VIDEO IN is set to NONE, but the monitor has a video error, or
is showing a blue screen.
When the VIDEO IN parameter is set to NONE, the AV2 outputs a
blue screen at 480i resolution. This blue screen cannot be disabled.
If the monitor does not support 480i resolution, the monitor may
display an error message.
Note: This condition can also exist when the VIDEO IN parameter
has been set up, but there is no active incoming signal.
The two-line OSD display does not appear on the video
monitor.
• Verify that the two-line OSD parameter under the Setup ->
Display Setup -> On-Screen Display menu is not set to OFF.
• Verify the video input source. The two-line OSD is supported
only at 480i and 576i resolutions when the incoming video
source is digital.
While using HDMI connections, the video monitor is behaving
oddly.
Connecting together all the components of your home theater
system with HDMI cables depends upon every piece of equipment
functioning in synchronization. If the timing of any one piece is out
of sync, then odd results can occur. For example, an out-of-sync
source might cause incorrect colors to appear on the screen, or to
shift all of the video to the left or towards the top of the screen. If
the video monitor sync is off, it might load the color spacing
incorrectly so that the screen appears to be all one color, instead of
displaying normal color. In short, an out-of-sync signal can cause a
number of odd results.
To correct the problem, the system needs to resync, which should
clear the error. Some out-of-sync issues are easier to clear than
others. Typically, power-cycling the AV2 will clear it, but some sync
issues don’t need a power cycle to resync correctly. We suggest that
you try the following:
1. Enter the OSD menu and then exit out again. This will resync
the video.
2. Put the AV2 into Standby mode. Wait 10 seconds. Then take
the AV2 out of Standby mode.
3. Power-cycle the AV2 by turning off the rear panel Power switch,
wait at least 10 seconds and then turn the rear panel power
switch to the ON position.
4. With the AV2’s rear panel power switch set to OFF, power-cycle
all other devices that are connected to the AV2, such as DVD and
CD players, projectors and monitors. When finished, restore
power to the AV2 by setting the rear panel power switch to the
ON position and then taking the AV2 out of Standby mode.
The AV2 is connected via USB to the PC, but the computer is
playing with the sound card, not the AV2.
This condition may exist if the media player was already active
when the USB cable was connected between the computer and the
AV2 processor. With the media player actively playing, it may not
“see” the USB connection. Close the media player, check the cable
connections and then launch the media player again. Now it
should see the USB connection and switch control to the AV2.
