Troubleshooting
No power
• Make sure power button (or switch) is ON.
• Make sure A/C power cord is securely connected to the AC/DC adapter
supplied with the ViewPanel
®
, then connected to a power outlet.
• Plug another electrical device (like a radio) into the power outlet to verify
that the outlet is supplying proper voltage.
Power on but no screen image
• Make sure the video cable supplied with the ViewPanel is tightly secured to
the video output port on the back of the computer.
• Adjust brightness and contrast.
• Macintosh
®
and workstation users: your system may require a cable
adapter. Verify that the settings on the adapter are adjusted correctly.
Screen image with horizontal "noise" or unclear characters
• Adjust the CLOCK PHASE control (see page 8).
"Outside Range Limits" message appears
• Verify that the output from your computer's video card is within operating
range: a refresh rate (vertical frequency) between 56 and 75 Hertz, and a
resolution of 1024 x 768 or lower. See the table on page 10 for supported
timing modes.
"Check Signal Cable" message appears
• If this message appears, check to make sure the video signal cable is
securely connected. Also check for Loose or broken pins in the cable
connector could cause an improper connection. NOTE: the power LED will
be lit amber.
• If the "Power Saving Mode" message briefly appears and the power LED is
lit amber, the ViewPanel is functioning normally.
