PROBLEM: There is no LCD Display
If there is no display on the LCD, please perform the following steps:
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.
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.
If step 2 doesn’t work, connect your PC system to another external
CRT. 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.
If the PC doesn’t function with the CRT monitor neither, check
BIOS to see if there is a dual scan setting under the display mode
item. Set the BIOS display mode to Dual Scan or CRT and try again.
If there is still no display, then there may be a problem with your
system. Contact technical support.
If the power LED is not lit, check to see if the AC power connector
is securely connected. Verify that the AC adapter LED is lit. If the
AC adapter LED is not lit, please contact your dealer for assistance.
