INF6501a Hardware Guide
Possible Solutions
• Verify the power cord is properly connected to the power outlet and to the monitor.
Verify the Power button on the remote or keypad has been turned on (the front LED
•
should be green).
• 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.
• Resyncronize the image using the monitor keypad.
Adjust Color menu settings.
•
• Reset the unit to factory default 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 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.
• Power the device off and back on after a few seconds. Re-booting the device helps the
touchpad to re-synchronize.
• Make sure the batteries are installed in the proper orientation and are not dead.
• Verify you are pointing the remote at the table and are within 26' (8m) and 30 degrees
(horz/vert) of the sensor.
• 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.
• If using a sound bar, verify that the sound bar is connected properly and that the sound
bar power switch is turned on.
• If using a VGA source, verify that an audio cable is correctly installed between the
source and the monitor.
• Using the remote, verify the volume is turned up enough and not muted.
• If playing a video, verify the playback has not been paused and that the video's audio
has not been muted.
• An HDMI 1.3 (or higher) source and source device is required to hear audio via the
®
HDMI cable.
