 25
As SoC as built-in A/D self-calibration mechanism, there’s not any ADC to perform.
1.7.DDC & EDID & T-Link Test
The E-EDID data structures are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for HDMI). CEA Timing
Extension structure has been extended to support all 3D capable timings.
All HDMI structures have their own BIN profile which are part of main SW and uploaded at power-on into soc chipset:
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.
1.8.HDCP Test
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set by connecting suitable
generator.
1.9 CI+Key Upgrade, Activation and Test
See Appendix ⑹“How to upgradeCI Key using USB”
1.10.LAN and WLAN Test(MAC address and Device/User ID codes)
Here are some representative codes examples:
MAC Address Upgrade (IPv6)
MAC can be set using UART commands described on enclosed SIACP requirements (rev. v3.9).
- Writing MAC command <0xB3>, Data length <6>, Data type <HEXA> (see below command example from above
MAC code)
<AA 0B B3 00 1C 50 E2 B1 EC 36 78>
See Appendix ⑺“How to upgradeMAC Address using USB”
DeviceID (DID)
Purpose is to allow Other Newtork Download (OND) and further specific Services via dedicated abroad portal (UK
tbc).4 At final, when TV may ask for portal connection, there’ll be Device ID matching control sent by host (TV client)
to ensure total integrity.
Device ID User ID MAC Address

A rough LAN test can be done by connecting DHCP server to TV’s RJ45 and check that IP, subnet mask, DNS, …
addresses are visible on “User menuÆNetworkÆInternet connection(On)ÆIP settings”.
More in-depth test can be performed faster using suitable UART/IR commands following SIACP requirements. SW
will internally manage Network ID (NID) flag controlling all MAC/DID/UID integrity to facilitate PA screening further.
See Appendix ⑾“Network Connection Setup”
See Appendix ⑿“How to upgrade Flash SW using Network”
Note⑤: It’s not necessary to check video and audio from DLNA server.
2. Product Assembly (PA): Test & Alignment
2.1.Factory Menu
Follow the below steps to pop-up the Factory menu in case of “FactoryKey” is disabled:
- Press RCU “MENU” key to display main menu
- Select “Picture” and findpicture submenu
- Scroll down to“Contrast” item
- Press the subsequence RCU keys “9”, “7”, “3” and “5”
In case of “FactoryKey” is enabled,just press RCU “Return” key（）to pop-up again the Factory menu.

The status of “FactoryKey” can be changed in “FactoryMenu->Hotkey”
Press RCU “OK/►”keyto enter the submenu.
Press RCU “Menu”key to go back to the root menu.
Press RCU “◄/►” key to change the values.
Press RCU “OK”key run the function.
Press RCU “Exit”key exit the Factory menu.
Factory Captions Description
While “FactoryKey” is enabled, there’re some toggled display information (~2s) relative to SW, ProjectID, CI+,
NetworkID to facilitate 100% quick screening without accessing to whatever else menu:
Main SW Ver
FRC Ver(MEMC version)
Project ID(ID)
ERG(PVR)
CI Key Activation flag (CI+ key)
NID(Internet infor for factory)
P (Production/Factory mode flag) / S (Factory UART Parser mode flag) / W (Warm-Up mode flag)
See Appendix ⑨“Factory Menu Description”
2.2.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.
This function is accessible by selecting“Factory menu ÆWARM 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.
v5.4).
2.3.White Balance
White Balance Touch-Up (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 HDMIinput 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/high light saturation points.

Ensure that TV’spicture enhance is off.
Ensure that TV is in Factory mode to access to ”White Balance” adjustment submenu, then scroll down to
toggle off “Pic. Enhance” flag.
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.
¾“Gain” registers set need to be adjusted at 70IRE.
Targets and Tolerances for all inputs
(According tocompanyuniform LED color temperature standard of panel)
The measured and adjustable parameters should be mainly “x”, “y” coordinates.
The White Balance alignment 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 center.
The results should fulfill specification for each TV set offered by R&Dand below tolerances::
NT67 panel name Energy FW Min (Nits) Preset Targets (x, y)
Model Efficient FW>Min COOL NORMAL WARM

Targets Tolerances
COOL NORMAL WARM ALIGNMENT MEASUREMENT
Coordinate “x” Offered by R&D PQ engineer ± 0.003 ± 0.020
Coordinate “y” ± 0.003 ± 0.020
Important: If measurements are performed on whatever else LED panel with Minolta CA210, it’s required to
calibrate additional channel (ex: CH01) using relative following offsets (CH00 remains for CCFL panel):+0.002for “x”
and +0.012 for“y”.
Note⑧:See WB list as follows for more details.
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 ÆUSB Clone &&UpdateÆAll Clone/CH Clone/User data Clone” , 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 NT667SoC platform as depending on SW structure.
Other faster access methods via UART/IR commandsare available on enclosed SIACP requirements (rev. v3.9).
