KEY TAKEAWAYS:
Most TV owners don’t know that when using an over-the-air antenna, it’s essential to re-scan your TV channels often. Additionally, if you have to repair or replace your antenna, like when you replace TV ear tips, you should re-scan as well. However, in some rare cases, TV owners have lost their channels after re-scanning.

Are you wondering why your digital TV channels disappear? Don’t panic. In this post, we will help you understand why your TV loses channels.
There are three main reasons why your TV could be losing channels:
If you have correctly installed your antennae as outlined in your owner’s manual and set the TV input to “Antennae” to run a channel scan, then you should be able to view at least a few of your local digital channels. If this is not the case, your problem could be due to the following:
Depending on your location, buildings, hills, or trees could come between your TV broadcast tower and the antennae, blocking the signal. If you have an indoor model like the best indoor antenna, try moving it around your home. To fix this issue for an outdoor model, elevate your TV antennae or use a taller mast.
It’s normal that the digital signals for the channels you have lost were stronger when you initially scanned than it is currently. There are several reasons why this could happen, including weather conditions, electrical interference, weak signal, and atmospheric pressure.
Alternatively, if you live in a rural area, we suggest you consider the best TV antenna for rural areas, so you still get all of the channels you need.
Carefully check your Digital TV coaxial cable for wear, corrosion, or loose cable fittings. Avoid using a splitter, it could weaken the signal strength causing the channels to disappear. Instead, disconnect the connection from the splitter and run the cable straight from the cable box. Loose cables are another reason you keep asking, “Why does my TV flicker every time?” Additionally, this can cause your TV screen to turn green from interference. If this happens, you can read about why your TV screen is green for some troubleshooting tips.
If your TV coaxial cable length is too long (over 100 feet), more than 1/3 of the digital transmission signal could be lost. If you need a longer cable, you’ll need to install a pre-amplifier.
Insider Tip
An outdated TV channel could cause your channels to disappear, especially if you use an older model TV. First, visit your TV manufacturer’s website and check for updates. You could also contact your manufacturer to find out if your specific TV model needs a recent update. Then, rescan your TV after the update. This may also be a sign of why a curved Tv may be a better option for you.
It rarely happens, but your channels may be disappearing due to a faulty digital tuner. It’s possible to have a damaged tuner on a new TV out of the box. To check if you have a faulty digital tuner, install the antennae and cable on a separate TV.
