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 Facto
ry mode to access to ”White Balance” adjustment submenu
, then
scroll down to toggle
off “
Pic. Enhance
” flag.
CMP YPrPb , R GB , CVBS_PAL Gain/Offset matrix offsets locations are relative to HDMI/DTV .
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 CA310 reference with CH09):
MODEL COOL(x/y) NORMAL(x/y) WARM(x/y) ID
L32D2900 R/G/B offset
-5/0/12
0.270/0.275 R/G/B offset
12/0/-20
009
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).
