General Alignment Instruction
1.Usually, a color LCD-TV needs only slight touch-up adjustment upon installation. Check the basic characteristics such as height, horizontal and vertical sync.
2.Use the specified test equipment or its equivalent.
3.Correct impedance matching is essential.
4.Avoid overload. Excessive signal from a sweep generator might overload the front-end of the TV. When inserting signal markers, do not allow the marker generator to distort test result.
5.Connect the TV only to an AC power source with voltage and frequency as specified on the backcover nameplate.
6.Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts.
7.To protect against shock hazard, use an isolation transformer.

White Ratio (Balance) Adjustment
1.You can adjust the white ratio in factory mode (1:Calibration, 3:White-Balance).
2.Since the adjustment value and the data value vary depending on the input source, you have to adjust these in CVBS, Component 1 and HDMI 1 modes.
3.The optimal values for each mode are configured by default..
- Equipment : CS-210
- Pattern: MIK K-7256 #92 “Flat W/B Pattern” as standard
- Use other equipment only after comparing the result with
that of the Master equipment.
- Set Aging time : 60min
- Calibration and Manual setting for WB adjustment.
