From its earliest days, TV has evolved quite a bit. From the small screen in a wooden cabinet to the modern, large, flat screens of today, the technology in the TVs themselves has advanced to give us perfect, high-definition pictures.

The broadcast signal itself has also advanced, moving from the long-used analogue signal to the digital broadcasts, helping to ensure a better and clearer picture.

The Guardian recently discussed the changeover just after the final switchover in an interesting piece.

How to access digital TV

You can access digital signals via cable or satellite services or by the free-to-use Freeview service.

To access Freeview, you will require an appropriate aerial that is correctly installed, but you should be able to find a local company to sort this out for you if you are unable to fit it yourself. For example, if you were looking for a company that handles Bristol Aerial installations, you could consider http://aerial-installations-bristol.co.uk/.

Reception issues?

We know digital signals should provide a better, clearer picture for viewers, but what happens when your reception lets you down?

There are a number of issues that are easily fixed that could be causing your reception issues.

Freeview

Pictures breaking up and poor sound are common problems. To fix them, start by switching off your box and checking that all the leads in and out of your box are correct.

If it’s intermittent, consider whether electrical interference could be an issue and try switching other electrical equipment on and off to see if this is the cause.

If you have never had a good signal, you may need to have your aerial adjusted or re-aligned.

A green screen can be caused by a loose scart lead, so check your cables and connections and even the TV itself.

If channels move or disappear, consider getting a full re-tune for your box.

Satellite

Pictures breaking up could be due to the weather. Strong winds and rain can affect the dish, so wait and see if things improve with the weather.

Always consider a reset. If this doesn’t solve it, you may need to have your dish checked by an engineer.

Cable

Always check all connections and cables, and then consider a reboot to see if that helps. If not, an engineer check may be required.
