PRECAUTION OF LCD MONITOR

NLEL0545S02

I

When passenger compartment temperature is low, the LCD
monitor sometimes dims because of the brightness of the back
light (small fluorescent light) integrated into the LCD monitor
decrease. In this case, the refreshing rate of the picture also
becomes low because of the low response of the LCD moni-
tor. When passenger compartment becomes warm, however,
the LCD recovers the normal display.

I

Sometimes, black or bright dots peculiar to LCD monitor can
be seen on the display.

I

Back light sometimes flickers or darkens according to the total
consumption hours and the number of ON and OFF switching.
In this case, the back light should be replaced (display unit
assembly).
