Problem Points to check and possible solutions
4. Afterimages appear.
Do you use the screen saver or timer (p.20)
when displaying the same image for extended
periods of time?
Afterimages are particular to LCD monitors.
Avoid displaying the same image for extended
periods of time.
5. The screen has defective pixels
(e.g. appears slightly light or dark).
This is due to the characteristics of the panel
itself and not the LCD product.
6. Fingerprints remain on the screen.
Leaving the screen white may solve the
problem

does not operate.
The adjustment lock is probably on. To unlock
it, first turn off the monitor. Touch the power
switch while touching the enter switch, and
then turn on the monitor again (see p. 19).
Make sure the control panel switches are not
wet or soiled. Lightly wipe the surface of the
control panel, and try touching the switches
again with dry hands.
Make sure not to wear gloves. Remove any
gloves, and try touching the switches again
with dry hands.
