horizontal dark and light lines appear. The number of lines
increases as you press the button. Now press the bottom (or top)
Adjustment Control button until the lines disappear and you

PROBLEM: There is no LCD Display
If there is no display on the LCD, please perform the following steps:
1. Make sure that the power indicator on the LCD monitor is lit,
all connections are secure, and the system is running on the
correct timing. Refer to the Addendum for information on
timing.
2. Turn off the LCD monitor and then turn it back on again. Press
the upper Function Control button (refer to Chapter 2) once and
then press either the upper or lower Adjustment Control button
several times. If there is still no display, press the other
Adjustment Control button several times.
3. If step 2 doesn’t work, connect your PC system to another
e xternal CRT monitor. If your PC system functions properly
with a CRT monitor but it does not function with the LCD
monitor and the LCD monitor’s power LED is blinking, the
output timing of the PC’s VGA card may be out of the LCD’s
synchronous range. Please change to an alternate mode listed in
Addendum or replace the VGA card and repeat steps 1 and 2.
4. If the PC (or Notebook PC) doesn’t function with the CRT
monitor either, check BIOS to see if there is a Simultaneous
Display setting under the display mode item. Set the BIOS
display mode to Simultaneous Display or CRT and try again. If
there is still no display, then there may be a problem with your
system. Contact technical support for assistance.
5. If the power LED is not lit, check to see if the AC power
connector is securely connected. If the power LED is not lit,
please contact technical support for assistance.
