5 TROUBLESHOOTING GUIDE
No Power Indicated: The power plug may be loose or
disconnected.
Resolution: Insert the power plug firmly into the socket.
Power On, No Display: (1) No video signal connected; (2)
Video cable is disconnected.
Resolution: (1) Select and push correct video input button; (2)
Check video cable for proper connection and correct accordingly.
Power On, No Sound: (1) Incorrect cable connection
configuration; (2) Audio cable is disconnected; (3) Volume
output is set too low.
Resolution: (1) Ensure that cable connection configuration is
correct (see Section 2.5); (2) Connect audio cable firmly;
(3) Adjust speaker volume via OSD menu.
Display Jitter: The monitor may be close to a device generating
a strong magnetic field.
Resolution: Move the device away from the monitor until
picture stabilizes.
No Color, Incorrect Color, or Dark Color: The picture control
setting (e.g. Tint, Color, Brightness, or Contrast) may be set
improperly.
Resolution: Reset each picture control setting to the mid-range
level, or restore the factory DEFAULT setting in the OSD
menu.
Unnatural Color, Irregular Color, or Distorted Picture: The
monitor may be close to a speaker, magnet, or any other device
generating a strong magnetic field.
Resolution: Move the device away from the monitor and
discontinue power to the monitor. Wait at least 3 minutes, then
restore power to the monitor.
Picture Overexposure: The video input signal is not terminated.
Resolution: Ensure that the impedance switch on the rear panel
for that channel is set to the 75 Ω position, which properly
terminates the signal.
A Blank Display in Sequence Mode: Upon power-up, the
monitor memorizes the system configuration (i.e., the number or
video inputs which are connected). If a video input is added
after power-up, that signal will NOT be displayed in sequence
mode.
Resolution: Turn off the monitor for a few seconds, then power
up again. The additional signal should now be included in the
sequence mode.
