Appendix C
Troubleshooting
This LCD monitor comes pre-adjusted with standard VGA timing. Due to output timing
differences among various VGA cards, you may initially experience an unstable or unclear
display when a new display mode or new VGA card is selected.
Before applying any of the following troubleshooting procedures, you should first apply the Auto
Adjust option in the OSD menu.
PROBLEM: Display is unclear and unstable
To stabilize and clarify your display, open the OSD and adjust the clock and
phase to obtain a clear display
PROBLEM: There is no LCD display
If there is no display on the LCD, refer to the following:
1. Make sure that the power indicator on the LCD monitor is lit,
that all connections are secure, and that the system is running
on the correct timing. Refer to Appendix B for information on
timing.
2. Turn off the LCD monitor and then turn it back on again. Press
the OSD Menu button (refer to Chapter 2) once and then press
one of the Adjustment Control buttons several times. If there is
still no display, press the other Adjustment Control button
several times.
3. If step 2 does not 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.
Change to one of the alternate modes listed in Appendix B, or
replace the VGA card and repeat steps 1 and 2.
