indoor TV aerial<\/a> is connected to a wall, then the problem may be with the lead that connects the antenna socket to your TV. <\/p>\n\n\n\nIf your lead is of low quality, then the cable will be losing signal easily. Replace the lead or the entire aerial cable and rescan your TV for signals.<\/p>\n\n\n\n
Cables that connect your aerial and distribution equipment, such as splitters and amplifiers, could be causing the problem with your signal. Even if a professional installed your aerial, issues like poor cable termination could cause your cable to slowly degenerate at the ends.<\/p>\n\n\n\n
Fixing cable issues isn’t an easy fit. You may need to use a multimeter to test each of your cables for a short or resistance, but first, start with inspecting all terminations.<\/p>\n\n\n\nCheck whether other devices work with our TV, such as a DVD player<\/figcaption><\/figure>\n\n\n\nDo other devices work with your TV?<\/strong><\/h2>\n\n\n\nIf your TV shows the \u201cNo Signal\u201d error, ruling out a problem with your TV should be among the first things you check. <\/p>\n\n\n\n
If other devices work successfully with your TV, then it rules out your TV malfunctioning. <\/p>\n\n\n\n
Start with a device that doesn’t need an aerial, e.g. a DVD player. If you play a movie on your DVD player and the picture and sound work great, then your aerial is definitely not working.<\/p>\n\n\n\n
Test your TV\u2019s signal strength<\/strong><\/h2>\n\n\n\nYour aerial may be in good condition, but if the signal it\u2019s receiving is too weak or too strong, then the picture quality will be bad. <\/p>\n\n\n\n
You will need an aerial tester and an F-plug to gauge your aerial’s signal strength. Signal testers come in different varieties depending and are readily available in electronic shops.<\/p>\n\n\n\n
Most of these testers come with LED lights that show signal strength. This step is DIY- friendly; you don’t need any experience to use a signal tester.<\/p>\n\n\n\n
Weak Signal Strength<\/strong><\/h3>\n\n\n\nA weak digital TV signal manifests in two ways: first, you may notice distorted images on your screen or the pictures on your TV breaking. <\/p>\n\n\n\n
A weak signal could be due to something blocking your aerial from a transmitter\u2019s line of sight or that you\u2019ve connected to a transmitter that\u2019s too far away. <\/p>\n\n\n\n
To confirm whether the problem is a weak signal, use your remote to access your TV’s information panel, then check for signal strength. <\/p>\n\n\n\n
Most TVs will show your signal strength as a percentage; anything less than 75% is problematic. <\/p>\n\n\n\n
Some TVs will show you signal strength in decibels; anything less than 50dB will cause problems with your TV\u2019s picture quality.<\/p>\n\n\n\n
Fixing weak signal strength is easy; you need to figure out where the loss of signal comes from. <\/p>\n\n\n\n
First, ensure that your aerial is at an optimal height, away from distortions such as trees, tall buildings, and anything that may disrupt it from a transmitter’s line of sight. The second step is adjusting your aerial\u2019s orientation.<\/p>\n\n\n\n
Some websites help you figure out the best transmitter to receive the signal from depending on where you live. Once you find out which transmitter to point to, then direct your aerial towards it. <\/p>\n\n\n\n
You can also choose high-quality coaxial cables from the aerial to the TV to prevent attenuation or use an amplifier to boost your signal strength. <\/p>\n\n\n\n
You may even realise that your TV needs retuning or that you need to replace your current aerial with a high-gain aerial.<\/p>\n\n\n\n
If your signal strength is okay, then using an amplifier will worsen things for you. Choosing to go with an amplifier should be your last resort as they can cause signal overload.<\/p>\n\n\n\n
Signal overloading your TV<\/strong><\/h3>\n\n\n\nYour signal problem may simply be down to the fact your TV needs retuning<\/figcaption><\/figure>\n\n\n\nA signal overload happens when your TV receives too many signals. This may be because you’re using an amplifier when there’s no need for one. <\/p>\n\n\n\n
This may also occur if you’re living too close to your nearest signal transmitter. A signal overload affects TV tuners and other related equipment. This will show on a tester as flashing orange lights.<\/p>\n\n\n\n
An overloaded signal is easy to fix; if you’re using an amplifier, disconnect it and then search for the signal again. <\/p>\n\n\n\n
If not, then use an attenuator. An attenuator works by muting a TV’s signal depending on how you adjust it. <\/p>\n\n\n\n
Because it needs adjusting, you may need to adjust it lower several times before getting the correct dBs settings you need for excellent picture quality.<\/p>\n\n\n\n
You may not even need complicated devices to fix signal overload; you can try moving aerial locations to see whether that’ll solve the problem. <\/p>\n\n\n\n
Once you move locations, adjust your area in 15-degree increments and then keep restarting the booster until you get to the optimal aerial positioning. <\/p>\n\n\n\n
You can also try to move your aerial from your roof to the attic. This will at least cause a little bit of signal loss because the walls and roof tiles will act as an obstruction between your transmitter and aerial.<\/p>\n\n\n\n
What else could cause signal loss?<\/strong><\/h2>\n\n\n\nChange of weather<\/strong><\/h3>\n\n\n\nTV signals can be affected by something as small as a light downpour. Bad weather, such as when it’s cloudy, could also distort your TV’s signal because they interrupt the communication between your TV and transmitter or satellite. <\/p>\n\n\n\n
Before you blame your signal loss on your aerial, wait for any overcast to clear up.<\/p>\n\n\n\n
Faulty TV<\/strong><\/h3>\n\n\n\nSo you’ve checked all connections, ruled out every possible aerial problem, and your TV still won’t show pictures? <\/p>\n\n\n\n
Your TV may be the problem. If you can find another TV to test out this theory, swap the TVs, and if the new one can pick up signals just fine, then you’ve found your culprit. <\/p>\n\n\n\n
Even new TVs out of the box can be faulty. Look out for cracked screens, or find a TV technician to look at your TV.<\/p>\n\n\n\nAlways check you haven’t simply pressed the wrong settings on your TV<\/figcaption><\/figure>\n\n\n\nWrong TV settings<\/strong><\/h3>\n\n\n\nYou can accidentally change your TV settings by pressing the wrong button on your remote. You will get the “No signal” error when you choose the wrong input despite the aerial working correctly. <\/p>\n\n\n\n
This doesn’t mean that you have no signal; you’ve just selected a signal that doesn’t match the source input. The best way to fix this is to find the settings that revert you to the original input settings.<\/p>\n\n\n\n
You should start with \u201cinput” or “source” and pick “AV”, then browse through AV options.<\/p>\n\n\n\n
A standard TV will either have the TV or DTV option. Choosing either will help your TV get the signals from your aerial. If both options are available, go for “DTV”. <\/p>\n\n\n\n
Once you pick the correct settings, retune your settings, or rescan your TV to access your favourite channels.<\/p>\n\n\n\n
