Chapter 4 Troubleshooting
Possible cause and remedy
• Adjust <Brightness> or <Contrast> from the <Color>
menu.
(The LCD monitor backlight has a fixed life span. When
the screen becomes dark or begins to flicker, contact
your local dealer.)
• Use a screen saver or off timer function for a long-time
image display.
• Afterimages are particular to LCD monitors. Avoid
displaying the same image for a long time.
• This is due to LCD panel characteristics and is not a
failure.
• Leave the monitor with a white screen. The symptom
may disappear.
• When utilizing [ContrastEnhancer] and/or
[OutlineEnhancer] function, the normal images may not
be displayed since the display gradation abnormality or
noise may occur on the screen depending on the display
pattern.
• When [OutlineEnhancer] is set excessively, the
characters on the screen may be affected by color.
• Check whether the audio cable is connected properly.
• Check whether a headphone is connected to the
headphone jack.
• Adjust the sound volume. (Refer to page 23.)
• Adjust the volume difference between the equipment
connected by the <Sound Level> in the <Sound> menu.
(Refer to page 23.)
• Check whether the [Off Timer] function is set. Check the
[Off Timer] setting. (Refer to page 29.)
• Check whether "Disable" is set in the <Signal Detection>
of the <Monitor Settings> menu. (Refer to page 29.)
• The selectable menu items differ depending on the input
signal. So, please check the menu list.
(Refer to the menu list on page 41.)
• Check whether the switches are locked. (Refer to page
14.)
