S*02 (4:3 Overscan Bright High), S*06 (4:3 Overscan Bright Low),
SM** (4:3 Underscan Bright High/Low),
SN** (16:9 Overscan/Underscan Bright High/Low) [Service Menu]
Notes: • Perform the following adjustment after completing the 1080/60i Brightness Ad-
justment.
• Set the SUB PICTURE ADJ. data in the Setup Menu to “00”.
• The SO value (see the description for the HDTV Brightness adjustment) becomes
the reference value for the following adjustments. When this data is changed, it
is required to re-adjust the data of all of the adjustment signals (HDTV, SDTV and
NTSC/PAL). When re-adjusting the 1080/60i signal, use the SI.
• When overscan data of a signal is changed, it is required to re-adjust the
underscan data of the same adjustment signal.
• When the 4:3 data of a signal is changed, it is required to re-adjust the 16:9 data
of the same adjustment signal.
• After completing the brightness adjustments, make sure that the Low-Light is
not deviated. If it is, it is required to perform the Low-Light adjustment again.
