Troubleshooting
• Turn on the main power.
• Check that the AC power cord is connected correctly.
• Brightness of the power indicator may be turned off. Turn it on and
check once more.
When the power indicator does not turn on:
• Turn on the main power.
• Check that the AC power cord is connected correctly.
When the power indicator is lit orange:
• Press the button.
When the power indicator is flashing orange:
• Flashing once every 3 seconds : Contact Canon Customer Center.
• Flashing twice every 3 seconds : T urn on the power with the button.
• Check that the main unit and the display controller are connected
correctly.
• Pairing may not be performed correctly. Try re-pairing.
• Set each item in "Channel Settings" according to input signal.
• There may be no input signal. Look at the display area icon in the
interface area and check that the input area and signal cables are
properly connected.
• Signals with different resolution or frequency may be input from each
terminal. Check the signal.
• Adjust the "Contrast" on the OSD menu.
• There is a limit on the service life of LCD backlight. If the screen
becomes dark or starts flickering, contact Canon Customer Center.
• This is a characteristic of the LCD panel and you should avoid displaying
stationary image for a long time.
• LCD display is made of very high precision technology. It has effective
pixels of 99.99% or more, but there may be black dots or red, blue, or
green dots that may be always on. This is not a failure.
• The symptom may be resolved by displaying a white or black image on
the entire screen.
• Check that "Protect Settings" is not set.
• A channel with no signal, unsupported signal, or with "Input
Configuration" not set may be selected. Check the signal.
• "H Delay"/"V Delay" is turned "On". Set to "Off".
• Not displayed when "Peaking 1" or "Peaking 2" is selected. Set it to
"Off".
