If the output is black or has no signal, here are some things to examine. This article applies to UltraNEXUS-HD, UltraNEXUS-HD X2, X5, Flex, Cast, and Blade servers.
Issues that can cause the UltraNEXUS-HD to have no output include problems with files or schedule playback, the unit is not powered on or running, or issues with how the output is being monitored.
UltraNEXUS-HD RUNNING?
- Ensure the UltraNEXUS-HD is running, and you can connect to it with the WinLGX software or web interface.
- If you can't, review the "Cannot Connect to UltraNEXUS-HD Series Server" tutorial linked here: https://support.leightronix.com/cannot-connect-to-ultranexus-hd-series-server
VIDEO OR SLIDESHOW PLAYING?
- Check the WinLGX Control Panel window.
- In WinLGX, go to the TOOLS menu and select CONTROL PANEL
- Make sure the Player tab at the top is selected.
- You should see either a video file playing or your slides playing.
- It should show the video file name or the slide file name on the right side.
- If nothing is listed as playing:
- Check to see if the file or slide failed to play
- See the following tutorials linked below:
- Check to see if the schedule is running
- Check to see if the file or slide failed to play
SCHEDULE RUNNING?
- Check the Schedule Button in the lower left of the Control Panel
- If the Schedule button is green and says "Stop Schedule," the schedule is active and running.
- If it is red and says "Start Schedule," the schedule is not running.
- You'll want to click it to start the schedule, and it will wait to start playing at the next scheduled event.
WILL IT PLAY A FILE?
- You can also try manually playing a bars and tone file to check the output.
- See the tutorial linked below:
- How to Manually Play a Video File
BLACK SIGNAL VIDEO?
- Make sure the playing file has video and is not a file that is just a black video.
- Play the video file in the WinLGX software preview monitor to see if the video is black in the video file itself.
- In WinLGX, open the Storage Manager window (Tools/Storage Manager).
- Find the video file and right-click it to open the menu on the right side.
- Select View, and the preview monitor should open and begin playing the file.
SWITCHED CORRECTLY?
- If Using an External Video Switch:
- If you are using an external switch and it's switched to another input on that switch, check to see that that input is working and has a video signal.
- If the UltraNEXUS-HD is playing a file, make sure it is switched to the correct output.
MONITORED CORRECTLY?
- Check how you are monitoring the video output.
- There are generally two ways to view the video output of the UltraNEXUS-HD – using the cable return or from a directly connected monitor.
- Cable Return
- Suppose you watch the video after it goes out to your cable channel and comes back from the cable channel. That is too long of a signal path to diagnose the UltraNEXUS-HD because it's going through all the cables and other devices downstream from the UltraNEXUS-HD, and one or more of those cables or devices could be the culprit introducing the issue.
- Direct Monitor
- SDI Output
- If using the SDI output of the UltraNEXUS-HD, you'll need to connect the output directly to an SDI monitor.
- Or you can use an SDI to HDMI converter and connect that to an HDMI monitor to see if the video is present directly out of the UltraNEXUS-HD's SDI output.
- Or you can use an SDI to ANALOG converter and connect that to an analog/composite monitor to see if the video shows there.
- CVBS Output
- If using the CVBS composite output of the UltraNEXUS-HD, you should be able to connect that directly to a composite monitor to check the video output.
- If there is no video from the CVBS composite output:
- Check the output settings in the web interface, System Settings page under the System tab
- See the "Setting the Output Resolution of the UltraNEXUS-HD" tutorial.
- There will be no composite output if the output is set to 720p.
- Check the output settings in the web interface, System Settings page under the System tab
- SDI Output
NOTE: An UltraNEXUS-HD Cast or Flex does not have CVBS composite output capability.
- Suppose the video is present when watching from a direct monitor. In that case, the UltraNEXUS-HD unit is working correctly, and the problem is with the cables or devices downstream from the UltraNEXUS-HD.
- If the video is not present when watching directly from a monitor, then do a loop connection test (see instructions below).
Loop SDI Out to SDI In Test
- You can test by connecting a single video cable to the UltraNEXUS-HD's SDI output and the other end to the UltraNEXUS-HD's SDI input, then checking the signal it sees.
- You can see what kind of signal it's sensing in two ways:
- From the front panel: Press the up arrow until it displays, "SDI IN:"
- From the web interface Dashboard page: Lower right corner area.
- "Unlocked" means it doesn't sense any signal.
- If the looped signal says "unlocked," the unit may need to be repaired or replaced.
