Common Problems with Digital TV Signals

There are few things more frustrating to occur in our modern life than when we find that the thing we rely on so frequently lets us down. Such as a mobile phone if it loses its signal or power, the heating packs in leaving you with no hot water, or when the TV picture breaks up and freezes during your favourite show. As Aerial installers Crewe it is the latter problem that we can help with. However, it amazes me how little thought and maintenance goes into looking after the aerial system in most peoples homes.

Having visited plenty of homes in my time as an engineer, there are a few very common faults that crop up again and again. Although this isn’t an exhaustive list it is just to highlight 5 of the most common, a few of which can be rectified yourself.

  1. Water ingress. This is where water has somehow managed to penetrate the antenna, cable or any other device within the system such as a splitter device. Usually happens on externally fitted systems and is very common after a few years of being exposed to the British weather
  2. Split or broken coax cable. Again, usually due to weathering, though it can occur during building work being done on the property.
  3. Faulty amplifier. Even when the led light is working with the amp, it can still be faulty.
  4. Storm Damage. After a violent storm, and externally mounted aerial can be brought down by strong winds.
  5. 4G/WiFi Interference. This can happen when the router or another device that uses WiFi is positioned too close to the telly.

Although this isn’t a complete list of faults it does make up a vast majority of why we get called out to fix a problem with the television reception. As previously mentioned there are a few of these problems that can be rectified by the home owner without going having the cost of a technician visit their home.

The first is an amplifier problem. The way to test this out is to redirect the aerial in cable and with a 50p barrel join, connect it to one of the cables coming out of the amp, thereby bypassing the amp. If the telly that the cable is connecting to works, then you will know that the amp is likely to be the problem. If it doesn’t then it points to the antenna instead. An amplifier swap is a piece of cake to do and it can also be bought from amazon.

The second fix is when there is interference from a nearby WiFi device. Roku, firesticks etc that plug directly into the back of a television will disrupt a digital signal, so try turning off these devices from their power source to see if it make a difference.

Apart from the two faults mentioned anything else will require the visit from a professional to help you get your television working properly again.
