Troubleshooting Checklist - Video Cart

The following checklist is based around a video cart system.
  • CODEC won’t turn on
    • Check power connections to the CODEC.
    • Check to make sure an electrical breaker has not switched off.
  • Video display (TV or LCD projector) does not connect to CODEC
    • Check power connections to the video display.
    • Check to make sure that the monitor or projector is set to correct input source (HDMI1, HDMI2, RGB, etc.)
    • Check to make sure that your camera input on your codec is selected.
    • If you have no picture on the monitor or projector, make sure cables are properly connected on the display and that the display cable is connected to the display  output on the codec.
  • CODEC and Display both work but the CODEC will not connect to a remote site – it will not ring out.
    • Check to see if your IP address appears on the menu/dial up screen.  If not you may not be connected to the internet.
    • Check to make sure the internet is working by calling another address within your own school.
    • Check to make sure the ethernet connection to the wall port is an active port.
    • Check to make sure the ethernet connection is in the correct port on the back of the CODEC.
    • Change ethernet cables to make sure the cable is good.
  • Audio Checklist:
    • Check that your speaker system is connected.
    • Check that both near and far ends are not muted.
    • Check that the volume is turned up on your monitor or projector display.
    • Verify that the audio out cables are properly connected to the display.
  • Echo Cancelling Problem – You are getting an echo back of your voice when you speak:
    • The problem is caused by another site which is getting feedback into their mics.  Follow these steps:
      • Identify the site that is the problem.  If there is more then one site, have each site mute their audio until you determine who is the problem.
      • When the site is determined, they should make sure that the audio on their codec remote system is turned up and then the audio level can be adjusted on their monitor/projector down.
      • If they are connecting on a laptop, they may need to add headphones to get rid of the feedback into the computer.
  • Cannot add technology such as a document camera or computer to display.
    • Click the input button on the codec remote to see if the doc cam or computer are connected.
    • Check the video inputs/outputs to make sure they are correctly connected.
    • If it is a computer, make sure that the video is mirrored to the connection.
  • Computer image will not fill entire screen.
    • Change resolution in your display settings of your computer.
  • Other troubleshooting problems
    • Remote control will not work – change the batteries.  (You should change batteries once a year)
    • If you experience poor motion handling or visible tiling in the far end picture during a video call, you are probably experiencing a data transport rather then an equipment problem.  Contact your ESU.
