10 Troubleshooting
This chapter recommends what to do if you have problems operating the MSD.
In case the MSD does not work correctly, please check the following items first.
･
Are the MSD and all devices plugged in and powered on normally?
･
Are cables connected correctly?
･
Are there no loose connections?
･
Are correct cables supported by devices being used?
･
Are signal specifications of connected devices matched to each other?
･
Are settings of the sink device correct?
･
Are there any close objects that may cause noise?
If the problem still cannot be solved, perform the following actions. Refer to manuals of connected devices as
well, since they may possibly be the cause of the problem.

●Video output
Video is not output.
Check the error code in “
8.15.2 Sink device status (P.108)
”.
(Since the
MSD has multiple output connectors, check the error code of the output
connector that does not output video.)
・
Error message: “Not DDC Power”
Check if the source device is connected and turned on.
・
Error message: “No Signal”
Signal is not input. Check [1] to [5] on the next page
・
Error message: “AV Mute Received”
A problem may occur in the source device or HDCP authentication.
Check [2], [4] and [5].
・
Error message: “HDCP Video Mute”
With using a sink device that is not HDCP compliant, only video
without content protection (such as analog input and test pattern) can
be output, and go black if signal with content protection is input. Some
source devices check whether the sink device is HDCP compliant or
not and output video depending on the result. Since the MSD supports
HDCP, output video cannot be output if the sink device is not HDCP
compliant. In that case, you can disable HDCP input from the source
device in
8.6.2 Setting HDCP input (P.53)
”
in order to display the
video.
・
Error message: “Not AVIInfoFrame” or “Dot Clock Over”
A problem occurs in the source device.
・
Error message: “Channel OFF”
Set “
7.2 Switching input channel (P.22)
”
to a value other than “OFF”.
