a. Verify that the devices are obtaining an IP address.
If the devices are not getting an IP address ("Unable to get IP address"
message on the TV display), verify communication to the DHCP server.
b. Verify proper DHCP Option 43 configuration.
3. If the SV-4K stays at the loading screen with the progress bar, verify
communication with the Cisco StadiumVision Director server.
4. (Advanced) Verify that an HTTP request comes in to the /var/log/httpd/access_log
(use the System State Report [SSR]).
Look for a message like the following:
10.194.169.242 - - [13/Oct/2014:13:10:05 -0700] "GET
/StadiumVision/dmp_v4/scripts/boot.brs HTTP/1.1" 200 89403 "-"

Troubleshooting SV-4K TV and Video Display Problems
This section identifies some of the symptoms related to problems with the SV-4K
display problems:
l
Symptom: Black screen on the SV-4K TV display/no multicast video stream, Page
54
l
Symptom: No local control when external volume strategy configured, Page 55
Symptom: Black screen on the SV-4K TV display/no multicast
video stream
Troubleshooting steps:
1. Verify if multiple TV displays are showing a black screen for the same multicast
video stream.
2. If
multiple
TV displays are showing a black screen for the same multicast stream:
a. Verify the SV-4K LEDs.
b. If the SV-4K LEDs are in normal state, verify that the Cisco StadiumVision
Director server has power and is reachable.
c. If all TV displays are the same and/or new model, test with a different, known-
working TV display model.
d. (Advanced) Test with laptop connected to the same switch port/interface as
the SV-4K with a problem, and see if the problematic video stream can be
displayed using the open source VLC player.
