  If your Altec Lansing Speaker System's LEDs are not lit, it could be due to several reasons. First, make sure the power is turned on by pressing the Power button on the wired controller or remote control. Check that the power adapter is correctly connected to both the wall outlet and the subwoofer by disconnecting and reconnecting it. If you're using a surge protector, ensure it's switched on. Also, verify that the wired controller is properly connected to the subwoofer. Finally, test the wall outlet by plugging another device into it to ensure it's functioning correctly.

  If you're not getting any sound from your Altec Lansing Speaker System, first ensure that the subwoofer's AC power cord is properly connected to both the wall outlet and the subwoofer.

Verify the audio cable is correctly connected to your audio source, ensuring it's firmly inserted into the correct jacks on both the subwoofer and the audio source. Finally, confirm that the audio cable is connected to the correct output on your audio source, leading to the input jacks on the subwoofer. If problems persist, test the speakers with an alternate audio source.

  If you're experiencing a loud hum from the subwoofer of your Altec Lansing Speaker System, and you're using a surge protector, try disconnecting the power adapter from the surge protector and plugging it directly into an AC wall outlet. If the hum persists, disconnect your stereo cable from the audio source; if the hum disappears, lower the volume on the audio source.
