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 within 5% margin.
For example, check SoC voltage (AV3V3, VCCK-1V2, etc.), DDR voltage (DDRV) , amplifier voltage
(Main_Power), etc… Only the standby voltage is necessary if there is no software in the flash.
1.2. SW Image download
Download the latest release SW from below FTP server:

See Appendix ⑴“How to upgrade FLASH SW using MTK tool”
See Appendix ⑵“How to upgrade FLASH SW using USB”
OAD Transport Stream Image
To manage quicker mass reflashing, a predefined OAD DVB-T channel (freq:850MHz / bandwidth:8MHz) is
embedded to SW core and only available into Factory mode. Some licensed IBL tools ('xxx2lli.exe', 'lli2dsm.exe',
dsmmerge.exe, …) from Intellbyte Inc. (http://www.intellibyte.com/) might be necessary to create appropriate DVB
SSU TS. Over some predefine settings such as repeated datablock insertion, null packets size, … (controllable in
configuration file), here below are mandatory OUI entries structure to prepare DSM-CC carousel image format:

TCL_HW5881.pdf
To build an OAD TS, it’s necessary to create a temporary common and interchangeable DSM file format using
below command and arguments:
‘bin2dsm.exe -v -v -v -m0,0,"TCL_HW5881",0-n200 -z102400 -nz -o%FILE%.dsm -h"OUI=CUST_OAD_OUI
model=CUST_OAD_HW_MODEL version=CUST_OAD_HW_VERSION vm=0xffff" -s"OUI=CUST_OAD_OUI
model=CUST_OAD_SW_MODEL version=CUST_OAD_SW_VERSION vm=0xffff" %FILE%.pkg’
Then, OAD TS can be completed using below command and arguments:
‘dsmsectn.exe -v -dvbssu -mpegts -patpmt -nit_ter -sdt -o%FILE%.ts -gTCL_HW5881.dbc %FILE%.dsm’
For more robustness, TS can be played with following presets such as modulation:QAM-64, guard interval:1/8,
coding rate:2/3 to ensure ~22Mbps.
OAD reflashing process is managed within 4 steps operation: multiplex detection, DVB transfer, flashing and
warm-start.
See Appendix ⑶“How to upgrade FLASH SW using OAD”
1.3. UART & IR Parser
To use both UART and/or IR parser, TV has to be set in Factory mode with its VGA 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 SoC’s RS232 mode is automatically enabled at power-on and doesn’t require any command initialization
frame. <0x30 0x30 0x30 0x2E 0x30 0x65 0x30 0x74 0x30 0x0D 0xE2> from host to TV.
So correctly setup UART parser engine for further serial communication, it’s necessary to send following
command frame <0xAA 0x06 0x10 0x01 0xA7 0xEF> within following COM presets 115200/8/n/1; “PS” caption
might be toggled and displayed on bottom left screen (“S” like Serial) if successfull.
To communicate with TV depending on SIACP revision layout implementation, you may need to fulfill UART/IR
commands protocol and format described on enclosed SIACP requirements document (rev. v5.9).
SIACP_V5.9.pdf
1.4.ProjectID Modification
There are different IDs stored into system memory 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 PaneID with
Hyper terminal as other ID features may not change!
To modify ProjectID, you need to go through “Factory menuOtherProject infoProject ID”, then spin left
or right with RCU “◄/►” key” keys to suitable ID (Project name is dynamically refreshed).
See Appendix ⑷“How to change ProjectID with RCU”

Test and Alignment Specification for MT5331 Series (v0 91)

2.Product Assembly (PA): Test and 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 press “OK” key to enter into Picture 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 “Factory Key” can be changed in “Factory Menu->Hotkey”
Press RCU “OK/►” key to 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.

While “FactoryKey” is enabled, there’re some toggled display informations (~2s) relative to SW, ProjectID, CI+,
NetworkID to facilitate 100% quick screening without accessing to whatever else menu:
Firmware Version (MV) - ‘V8-0MTxxxx-LF1Vyyy’
Project ID (ID) - range [000..999]
CI KeyActivation flag (CI+) - ‘NO’= no key, ‘YES’= key activated
HDCP Key (HDCP) - ‘NULL’= no key, ‘YES’= key activated
PVR flag (ERG) - ‘OFF’= disabled, ‘ON’= enabled
P(Production/Factory mode flag) / S(Factory UART Parser mode flag) / W (Warm-Up mode flag)
2.2.Channel Map Preset
Region channel Maps are stored in the firmware and can be directly preloaded via Factory menu.
Other faster methods via UART/IR commands are available on enclosed SIACP requirements (rev. v5.9).
See Appendix ⑼“Factory Menu Description”
2.3.Warm-up Test
Following TCL standard and practices, it’s required minimum 15min of Warm-Up that can be considered as
Burn-In.AdditionalAging for White Balance alignment is no more necessary due to consistent Picture Performance
with Cloning usage.
This function is accessible by selecting “Factory menu Burning Mode”, pressing RCU “OK/►”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. v5.9).
2.4.White Balance (WB) Cloning
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 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.

Make sure Picture Preset is set to “DYNAMIC” mode, both “Contrast”and “BackLight”bargraph are set to
“100” (maximum), “Gamma” bargraph are set to “0” (2.2 nominal) and that both “Energy Saving” and “Light
Sensor”are set to “Off”from “ECO Settings” subsection.
Ensure that TV is in Factory mode to access to ”White Balance” adjustment submenu, then scroll down to
toggle off “Pic. Enhance” flag.
PC VGA, CMP YPrPb, SCART RGB,CVBS_PAL/SECAM Gain/Offset matrix offsets locations are relative to
HDMI/DTV.
Warm and Cool Tone are relatives to Normal mode. WB adjust need to fix default G Gain .
“Gain” registers set need to be adjusted at 70IRE.
“Offsets” registers set can be adjusted at 30IRE, but it’s not recommended to keep them defaulted.
Note: All matrix offsets locations can be individually fine-tuned.
Targets and Tolerances for all inputs
Note: The White balance value is right conformed by PQ Engineer , Except PQ Engineer, anybody can
not change the white balance value and Default value.
The measured and adjustable parameters should be mainly “x”, “y” coordinates (see “TCL EU Picture Quality
Requirements for FPDs” for reference).
The signal level check has been down in R&D, Factory should not adjust the scaling Brightness , scaling
contrast and scaling saturation.
The White Balance alignment should be performed using a well calibrated and contact less analyzer (ex:
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 following TCL matching requirements (Minolta CA210-CH00 based):

Cloning
To operate master/golden clone and reuse it further on demand, please to follow below Cloning SOP:
Cloning Procedure
for MT5531 Series (v1.00).pdf
All underused BIN image files need to be used strictly with MT5531 SoC platform as depending on SW
structure.
Other faster access methods via UART/IR commands are available on enclosed SIACP requirements (rev.
v5.9).
2.4.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” 3500 VAC - “Voltage” 500 VDC
- “Max Leakage Current” 10 mA - “Threshold Min” 4M Ω
- “Test Time” 5 sec - “Test Time” 3 sec
2.5.SHOP-END Test
At final process stage, it’s necessary to perform “Reset shop” before any packing to leave Factory mode and
restore User default presets.
This function is accessible by selecting “Factory menu Reset Shop”, then pressing RCU “OK/►” key. Other
faster methods via UART/IR commands are available on enclosed SIACP requirements (rev. v5.9).
“ResetShop” presets should follow “MT5531_EU_OOB_MenuSetting_step1_Base_01.doc” document.
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.
