Improper NTSC/PAL setting
--------------------
Measure
Check that the parking brake is
engaged.
Adjust the brightness properly.
The temperature inside the vehicle
may be 0˚C or lower. Set to an ap-
propriate temperature (5˚C or so)
and check it again.

to prevent the glare (When the
headlight of the vehicle is lit in the
daytime, the display gets dark).
Set the AUTO/PAL/NTSC properly
according to the VTR.
This is not a failure, but a phenom-
enon peculiar to a liquid crystal
panel (The liquid crystal panel is
produced according to technology
with very high precision. Note that,
though there are effective pixels
of 99.99% or more, pixel missing
or normally lit pixels account for
0.01%).
