10 Troubleshooting
This chapter recommends what to do if you have problems operating the DFS.
In case the DFS does not work correctly, please check the following items first.
･
Are the DFS 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?
･
For 4K format, is a 18 Gbps high-speed cable used?
･
Are specifications of connected devices matched to each other?
･
Are settings of the sink device correct?
･
Are there any nearby 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.
Problem Cause/Check item/Solution Page
●
Video output
Video is not output. [1] Are signals output from the source device?
If the input resolution is displayed in “INPUT STATUS”, check [3] to [4];
if “No Signal” is displayed, check [5] to [6].
55
[2] Set “ 8.3.7 Test pattern ” to a pattern other than “OFF”.
- If any test pattern is not output, check [7] to [9].
- If a test pattern is output, the source device may not output video.

[3] If the display device or AV amplifier does not support HDCP, audio is
not output when signal with content protection is input. Some
HDMI/DVI devices check if the connected device is HDCP compliant
and determines whether to output HDCP signal or not. Since the DFS
is HDCP compliant, audio may not be output if the DFS is connected
to a sink device or AV amplifier that does not support HDCP. In this
case, disable HDCP input from the input device in “ 8.6.2 HDCP input
mode ”.
36
[4] Change the setting of Hot plug ignoring duration. 30
[5] The set time for monitoring no-signal input may be too short. 35
[6] If the source device has multiple output connectors, check the video
output settings of the source device.
－
Video is disappeared,
interrupted, or has
noise.
[7] If using a long cable for input or output, replace it with a 16.4 ft. (5 m)
or shorter cable. Since the DFS has the equalizing function, long
cables can be connected, but the DFS may not provide its full
performance depending on the cable quality and the connected
device. If the problem is solved by replacing the cable, signal may
have been degraded due to the long haul transmission. We have
high-quality cables, cable boosters and extenders. Please contact us
as needed.
