Your cables may be loose. If you have loose cables, you’ll most likely get no signal or a spotty signal. So make sure your connections are tight at your TV and your antenna. While you’re checking your connections, also take a look at your cables to make sure they aren’t bent, looped, or otherwise broken.
Why won’t my TV aerial pick up any channels?
First check that your TV is set to the correct Source or Input, try changing the Source or Input to AV, TV, Digital TV or DTV if you haven’t already. If your “No Signal” message is not due to incorrect Source or Input being selected, then it’s most likely caused by a set up or antenna fault.
How do you check if a TV aerial is working?
Test Your TV Aerial Cable Another way to check the TV aerial is to take the TV to a socket that you are sure is working correctly and perform a test. If the TV can get a signal and identify the channels on another socket, you can rest assured that your TV is fine.
Why is my TV not searching for channels?
One of the most common reasons why TVs are not able to find channels is because there is a problem with their cable boxes. Restarting your cable box could clear it of any glitches that are stopping it from working as it should.
