The HDL300 has stopped responding

When the RJ-45 jack on the Connect Module or the Integrated Microphone and Speaker Bar is disconnected and reconnected rapidly, some (or all) of the following problems may occur:

  • The system locks up (stops responding)
  • The integrated microphone and speaker bar stops responding to remote commands
  • No microphones pick up sound
  • The speakers stop working
  • The LED indicator on the integrated microphone and speaker bar stays on white


To troubleshoot

  1. Unplug the power for several seconds. Reconnect the power to reset the system.
  2. Unplug the RJ-45 connection from the integrated microphone and speaker bar for several seconds. Plug the connection back in.


If the steps above didn't work, proceed to

  1. Double-check the Ethernet cable wires are correctly crimped into the RJ-45 jack and are making contact. The electrical continuity of the cables can be checked with a multimeter.
  2. Make sure that the contact pins on the RJ45 jack are not bent, deformed or missing
  3. Ensure the RJ45 jack is secured in the receptacle connector with the locking latch (clip)
