Usually, a color LCD-TV needs only slight touch-up adjustment upon installation.
1.
Check the basic characteristics such as height, horizontal and vertical sync.
Use the specified test equipment or its equivalent.
2.
Correct impedance matching is essential.

4.
of the TV. When inserting signal markers, do not allow the marker generator to distort test result.
Connect the TV only to an AC power source with voltage and frequency as specified on
5.
the backcover nameplate.
Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure
