Why Did My Broadcast TV Channels Disappear?

A very common question I get on DisableMyCable.com is "why did some of my broadcast TV channels disappear?" Usually, people think something is wrong with their antenna, but TV antennas are pretty simple devices, just a piece of metal basically (unless it is amplified). Usually, the antenna isn't broken and it's some other issue.

1. The TV Station's Frequency Changed During the FCC "Re-Pack". Here's What to Do.

The most likely culprit for losing a channel in 2020's FCC "re-pack" is that the channel's broadcast frequency changed.

If you suddenly lose a channel, the first thing to try is to re-scan for channels on your TV. 

If that doesn't work, unplug your antenna, re-scan, then plug your antenna back in and scan again. Sometimes that helps clear your TV's memory so it can acquire the new channel.

If the channel is still not showing up, and you have an older TV (like my Sony Bravia from 2008), you might have to tune using the station's real RF channel. On modern TVs, you won't need to do this, but my old Sony doesn't support how to map displayed channels to real channels.

To find the station's real physical channel, go to the Station Finder and click the button to launch it. Enter your zip code. When you see the results, find your station's call sign. If you see an "R" next to it, it means the channel was "re-packed" and the frequency has changed.

Click the station's call letters so that it expands and you can find the real channel there:

Once you've found your station's actual RF channel, try tuning to that channel instead of the station's regular channel. Note, you will have to add a decimal point and a digit to it, often .1 or .3. In my case, even though the website said channel 31, I had to tune to 31.1. And voila! I was able to get my local CBS channel!

If this works for you, you have a couple more options. Try tuning into the station's original channel number. Your TV might recognize it now as the new channel.

If that doesn't work, then check your TV manufacturer's website for a firmware upgrade for your TV. This might allow it to recognize virtual channels.

If these don't work, then you'll just have to use the new channel number instead of the original one. That is my situation with my 2008 Sony Bravia. Kind of a pain, but I'm happy that I've got that channel back!

2. The TV Transmitter Tower Changed Location

In the FCC re-pack, some transmitters might move temporarily to an auxiliary tower while the main tower is upgraded. So, try to orient your antenna in different directions to find it. Enter your zip code into the Station Finder and click your station's call letters to determine which direction the signal is coming from.

3. The TV Transmitter Power Was Temporarily Reduced

During the FCC re-pack, a TV station might temporarily use a lower power transmitter while they upgrade their equipment. To see if your TV station is temporarily transmitting on lower power, type in your TV's call letters below to see your station's FCC report, for example, "KCBS":

If you see the words, "Special Temporary Authority" in the report in red, it means your station is temporarily operating at reduced power. You can also email or call your station to confirm (usually their contact information is on their website).

If re-scanning doesn't solve the problem, try my tips to improve reception.

Another possibility is that the TV transmitter had a technical difficulty resulting in reduced power. Try emailing the station to find out why the station went away. Reader Eric did this and they responded:

One of our transmitters experienced a power surge and needs a part replaced. We ordered one and will replace it as soon as we get it!

4. The TV Station Went Away

Sometimes TV stations go away completely. This happened to a few stations here in Los Angeles, where the FCC allowed TV stations to auction off their spectrum to wireless providers. Usually, these are higher-numbered not-as popular stations as opposed to the major networks. Google the station's call letters to see if you can find out what happened. Unfortunately, there's not much you can do about this.

5. Your Antenna Moved - Try Re-Orienting It

From my testing, I've found that even a small change in antenna position or angle can have a big impact on your reception. Try moving your antenna around to see if that helps.

If your antenna is on your roof, you might have to go up there to make sure it hasn't fallen or shifted.

6. Your Antenna's Amplifier Went Bad - Try Bypassing It

An antenna is a dead-simple device, it's pretty much a piece of shaped metal. But, an antenna amplifier is a much more complex device, and it's much more prone to failure.

If you have an amplified antenna (i.e, your antenna requires power), such as the Mohu Leaf 50, try removing the amplifier from your antenna and plugging your antenna directly into your TV. This worked for reader Faith G!

7. Your Cables are Loose - Reconnect and Tighten Them

Make sure your coax cable connections are tight, both at your TV and at your antenna. I was advising one reader offline, and this turned out to be his problem! He was losing signal at the same time every day. He disconnected all of his cables to his attic amplifiers, then re-connected them. Problem solved!

8. Electronic Interference - Turn off Other Devices

It is possible that a new electronic device in your home or neighborhood is wreaking havoc on your TV signal. I've heard all kinds of stories about this from my readers.

First, turn off all electronic appliances in your home and see if your reception gets better. This includes fluorescent lights, computers, Wi-Fi routers, cable modems, Bluetooth devices, cell phones, and so on. If your reception improves, turn on each device one-by-one until you find the culprit.

Some users have reported TV interference when their Amazon Fire TV Stick is plugged in. Try unplugging it. If the signal improves, use the HDMI extender cable that came with your Stick and move it around until it goes away. One user wrapped the Stick in aluminum foil to get rid of the interference.

If you live in a condo or apartment complex, it's possible that a neighbor's device is causing the problem. Not much you can do about that, but you can try my tips to improve your antenna's reception.

9. Atmospheric Conditions, "Tropospheric Ducting"

The weather and time of day can adversely affect your TV reception. Clouds, fog, rain, etc. can adversely affect your signal. Some people report worse reception at night while others report the opposite.

"Tropospheric Ducting" is when TV signals bounce back down to the Earth from the troposphere (the lowest layer of the atmosphere) and travel much further than usual. Isn't that a good thing though? Actually, no, because you can get far-away TV signals interfering with your local stations. The only solution is to wait it out. It usually ends in a matter of hours.

Try these tips to improve your reception.

10. Your TV's Tuner is Going Bad

This is less likely than the other items on this list, but it's possible that your TV's tuner circuitry is degrading. I have heard of this from a couple of my readers. If you have another TV, try tuning the missing stations on that one as an experiment.

If your TV's tuner is going bad, you can purchase an external tuner, or even better, a DVR. But, I wouldn't purchase anything until I confirmed for sure that my tuner was bad.

11. There Is a New Physical Obstacle

If they just built a high rise between your home and the TV transmitter, it could be blocking the TV signal. This could happen, especially in big cities like New York. Try playing with your antenna position.

Conclusion

These are some of the reasons why your favorite station might have gone away. Let me know if any of these tips have helped or if you found any other causes for the loss of TV stations. - Brian

Your broadcasting is a joke . It good in the day time but later in the evening it weakens then its lost . If you can't keep up with your signal you should shut yourself down .

There is a group supported by tech help that have been actively encroaching tv broadcasts for their own profit.They have at will taken my channels to broadcast music and I have seen some videos. The are relentless and I am sure will in time invade free broadcasting for their own profit. These individuals are unlicensed broadcasters. I have been dealing with them for years.I have contacted the FCC. I don't think there going to do any thing.

My old Vizio is dropping off channels. First it was 13.1 while other 13 channels remained After doing a full channel scan 11.1 disappeared. 11.4 is still there. I have done all of the Vizio troubleshooting procedures and still nothing.

Hi Elliott,

It's probably not a problem with the TV but with the TV channels in your area. Check the Station Finder to see what channels are truly available in your area:

I lost all of my free tv channels April 1, 2021. I had turned off Spectrum internet due to gojng into the hospital for an extended stay. When I resumed oaying for internet, one by one, I started having issues such as not being able to use my laptop on wifi and my digital free channels on mysmart t.v. at the same time. I feel SPECTRUM definitely blocked my digital signals. I have tried 4 tv sets, 3 antennas, NO DICE. NO TV. Spectrum denies culpability and also forced me to rent their router/modem saying my personal owned one was no longer supported...I am on SSI an cannoy afdord $45 a month for tv and get very limited channels through Wi-Fi. Please help?
