Peak-White Alignment
You can adjust the light output of the CRT in the WHITE TONE sub menu. In this case,
a color analyzer is necessary.
1. Set the pattern generator to a pattern having a white (100 % video) area and
connect RF output to aerial input. Set amplitude to 1mV.
2. Set the default settings as mentioned in the start of this chapter.
3. Measure with a color analyzer (calibrated with the spectra) on the center of the
white square on the screen. Adjust the levels of NORMAL RED, NORMAL
GREEN and NORMAL BLUE so that you retrieve a 390 cd light output for the 27
inch sets and 400 cd light output for the 32 inch sets.
Tuner (Large Signal Panel)
Note: Described alignments are only necessary when HIP or NVM is changed.
IF PLL OFFSET
Set the pattern generator (e.g., PM5418) to a color bar video signal and connect the RF
output to aerial input. Set amplitude to at least 1mV.
Alignment procedure:
1. Choose a known good channel.
2. Enter SAM mode and select TUNER
3. Align the IF AFC parameter so that you come into the AFC window, meaning that
the AFB value must be on the transient of going from 1 to 0 (see table below,
which explains the best way of aligning).
4. After this alignment, store the value by returning to the former menu (via
“MENU/SELECT” key).
5. Exit the SAM mode via the “Standby” button on the RC transmitter.
