INFO:
All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage (220 ~ 240 VAC)
All voltages have to be measured with respect to ground, unless otherwise stated
All final tests have to be done on a complete set including LCD panel in a room with temperature of 25+/-7°C
The Picture Performance assessment such as Gamma Correction and White Balance (luminance and
colortemperature) 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(AVDD3V3,DVDD3V3,VCCK_1V0,AVDD1V0_STB,095VM,3V3SB, etc.), DDR
voltage (DDRV_1V5,1V5M) , audio amplifier voltage(24V AMP_VCC),etc...
Measurements should fulfill specification within ±5% tolerances.
Note①:See enclosed circuit diagram for more details.
1.2. SW Image download
Download the latest release SW from below FTP server:

1.2.1 LR or PR step. ---Only test
In case of starting from blanked flash / eMMC, it’s necessary to use “rticetool” to update the SW.
See Appendix ⑴“How to upgrade main SW using tool”
See Appendix ⑵“How to upgrade SW using USB”
See Appendix ⑶“How to upgrade main SWusing USB and RCU”
1.2.2 MP Step
In case of starting from blanked flash, it’s necessary to write “tcl.img” file via factory copy in advance.
OAD Stream(This function is not ready by SW)
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 ⑷“How to upgrade FLASH SW by OAD”
1.3. UART & IR Parser
To use both UART and/or IR parser, TV has to be set in Factory mode with its USB port well connected to suitable
UART device or an IR emitter device correctly facing up TV (see below “section 2.0- Product Assembly” how to
activate “Factory Hotkey”).
The UART parser engine is enabled by sending following command “0x10”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. v8.31).
1.4. Project ID Modification
There are different IDs stored into the eMMC 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 Panel ID with Hyper
terminal as other ID features may not change!
To modify ProjectID, first of all you need to enable Factory Hotkey (See below “section 2.0-Product Assembly”). After
that, go through1950 to “Main menu Service menu8-Project ID”, then turn left or right with RCU “◄/►” key”
keys to suitable ID (Project name is dynamically refreshed). Restart TV.
See Appendix ⑸“How to change ProjectID with RCU”
See below is the ProjectID table for reference:

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. v8.31).
- 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 ⑽“How to upgradeMAC Address using USB”
DeviceID (DID)
Purpose is to allow Other Network 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.

For such, specific DID (40 bytes) needs to be paired and overwritten into memory for internal client encryption.
All DID and MAC codes have to be download from portal local service via suitable factory workstation LAN system.
Then during production lot, it’s necessary to send/write all those codes to each TV.
DID codes can only be set using UART commands described above on enclosed SIACP requirements (rev. v8.31).
- Writing Device ID command <0xB2>, Data length <32>, Data type <ASCII> (see below command example from
above DID code)
<AA 25 B242 45 34 46 32 35 35 42 42 44 31 30 36 42 43 38 46 38 30 36 41 45 34 35 36 33 35 30 44 39 31 4648

LAN Test
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 “SettingsNetwork IP settings(Ethernet)”.
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”
Note③: It’s not necessary to check video and audio from DLNA server.

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.
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, press the menu button on
the TV panel. Other faster methods via UART/IR commands are available on enclosed SIACP requirements (rev.
v8.31).
2.3. 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:
Prop Name
Description
Value
Align_mode
WB alignment or
Auto Gamma correction
0 -- > WB 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/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 Normalmode.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
￭Automatic Gamma correction
Gamma correction, or often simply gamma, is the name of a nonlinear operation used to encode and decode

Test and Alignment Specification for RT2851 Series (v0.01).docx

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, 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.
See Appendix⒂“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 andAutomatic 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 center.
The results should fulfill specification for each TV set offered by R&D and below tolerances:
