How to fix Altec Lansing FX5051 Speaker System when no LEDs are lit?
- S
  Shane WilliamsAug 18, 2025
  If no LEDs are lighting up on your Altec Lansing Speaker System, it could be due to a few reasons. First, ensure the speaker system is turned on by pressing the power button on the control pod or wireless remote. Also, verify the AC power cord on the back of the subwoofer is securely plugged into a functioning wall outlet, and that the surge protector (if used) is switched on. To check the wall outlet, plug another device into the same jack to confirm it's working.

  If you're not getting sound from one or more speakers on your Altec Lansing Speaker System, here's what you can check: * Make sure the switch on the rear of the subwoofer is in the correct position. * Increase the rear or center speaker level. * Ensure the speaker system is powered on by pressing the stand-by button on the control pod or wireless remote, and that the AC power cord is plugged into a wall outlet. * Verify the volume isn't set too low, both on the control pod and on your computer's sound card or audio source device. * Check that the color-coded 3.5mm stereo cables are properly connected to the audio source. * Test the speakers with another audio device to rule out a problem with your primary audio source.

  Karen MorrisAug 23, 2025
  If the sound from your Altec Lansing Speaker System is distorted, try these solutions. First, lower the volume using the rotary dial on the control pod. Also, adjust the computer operating system volume and balance levels to the center, then fine-tune the level on the speaker. If the sound source itself is distorted, especially with WAV files, try using a different sound source like a music CD.

How to stop loud hum from Altec Lansing FX5051 subwoofer?
- R
  Robert WadeAug 26, 2025
  If you're experiencing a loud hum from the subwoofer of your Altec Lansing Speaker System, try these steps: First, unplug the AC power cord from the surge protector (if used) and plug it directly into an AC wall outlet. Then, check all cable connections to ensure they are secure. If the hum persists, try decreasing the bass level by pressing the “Bass” button on the control pod and rotating the dial to the left. Also, check the volume or bass level on your audio source device (computer, portable device, etc.) and lower it if it's set too high. Disconnecting your 3.5mm stereo cable from the audio source can help determine if the source is the issue.

Why is there a crackling sound from my Altec Lansing FX5051 Speaker System speakers?
- C
  Chelsea CastroAug 28, 2025
  If your Altec Lansing Speaker System is producing a crackling sound, start by checking all cable connections to ensure they are securely connected to the “line-out” or “audio-out” jack on your sound card or audio source, and not the “speaker-out” jack. If the connections are good, check the volume level in your computer operating system and decrease it if necessary. If the problem persists, try unplugging the stereo cable from your audio source and plugging it into the headphone jack of an alternate audio source, such as a Walkman, Discman, or FM radio.

Why is there no sound from the Altec Lansing FX5051 Speaker System subwoofer?
- J
  Jennifer CooperAug 30, 2025
  If you're not getting any sound from the subwoofer of your Altec Lansing Speaker System, first check to make sure that all cables are connected properly and are making a clear connection. If the connections are good, the issue might be that your sound source has little low-frequency content. Many .WAV and .MID files often have little low-frequency content and sound flat. Try playing a song with more bass, such as something from your CD collection.

What to do if Altec Lansing Speaker System has broken audio via USB?
- M
  Michael DunnSep 5, 2025
  If you're experiencing broken audio from your Altec Lansing speakers when connected to a computer via USB, and your computer is running Windows 98SE, the issue should resolve itself once Windows 98SE has finished the loading cycle. If that's not the issue, it's possible that your computer is running too many applications at the same time. Try quitting one or more applications until the problem is resolved, or consider increasing your computer's memory (RAM) or storage space.

Why is my monitor distorted when using Altec Lansing FX5051?
- W
  Wendy MillsSep 7, 2025
  If your monitor is distorted when using the Altec Lansing Speaker System, it's likely because the subwoofer is too close to the monitor. Because the subwoofer is not magnetically shielded, it can cause distortion if it’s too close to your monitor. Move the subwoofer so it’s at least 2 feet from your monitor.

What to do if Altec Lansing Speaker System controls do not function?
- F
  Felicia AndersonSep 10, 2025
  If your Altec Lansing Speaker System is exhibiting erratic or unexpected behavior, or if the controls aren't functioning, disconnect the AC power cord from the wall outlet, wait 20–30 seconds, and then reconnect it. This can help reset the system in case static electricity, a momentary interruption of power, or abnormal operating conditions are responsible.

Why is there a low hum from my Altec Lansing FX5051 subwoofer?
- R
  Robert ColemanSep 12, 2025
  If you notice a low hum from the subwoofer of your Altec Lansing speaker system, it may be due to the AC in your house being at 60 cycles per second, which is within the audio frequency of the subwoofer. Some low hum may be detected when your speaker system is powered on without an audio source playing, or when the volume is set at an extremely low level.
