How to Fix TV No Signal

A "No Signal" message on your TV is almost always caused by a loose connection, an aerial issue, or a channel tuning problem rather than a TV fault.

Likely causes

• Loose or damaged aerial or HDMI cable
• Wrong input source selected on the TV
• Freeview channels need retuning
• Aerial signal too weak
• Transmitter maintenance in your area

Step-by-step fix

1. 1
   Check the input source

   Press the Source or Input button on your remote and select the correct input — HDMI 1, HDMI 2, Aerial/Freeview, etc.

2. 2
   Check all cable connections

   Ensure the aerial cable, HDMI cable, or satellite cable is firmly plugged in at both ends. Unplug and replug each cable.

3. 3
   Retune your channels

   For Freeview: go to Menu → Settings → Channels → Auto-retune. This is required when TV transmitters update their frequencies.

4. 4
   Check for transmitter issues

   Visit the Freeview website (freeview.co.uk/help) and enter your postcode to check for local transmitter issues or maintenance.

5. 5
   Try a different cable

   If using HDMI, try a different cable or a different port on the TV.

6. 6
   Check your aerial

   A damaged, poorly positioned, or weathered aerial can cause signal loss. If your neighbours have signal and you do not, your aerial may be the issue.
