Common Issues With Digital TV Signals

One of the most frustrating things that can happen in modern life is when something that we rely on all the time completely lets us down. Like a mobile phone when it loses its power or signal, your heating pack leaves you without any hot water, or when the picture on your TV breaks up or freezes while you are watching your favourite show. As professional Aerial installers, we can help you with the latter problem, click here. However, I am amazed at how little maintenance and thought goes into caring for the aerial system at a majority of people’s houses.

As an engineer, I have visited many homes over my time, and there are a couple of common faults that tend to crop up over and over again. Although this is not a comprehensive list, it does highlight 5 of the most common problems. A few of them you can solve on your own.

  1. Water ingress. That is where water has managed somehow to penetrate the cable, antenna or another device inside of the system like a splitter device. It usually occurs on an externally fit system and is quite common after being exposed to the weather in the UK for a few years.
  2. Broken or split coax cable. This also usually occurs due to weathering, although it can happen while work is being done to the property.
  3. Faulty amplifier. An amplifier may still be fault even when its LED light is on and working.
  4. Storm Damage. Strong winds might bring an eternally mounted aerial down in a violent storm.
  5. 4G/WiFi Interference. That can occur when a device or router using WiFi is too close to the TV.

Although that is not a complete list of problems is does make up the vast majority of reasons why we are called to come out and fix a television reception problem. As previously mentioned, a couple of the problems are ones that the homeowner can solve without need to have a technician come out.

An amplifier problem is the first one. The way that you can test for that is to redirect the cable’s aerial and use a 50p barrel join to connect one of the cables from the amp to bypass the amp. If the TV that the cable is connected to work, then you will know that likely the problem is with the amp. If not, then the problem is with the antenna. It is very easy to swap out the amplifier and you can purchase on on Amazon.

Another fix is when a nearby WiFi device is causing interference. Firesticks, Roku, etc. that directly plug into the back of a TV can disrupt a digital signal. Try turning these devices off from the power source to see if that makes any difference.

Anything other than those two faults, you will need to have a professional come out to your home to help you get your TV working properly once again.
