Why do I need to retune my TV?

Retuning your Thorn TV does not need to be done in excess, however, completing a rescan every once in a while on your TV has multiple benefits. For example, a retune will update your program list and remove any channels that are no longer available or add new programs that may have changed frequencies.

Benefit 1. Updated channel list

A retune on your Thorn TV will update your current program list. New channels will be added, any programs that have changed frequencies will be updated.

If a channel has stopped broadcasting, it will be removed.  A retune is most important if you have moved locations, as this will update what is available to you.

Benefit 2. Improved signal

Running a retune on your Thorn TV will refresh your aerial’s signal and improve the quality of your display.

An improved signal will allow your television to potentially pick up more channels, with ones being a bit further away.

After a retune has been completed on your Thorn TV, the clarity of the images displayed on your screen will be improved.

How to tell if your TV is going out

If you find that you are needing to retune your Thorn TV almost too frequently because your channels keep disappearing, your display is constantly pixelated or unclear, this may be a sign that your smart TV is starting to obtain internal hardware issues, and it may be time for it to be replaced.

Reason 1. Audio issues

If you experience sound issues when you are trying to watch something on your Thorn TV, this is a clear indication that there may be an underlying issue with your device.

Your audio should be clear. If you have no sound at all, or it keeps disappearing or sounding faint, there could be a problem with your speaker on the internal hardware.

Reason 2. Fuzzy screen

Your image could be fuzzy and unclear.

Other screen issues along with the fuzziness include the picture being dottier, without being in focus.

Sometimes, this can be caused by ‘dead pixels’ on your TV screen. This issue can unfortunately not be rectified on its own, and your TV would need to go in for repairs.

Occasionally a pixelated image will appear only on a certain type of media that is being used (eg; a DVD), so try something else and see if the pixels disappear.

Reason 3. Colour change

Your Thorn TV could be producing the incorrect colours, or the colour contrast has become very weak.

If a picture should be a certain colour, and it’s coming up different, this will be a sign that there is an issue with your TV’s image display.

A fading screen will also indicate your TV is possibly breaking down as well as lines and bars showing up across your display.

Tip, going into your display settings and changing the brightness and contrast setting may help with this problem.

Reason 4. Frequent loss of channels

If you are constantly losing channels off of your program list, or they keep changing frequencies, then you are most likely having problems with your TV’s signal.

You should not have to retune your Thorn TV more than 3 times a year.
