Spectrum TV

I am having audio problems with my cable service.

If you have picture but no sound:

  1. Press Volume Up Button to check that the volume is at a high enough level.
  2. Check all wires to ensure they are firmly connected, including any coaxial cable.
  3. Ensure that the audio and video cables are connected to the same inputs on the TV.
  4. If available, try replacing the audio cables with a different set. If this resolves the problem, the cables are bad and need to be replaced.
  5. If the issue remains, reboot your Spectrum Receiver by unplugging the power cord for 5 to 10 seconds and then plugging it back in.
  6. When the time is displayed on the front of the Spectrum Receiver, turn it back on.

If you still have no audio, Contact Us for additional assistance.

If you are hearing sounds such as buzzing, static, or humming:

It can help to raise the volume of the Spectrum Receiver as high as possible so that your speakers can be kept as low as possible. This can reduce excess noise.

  1. On your remote control, press Volume Down Button to turn the TV's volume all the way down.
  2. On the Spectrum Receiver, press Vol+ to turn the Spectrum Receiver's volume all the way up.
  3. On your remote control, press Volume Up Button until the volume is at the level you want.
  4. If the issue remains, Contact Us for additional assistance.

If your audio has an echo or seems out of sync with the video:

  1. Check a different channel. If it is limited to one channel, it is likely a temporary problem with the broadcaster.
  2. If the issue remains for an extended time or if it exists on multiple channels, reboot your Spectrum Receiver by removing the power cord for 5 to 10 seconds and then plugging it back in.
  3. When the time returns to the front display on the Spectrum Receiver, turn it on.
  4. If this does not resolve the issue, Contact Us for additional assistance.

To ensure that all devices are receiving power:

  1. Power the TV and Spectrum Receiver on and off.
  2. If they do not have any power, check that the power cables for all of your devices are securely connected, including the Spectrum Receiver, TV, and any VCRs or DVD players.
  3. If the power outlet is controlled by a wall switch, make sure the switch is in the On position.
  4. Plug a lamp or some other device that you know works into the power outlet for your TV. If it does not work, there may be a local electrical problem such as a power outage, a damaged wall outlet, or a tripped circuit breaker.
    • For electrical problems, contact your local electric company or a qualified electrician.

If your devices are receiving power but you still have no picture, no sound, or the "No Signal" message:

  1. Ensure that all wires are securely connected, including the coaxial cable and any audio and video cables.
  2. If you have moved your Spectrum Receiver to another location, move it back to the original installation outlet. Keep in mind that cable services are set up to work on the outlet that they were originally installed on.
  3. Ensure the TV is tuned to the proper input for your connection method. For example:
    • If you are connecting with only coaxial cable, the TV or VCR may need to be set to channel 3 or 4.
    • If you are using video cables such as HDMI or component cables, your TV must be tuned to an input such as Video 1 or HDMI.
  4. Reboot your Spectrum Receiver by unplugging the power cord for 5 to 10 seconds and then plugging it back in.
  5. When the time is displayed on the front of the Spectrum Receiver, turn it back on.
  6. If the issue remains, log on to My Services and perform an equipment refresh on your Spectrum Receiver. See How do I refresh my modem or Spectrum Receiver online?

Another possibility is there is a service disruption in your area. To find out, see How can I find out whether there is an outage in my area?

For information on changing your Spectrum Receiver to detect HDMI connections, see I installed HDMI cables. Are there any settings I should change?

If there is no reported service disruption and you still have no picture or audio, Contact Us for additional assistance.
