Imagine this; You’re settled on the couch, ready for your favorite weekly TV show and you’re met with the dreaded “no signal” message. It’s easy to think it’s a mistake. However, this does not necessarily mean that there is something wrong with the TV, but rather something to do with the signal it is receiving. It can be very frustrating because we rely on our televisions for comfort and companionship.
While it can be corrected through support and troubleshooting, you may wonder what causes the TV to lose signal in the first place. In this article we will explain some of the reasons why TVs lose signal.
Weak signal strength
If there is a weak signal in your area, it can significantly affect the TV’s ability to tune in and receive the signal. A weak signal can be caused by a general distance from a transmitter or physical obstacles. You can find your distance from your broadcaster by visiting the Freeview website here.
Channel updates
Occasionally Freeview will update their channel list. On these occasions, they usually inform TV users on the specific channels to say when the channels will change and what to do for the day. When these channels change, it usually means that the TV needs to be re-tuned to update the channel list and any changes that have occurred.
Weather conditions
Bad weather conditions, such as strong wind and rain, can also negatively affect the signal on your TV. This is because the weather can physically interfere with the signal and move the air. However, it is not only bad weather conditions that affect the air, but warmer weather can also have an impact. This is because warm weather can produce high pressure in the air, which means it requires the television signals to travel further.
Air setup
Aerial setup can also cause signal problems. This refers to the way an antenna is physically placed. If you use an external antenna, you will not be able to notice any physical movements. However, when using an internal antenna, such as a portable antenna, knocks or bumps on the antenna can change position and affect the signal. We recommend moving the air to more open spaces, such as windows, to receive the signal without physical interference.
Electrical disturbances
Too many electrical devices nearby can affect the signal. This is because other devices, such as microwaves, transit waves as part of their processes. If the TV is between several devices transmitting and receiving signals, it can sometimes block the signal. We recommend making sure the TV has enough clearance from other devices.
TV is not receiving a signal from a connected device
If you watch TV through an external set-top box or streaming stick, the message may appear when the box is turned off. This can be corrected by turning off the box. Similarly, if the TV has changed the source, you may need to switch to the correct HDMI input to recover the output.
conclusion
There are many different reasons why your TV may lose signal, and by understanding these, it can assure you that the issue can be resolved. If in doubt, we recommend you consult your user manual for tips on how to get your signal back.
