Cause
The parking brake is not
engaged.
The brightness control is too
low.
The operating condition is not
good.
The headlight of the vehicle
is lit
Improper NTSC/PAL setting
--------------------
Measure
Check that the parking brake
is engaged.
Adjust the brightness properly.
The temperature inside the ve-
hicle may be 0℃ or lower. Set
to an appropriate temperature
(25℃ or so) and check it again.
The display is made dark at
night 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 phe-
nomenon 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%).
