There are multiple reasons why a TV aerial may stop working, many of which come under the generic “no signal” label. Without identifying the cause, it can be difficult to organise repairs.
1. Positioning
The location and direction of your aerial both have a significant impact on signal quality. Hills, trees or construction work can all act as obstructions. Try to ensure your aerial is at the highest point possible and turn it to face the closest transmission tower.
2. Equipment
Older equipment is particularly prone to breakdowns and is harder to fix. You may need to adjust things manually, rather than hoping for automatic digital updates. Unnecessary or badly-installed signal amplifiers can also cause problems.
Regularly check every part of your equipment, from cables to aerial, for damage. For inaccessible rooftop aerials, a professional service such as https://steveunettaerials.co.uk/tv-aerial-repair-near-me/cheltenham/ that offers TV aerial repair Cheltenham may be able to help.
3. Interference
Potential sources of signal interference include mobile phone stations, local building work or nearby electronic devices. Bad weather such as high winds, heavy rain or extreme ice and snow can both interfere with the reception and physically damage the aerial.
4. Connection Issues
Even if you have the most high-tech modern equipment, it will not work effectively with loose connections. Cables can easily be knocked out of place or damaged over time without your realising.
5. TV Source
Modern televisions often have different sources such as AV, DVD or HDMI. This allows you to switch between your television and any external boxes, laptops or other connected devices, usually by via remote control. If you are in the wrong source mode, you will not be able to watch.
6. Tuning
Televisions periodically need retuning, whether because the channels have been updated or you have physically repositioned your TV set. You can usually retune from your settings menu.
When your aerial stops working, there are a few things you should do to first identify the issue, then decide the best course of action to restore your television.
