POSSIBLE SOLUTIONS
• Verify the power cord is properly connected to the power outlet and to
the monitor.
• Verify the power switch is ON and that the Power button on the remote or keypad has
been turned on (the front LED should be on).
• Plug another electrical device to the power outlet to verify that the outlet is supplying
the proper voltage.
• Verify that a source is active.
• The monitor may have overheated. Remove any objects blocking the vents.
• If attempting to display an external source, see "No image from external source" below.
• Verify that the monitor is turned on (the front LED should be green).
• Verify that connections between the source and the monitor have been
made correctly.
• Verify that the cables are in good condition.
• Verify the correct input source is selected and that the input signal is compatible with
the monitor.
• Adjust the color settings in the Picture menu.
• Reset the picture settings.
• Verify that connections between the source and the monitor have been made correctly.
• Verify that the cables are in good condition.
• Verify that the USB B to USB type A cable is plugged from the laptop into the monitor
correctly.
• Verify that the laptop's operating system is Windows® 7 or 8. (The monitor touchpad
does not support any other operating systems.)
• Remove all objects placed on the lip of the monitor and/or within 2" of the touchpad
screen.
• Disable the PiP feature.
• Power the monitor off and back on after a few seconds. Re-booting the monitor helps
the touchpad to re-synchronize.
• Make sure the batteries are installed in the proper orientation and are not dead.
• Verify the remote is turned on (the button is on the bottom of the remote).
• Verify you are pointing the remote at the table and are within 26' (8m) and 30 degrees
(horz/vert) of the sensor.
• Verify that the IR Control setting in the Advanced Option OSD menu is set
to Normal.
• Noise can occur when infrared communication equipment (for example, infrared cord-
less headphones) is used near the monitor. Move the infrared communication equip-
ment away from the monitor to eliminate the noise.
