Troubleshooting tips
Issue Possible Cause
No picture - red LED ON LED on continuously indicates no (compatible) video is available
on currently selected source.
Conrm that the correct video input is selected.
Check that the video signal cable is properly connected to the
display. Test cable with ‘known good‘ equipment.
Check display settings of the video source - ensure the
resolution is supported by the display.
Ensure brightness is turned up to a suitable level.
No picture - red LED OFF Make sure power is connected to an appropriate DC voltage
source, and that the fuse is tted or breaker is switched on. After
pressing power button, the red LED should blink as monitor
starts up, followed by momentary display of the logo on the
screen.
Image persistence Image persistence occurs when a ghost of an image remains
on the screen after the screen image has been changed. Unlike
a CRT monitor, an LCD monitor’s image persistence is not
permanent. To erase an image ghost, turn the monitor o for
several hours. To avoid this condition, do not leave the monitor
displaying the same image unnecessarily, for an extended
period of time.
