Measurements
For the best result, measurements are performed in a straight angle to the LCD
panel, meaning that you must be looking into the reflection of your own eye.
The television must be on for minimum 20 minutes before measurements may be
started.
This is due to the backlight which does not reach a 90% level until 20 minutes
have passed.
The test signal is applied to the V.TAPE input, SCART connector, unless differently
specified.
Preparations before check and adjustment
1. Switch the television on.
2. The television must warm up for minimum 20 minutes before adjustment can be
performed.
The backlight reaches 90% efficiency after app. 20 minutes.
3. Select the correct test picture.
4. Set the television in the correct FORMAT.
