1.5.AD Calibration Test
As SoC as built-in A/D self-calibration mechanism, there’s not any ADC to perform.
1.6.DDC & EDID & T-Link Test
The E-EDID data structures are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for
HDMI). CEATiming 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 HDMI switch 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.
1.7.
HDCP Test
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set.
1.8. LAN/WLAN Test
(MAC address and Device/User ID codes)
MAC Address Upgrade

Factory Test & Alignment Specification For MS08PA-LA Series (V1.0).Doc
Page 6 of 18
See Appendix “How to upgrade MAC Address

DeviceID (DID) and UserID (UID)
Purpose is to allow Other Network Download (OND) and further specific Services over dedicated
portal based on UK.
Description/Portal Links/Flow chart are welcome?
For such, specific DID (32 bytes) and UID (8 bytes) needs to be paired and overwritten into
memory for internal client encryption.
Here are below codes examples:
Device ID User ID
BE4F255BBD106BC8F806AE456350D91F 3546187
Those DID/UID codes can only be set using UART commands following enclosed SIACP
requirements (rev. v3.9).
SIACP v3.9
(EN_20110613).pdf
See Appendix “Instructions of Updating DID,UID and MAC
”

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 “User menuSettingNetwork
SettingCabal NetworkOK” (ensure that “Internet Connection” is Enabled at first).
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.
Note:
It’s not necessary to check video and audio from DLNA server.
See Appendix “NETWORK CONNECTION AND TEST”


As some color coordinates discrepancies can be noticed from panel batches to others, it may
necessary to perform slight touch-up.
White Balance 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.

Factory Test & Alignment Specification For MS08PA-LA Series (V1.0).Doc
Page 8 of 18
Make sure that Picture Preset is set to “VIVID” mode, “Contrast” bargraph is set to maximum
(100%) and “Active Backlight” is set to “Off”.
Ensure that TV is in Factory mode to access to ”White Balance” adjustment submenu, then
scroll down to toggle off “Pic. Enhance” flag.
CMP YPrPb, RGB,CVBS_PAL Gain/Offset matrix offsets locations are relative to HDMI/DTV.
CVBS_SECAM and CVBS_NTSC Gain/Offset matrix offsets locations are relative to
CVBS_PAL.
Warm and Cool Tone are relatives to Normal mode.
“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.
The measured parameters should be mainly “x”, “y” coordinates.
Targets and Tolerances for all inputs
The “Y” peak luminance measurement at 100IRE is depending on achievable panel
performance and less important than saturation on high light. If necessary, “Scaling Contrast”
register can be adjusted.
The “BlackLevel” measurement need to be within 1% ±2. If necessary, “Scaling Brightness”
register can be adjusted.
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 result should fulfill TCL matching specification (Minolta CA210 reference with CH00):
MODEL COOL(x/y) NORMAL(x/y) WARM(x/y) ID
L32S4600 0.257/0.276 0.266/0.293 0.297/0.324 001
within below tolerances:
for Alignment: ± 0.003
for Measurement: ± 0.015
2.4.
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 SHOP init”, then pressing RCU “OK”
key. Other faster methods are available on above enclosed SIACP requirements (rev. v3.9).
