Points to check with Possible Solutions
|
1. No picture
|
-
Check that the power cord is correctly connected. If the problem persists, turn off the monitor power for a few minutes, then turn it back on and try again.
|
|
-
Check the "Brightness" setting.
|
|
|
-
Indicator status: Slowly flashing Yellow
|

Try pressing the Power button.
|
2. Error messages shown below will remain on the screen for 40 seconds.
|
These messages appear when the signal is not
inputted correctly, even if the monitor functions properly.
-
When the image is displayed correctly after a
short time, there is no problem with the monitor. (Some PCs do not output the signal soon after
powering on.)
-
Check that the PC is turned ON.
-
Check that the signal cable is properly
connected to the PC or graphics board.
-
Switch the signal input by pressing the Input
signal selection button on the front control panel.
|
- The signal frequency is out of range. Error signal frequency will be displayed in red.
(Example)
|
-
Use the graphics board's utility software to change the frequency setting. (Refer to the manual of the graphics board.)
|
3. Display position is incorrect.
|
-
Adjust the image position using the <Position> .
-
If the problem persists, use the graphics board's utility software to change the display position if available.
|
4. Screen image is smaller or larger than the actual screen images.
|
|
5. Vertical bars of distortion appear.
|
-
Decrease the vertical bars using the <Clock> .
|
6. The characters and images have several vertical bars on their right side.
|
-
If using the monitor in the analog input signal, try setting the Gamma value from 1.8 to 2.2.

7. Horizontal bars of distortion appear.
|
-
Decrease the horizontal bars using the <Phase>.
|
8. Letters and lines appear blurred.
|

-
This happens when both composite (X-OR) input signal and separate vertical synchronizing signal are input. Please select one of the two.
|
10. The screen is too bright or too dark.
|
-
Adjust the <Brightness> (The backlight of the LCD monitor has a fixed life span. When the screen becomes dark or begins to flicker, please contact your dealer.)
|
11. Afterimages appear.
|
-
Do you use the screen saver or timer 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.
|
12. The screen has defective pixels (e.g. slightly light or dark).
|
-
This is due to the characteristics of the panel itself, and not the LCD product.
|
13. Fingerprints remain on the screen.

Leaving the screen white may solve the problem.
|
14. The noise appears on the screen.
