4.3 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.
