Troubleshooting

If you are experiencing trouble with the LCD display, refer to the following.
If the problem persists, please contact your local dealer or visit Planar Support at
www.planar.com/support. See support contact information on rear cover.
PROBLEM: Picture is unclear and unstable.
The picture is unclear and unstable, please perform the following steps:
1. Enter PC to "Shut Down Windows" status while you're in MS-Windows environment.
2. Check the screen to see if there's any black vertical stripes appear. If there are,
take advantage of the "Clock" function in OSD menu and adjust (by increment or
decrement numbers) until those bars disappear.
3. Move to "Phase" function in OSD menu again and adjust the monitor screen to its
most clear display.
4. Click "No" on "Shut Down Windows" and back to the normal PC operating
environment.
PROBLEM: There is no picture on LCD Monitor
If there's no picture on the LCD Monitor, please perform the following steps:
1. Make sure the power indicator on the LCD Monitor is ON, all connections are
secured, and the system is running on the correct timing. Refer to Chapter 3 for
information on timing.
2. Turn off the LCD Monitor and then turn it back on again. If there is still no picture,
press the Adjustment Control button several times.
3. 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, the output timing of the VGA card may be out of the LCD's synchronous
range. Please change to an alternative mode listed in the Standard Timing Table or
replace the VGA card, and then repeat steps 1 and 2.
PROBLEM: There is no picture on LCD Monitor
If you have chosen an output timing that is outside of the LCD Monitor's synchronous range
(Horizontal: 31 ~ 93.75 kHz and Vertical: 50 ~ 76 Hz), the OSD will display a "Out of Range"
message. Choose a mode that is supported by your LCD Monitor.
Also, if the signal cable is not connected to LCD monitor at all or properly, the monitor
screen will display a message "No Input Signal".
