Factory Test & Alignment Specification For MS08EP-LA Series (V1.0)
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.
Targets and Tolerances for all inputs
The measured parameters should be mainly "x", "y" coordinates.
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):

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).
