Troubleshooting
Problem
Check the following
There is a black dot or
dead pixel dot on the
screen
A missing pixel does not constitute an out of spec.
defective product
Cannot turn power on
Turn off the power supply, and check that the AC cord
or DC cord are securely inserted. After checking, turn
on the power supply again.
It takes time for image to
appear
Since the monitor processes various signals digitally
to reproduce beautiful images, it may take time before
images appear when it is turned on, input is switched,
or when the
mode is switched to “Multi Window”.
There are spots on the
screen
There may be electrical distortion from vehicles, trains,
high voltage lines or fluorescent lamps.
Bad color
Color density or tint control may not be adjusted
properly. (See the adjusted value of image.)
Image appears and
disappears
Input may not be connected properly.
When changing the scan
size, the top and bottom
part of the screen does not
show images
When using a video software program (such as a
cinema size program) with a screen wider than one in
the 16:9 mode, blank areas separate from the images
are formed at the top and bottom of the screen.
Image contour flickers
Due to the characteristics of the display control,
contour of animated parts of images may seem to
flicker, but that is not a breakdown.
Color is extremely bad
Input configuration
“RGB”/“YPBPR” may not be
selected properly.
The POWER indicator is
flashing orange
After checking the number of flashes, turn off the
power and contact the dealer where the monitor was
purchased.
