FAQs

This message will show when the TV is not receiving a signal, either through the aerial or an external device connected.

Ensure you have selected the correct input source for viewing (for example, HDMI if you have an external device connected to the TV via HDMI). If you are using an aerial to watch the inbuilt Freeview channels, change the input source to Digital or DTV to view these channels.

If you have purchased a universal remote, it should come with an instruction guide as to how to pair the remote with the TV. It will often have a list of codes for different brands. Locate the codes for this brand of TV, and follow the instructions to pair together.

Check that all connections are fully inserted on both your TV and viewing source (for example, an aerial or a Sky box). If the issue persists, please try the following.

  1. Unplug the TV from the wall and disconnect any external devices.
  2. Hold down the manual button on the unit for 30 seconds (if unsure of location please refer to the user manual).
  3. Plug the TV back into a mains socket.

Please see how to perform a power reset here: 

If the TV is missing some channels, we would recommend carrying out an automatic channel scan to tune in these channels, and if necessary trying a First Time Installation or Factory Reset through the menu.

If this has not resolved the issue, you can check for any issues with the signal in your area using the Freeview website here.

You can use a digital aerial on this TV to access Freeview channels. This can be an external aerial that has been fitted by an engineer, or an indoor aerial that you can purchase and fit yourself.

If purchasing an indoor aerial, we would recommend checking the distance from the transmitter as aerials will have a different range specified on the product box. You can check the distance from your nearest transmitter using the Freeview coverage checker here.

This should help to identify what aerial you will need, and what distance range would be required for your location.

Ensure the TV is plugged into a mains socket and, if necessary, try an alternative mains socket. An extension lead does not always supply the TV with sufficient power, so the TV may not be able to turn on fully if connected this way.

We would recommend trying the below steps:

  1. Unplug the TV from the wall and disconnect any external devices.
  2. Hold down the manual button on the unit for 30 seconds (if unsure of location please refer to the user manual).
  3. Plug the TV back into a mains socket.

Please see how to perform a power reset here: 


If the unit has no power, try the following: 

  • Check that the unit is not in standby by giving the power button/on/off button a quick press. 
  • Try an alternative mains plug socket. 
  • Change the fuse in the plug.

If you are unable to resolve the issue, please contact the support team using the details on this page. 

Note: This is only applicable to sound bars with Bluetooth. 

If the unit will not pair with a Bluetooth device, try the following: 

  • Ensure you have selected Bluetooth mode on the soundbar. 
  • Try disconnecting and reconnecting via Bluetooth. 
  • Unplug the unit from the wall, hold down the power button for 10-15 seconds, plug back in, and try again. 
  • Ensure the device you are trying to connect to can send sound. If you are trying to connect with another speaker this will not work as the soundbar can only receive the sound, and cannot send sound.

If you are unable to resolve the issue, please contact the support team using the details on this page. 

If there is distorted sound, try the following: 

  • Adjust the volume to the preferred level. 
  • Increase the volume on the device connected to the soundbar. 
  • Ensure you have the correct mode selected. For example, Bluetooth. 
  • Ensure any cables are securely fitted. 
  • Ensure there are no audio devices nearby which may be disrupting the signal.

If you are unable to resolve the issue, please contact the support team using the details on this page. 

If the remote does not work, try the following: 

  • Check that the unit is not in standby by giving the power button/on/off button a quick press. 
  • Change the batteries in the remote. 
  • Unplug the unit from the wall, hold down the power button for 10-15 seconds, plug back in, and try again. 
  • Try a camera test on the remote to check for the infrared signal. Put your smartphone in selfie mode, point the remote at the camera, and press some buttons. If the remote is working you should see a flicker at the end of the remote. If there is no light, it would indicate the remote is not producing a signal.

If you are unable to resolve the issue, please contact the support team using the details on this page. 

If there is no sound, try the following based upon the connection used. Please note, not all connections may be available on your model so check the user manual for the available connections. 

THERE IS NO SOUND VIA AUX CONNECTION.

  • Adjust the volume to the preferred level. 
  • Increase the volume on the device connected to the soundbar. 
  • Ensure you have selected AUX mode on the soundbar. 
  • Turn on headphone volume on the connected device. If a TV, this is usually found within the sound menu. 
  • Disconnect and reconnect the AUX cable. 
  • Unplug the unit from the wall, hold down the power button for 10-15 seconds, plug back in, and try again.

THERE IS NO SOUND VIA BLUETOOTH.

  • Adjust the volume to the preferred level. 
  • Increase the volume on the device connected to the soundbar. 
  • Ensure you have selected Bluetooth mode on the soundbar. 
  • Try disconnecting and reconnecting via Bluetooth. 
  • Unplug the unit from the wall, hold down the power button for 10-15 seconds, plug back in, and try again.

THERE IS NO SOUND VIA OPTICAL.

  • Adjust the volume to the preferred level. 
  • Increase the volume on the device connected to the soundbar. 
  • Ensure you have selected Optical mode on the soundbar. 
  • Disconnect and reconnect the Optical cable. 
  • Change the TV’s sound setting to match the external speaker connected. For example, you may have an option for PCM (pulse-code modulation) which you can set. This is necessary to ensure the audio format matches that of the sound bar you have connected.
