The last thing you want to do is to spend endless hours fiddling with the aerial and your TV settings without knowing what you are doing, and we are here to help you with this. In this article, we are going to tell you exactly how you can check if your aerial is working, and what you can try to do to fix it. 

If you are experiencing problems with either your TV or your aerial, you can follow the methods below to find out what is causing the problem. There are lots of things that could have gone wrong, so there are plenty of things to try. Hopefully, you will be back to watching live TV in no time at all.

How to Check if Your TV Aerial is Working

There are lots of different things that you can do to check if your aerial is working, and we are going to explain some of these things here for you. You can go through all of these methods to try and figure out what the problem is.

Some of these are more simple than others, but it is best to work through them methodically to eliminate certain causes and get closer to finding out what is causing the problem.

Test Your TV Aerial Cable 

The first thing that you should try to do is test your TV aerial cable, and this is one of the best ways to find out if it is the aerial or the TV that is having issues.

The best way to do this would be to connect everything up to a different TV. If you have another TV in your home, test this method out to see if it works. If everything is working fine, then the TV is the problem, but if it still isn’t working, then it is, in fact, the aerial that is the problem.

Another way to check the TV aerial would be to take the TV that you know is working as it should and test it. If the TV is able to get a signal and bring up all of the channels, then your TV is totally fine.

Even though your TV might be alright, it is likely that you have a problem with your aerial, and you will need to find out what is causing it in order to get it working again.

Test Your TV Signal

The next thing that you should do is test the TV signal. This method is slightly more complicated than the previous one, but you just need to get yourself an aerial tester to get started.

You can use an aerial tester to test the signal of the aerial. You can buy these in a variety of electronic stores, or simply order one online, and once you have your hands on one, you can start the test.

More often than not, these testers will have LED lights on them that will show you the strength of the signal. You will not need any special knowledge or training to use these testers, but you will need an F-plug, as this is usually the connection that is needed.

Low & Weak TV Signal

If you have a weak digital TV signal, you will be able to tell. The quality of the picture will start to break up, and there will likely be some image distortion on the screen. You may also experience muted sounds and other issues.

All of these things are telling you that you have a weak signal or there is something interrupting the signal. 

However, to confirm that you have a weak signal, you can have a look at your configuration settings. You can also go to the signal strength panel  to find out. Sometimes, there may be a signal message on the screen, which might even be displayed as a percentage.

The lower the percentage, the worse the signal is. Other TV’s might show this signal strength in dB, and anything less than 45 dB can cause some issues.

You should try and find out what is causing this weak TV aerial signal, as you might be able to improve it by doing things like switching cables, aligning your aerial, or something else.

You can also get your hands on a TV amplifier, which will work to boost your signal strength. However, you should be mindful of signal overload, which can cause another problem.

Signal Overload

As you might have already guessed, a signal overload will occur when the TV has received too much signal. This can then overload the TV tuners or other equipment, and cause more issues. The problems that occur from too little signal are the same that occur when you have too much signal.

What to Do if There is No Picture On Your Screen 

The first thing you should do if there is no picture on your screen is check that the aerial is still connected. This might sound like an obvious thing to check, but it is worth double-checking to make sure that it hasn’t come loose. 

One of the most commonly found issues when it came to TV aerials not working was that the aerial had simply been disconnected. This is really easy to do, and you might not have even noticed.

So, before you go ahead and panic, make sure to check the cable. To do this, all you need to do is look behind the TV and make sure that the cable is plugged in. If not, located the cable and put it back to its rightful place.

As well as this, you might want to make sure that the cable is not damaged or broken. If you do find any signs of damage in the cable, then it might need to be replaced as this could be what is causing the problem.

Another thing that you should check is that the TV is on the right source or input, as if it is not, there will likely be no picture on your screen.

This is another common problem, and it might even pop up with a signal message, even though this is not the case. If this message pops up, it doesn’t necessarily mean that you have no signal, and it could just mean that you are on the wrong input. 

To fix this issue, you will need to find the button on the remote control or the TV that will switch the input that you are connected to. This is typically called source, input, or AV.

Once you have found this button, press it to find a list of all the inputs on the TV. There may be a few of them, but the one you need will be called TV or DTV. Select this method and your picture should come back on.
