Always respect voltages. While some
may not be dangerous in themselves, they can cause unexpected reactions that
are best avoided. Before reaching into a powered TV set, it is best to test the
high voltage insulation. It is easy to do, and is a good service precaution.
When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.

Equipments
·Color Analyzer CA-210.
·Video Pattern Generator Chroma2329.
·Color TV Pattern Generator PM5418/Fluke5418.

ADC Calibration
Signal and generator
PC: Chroma2329 Pattern 42,Timing 14(1024X768@60Hz 5 MOSAIC) YPBPR: Chroma2329
pattern 103, Timing 79(100% Color Bar,720p)
Steps of Calibration
1). Access to the Factory menu->ADC
2). select RGB source and see the 5 MOSAIC appear on the screen
3). Select AUTO ADC , Press the right button on the your remote to calibrate
the ADC automatically.
4). Select YPBPR source and Repeat step 5.3 .
When the OK appears the calibration has been finished successfully.
White Balance adjustments (Manual)
Before adjustment ,you must make sure the ADC status(only PC and YPbPr) is “success
“and Color Analyzer has been calibrated .Only AV1,YPbPr,PC,HDMI1 need to be
adjusted. HDMI1 should be the first.
Signal and generator
The pattern of the signal should be used are White (Chroma2329 pattern 113) and
Grey (pattern 114).
The format of signal are respectively 720P for HDMI1 (Chroma2329
Timing 69),PAL (Chroma2329 Timing38) for AV1,1024X768@60Hz(Chroma2329
Timing14) for VGA and 720P(Chroma2329 Timing79) for YPbPr.
Steps of adjustment
1).Enter the factory menu-> White Balance, select source HDMI 1 and Normal
Temperature.
2).Input grey signal in 720p format.
3).Change R-OFFSET and B-OFFSET to make sure the value of color coordination
equal to (X=0.280 +or-0.015;Y=0.290 +or-0.015).
4).Input white signal in 720p format.
5). Change R-GAIN and B-GAIN to make sure the value of color coordination equal
to (X=0.280 +or-0.015;Y=0.290 +or-0.015).
6).Repeat step 2—5 until both of the value of color coordination of
white and grey equal to (X=0.280 +or-0.015;Y=0.290 +or-0.015).
For COOL and WARM color temperature, just repeat step 2—5.The color
coordination we recommend for COOL and WARM color temperature is
respectively(X=0.270 +or-0.015;Y=0.270 +or-0.015) and (X=0.300 +or-0.015;Y=0.305
+or-0.015).
After the adjustment of HDMI1, you can switch to other source AV, PC and YPbPr
and repeat step 1—6 to do the WB adjustment.
Note: For some small size LED panel,the
color coordination of specifications is not X=0.280, Y=0.290,and we recommend
you adopt the values from panel specifications.
