LCD screen problems
LCD stands for Liquid Crystal Display, and it is very sensitive to
temperature.
If you have placed Scanner in a cold or hot place, the display may
become too dim or too dark when turned on. This is not a defect of
Scanner itself, but a normal response of all LCD's to the change of
temperature.
This is not a defect of Scanner.
However, if you cannot control the contrast using the dial, please
contact us for further assistance.
The LCD unit of Scanner has a backlight for brighter display. This
backlight generates heat as time elapses when turned on.
As mentioned above, because LCD is sensitive to temperature, the
part of the LCD near the backlight may turn dark when you keep DCN
turned on for more than 2 hours.
This is not a defect of Scanner.
However, if the LCD becomes dark too early or the contrast adjustment
doesn't work, please contact us for further assistance.

Report to your local distributor

distributor and wait for instruction.
Replacement of the LCD module may be necessary.
