Problems Points to check with possible solutions
4. The screen is too bright or too
dark.
Adjust the <Brightness>. (The backlight of the LCD
monitor has a fixed life span. When the screen
becomes dark or begins to flicker, please contact
your dealer.)
5. Afterimages appear.
When the screen image is changed after displaying
the same image for a long period, an afterimage
may appear. The “Afterimage” can be removed
gradually by changing the displayed image. Use the
“Off Timer” function and avoid keeping the screen
on all the time. (p.17)
6. The screen has defective pixels
(e.g. slightly light or dark).
This is due to the characteristics of the panel itself
and not the LCD product.
7. Fingerprints remain on the
screen.
Leaving the screen white may solve the problem.
8. “Locked!” message appears and
the adjustment controls are not
available when pressing the
Control Buttons.
After the calibration, the functions like brightness
are automatically locked. Please refer to page 18 to
unlock.
9. The Main menu of
ScreenManager does not
operate.
The adjustment lock is probably on. To unlock:
switch the LCD monitor off. Then, while pressing
the Enter Button, switch the power on. (p.17)
10. USB function cannot be setup.
Check that the USB cable is correctly connected.
Check that the PC and OS are USB compliant. (For
verification of USB support, consult the
manufacturer of each system.)
Check the PC’s BIOS setting for USB. (For details,
refer to the manual of the PC.)
