Do you hear crackling from your television? You may notice a crackling noise when watching any program on your tv, while changing a channel or when your tv is shut down. This noise can be very annoying as it can distract you from enjoying your favorite tv show or program.
The crackling noise from your television is normal and it’s usually due to temperature variations. You don’t need to panic when you hear this noise as it is completely harmless. However, this noise can become worse if ignored.
Some of the simplest and quickest ways to get rid of the crackling noise in your TV include; adjusting the settings of your TV, updating your TV to its latest version, cleaning up in-built speakers in your TV, and properly mounting your TV on the wall.
Possible Cause of the Crackling Noise in Your TV
Before we move on to the fixes, let’s figure out some reasons why your TV makes a crackling noise.
- Dirt collected over your speaker
- Incorrect replacement of your television
- Damaged ports and other peripherals
- Outdated television software
- A noisy tv channel
- Overheating your television
- Improper tv sound settings
How to Fix the Crackling Noise in Your TV
Properly Mount Your Television on the Wall
Your tv can induce crackling noise if it’s wrongly mounted on the wall. If your tv is tilted, with the speakers facing the wall the sound will probably bounce off the wall and distort the sound. The best line of action is to mount your television forward so that the speakers will face the room.

Clean Up the In-Built Speakers in Your TV
Sometimes dust may accumulate on your speaker grills hence causing a crackling noise. Clean up your speaker grill with a soft cloth to take out the dust and debris. If there is an air conditioner installed directly above your television wall it can also cause noise. Sometimes an air conditioner can leak water on your wall and cause damping. The damping can badly affect your television speakers and distort the sound produced. To remedy this problem you need to change the position of the TV in the room if that’s the case.
Maintain Proper Airflow Around Your TV in the Room
It is common for electric components inside your television to heat up after long periods of usage. However, these components tend to expand when the temperature of your room is high or rising. This is possibly the reason why you hear a crackling noise when your TV is shut off, as a result of the contraction of the components from the expansion due to a decrease in temperature.
For instance, if you are a motorbike rider you might have noticed a tic-tic and crackling noise from the exhaust pipe when off the engine. This is the same case as your television.
To get rid of the problem, you need to give your TV a rest in-between watching. Make sure there is proper airflow around the TV in your room. Also, make sure there is no heating equipment such as a heater in your room placed very close to your TV or facing it. You can also clean up the air vent properly as it might be blocked by dust and debris to promote proper airflow.
Try Changing Your TV Channels
One way to fix the crackling noise in your TV is to change the channel. Sometimes the channel you’re watching may create crackling itself and you might misinterpret that as a problem with the TV. Likewise, the volume of your TV may be too high hence creating a distorted and crackling noise.
To get rid of the crackling noise, simply change the channel and see if the noise persists. However, you can also mute your TV to find out if the TV channel is the culprit. Also, try lowering the volume of your television to see if the noise stops.
Check Out the Ports, Cables, and Peripherals
The cables connected to your television may wear out over time. When this happens the signals do not pass through the cables properly due to the breakage or wear out. If this is the case then you need to consider replacing the broken or worn-out cables.
Likewise, foreign substances and dust can get attached to your television ports and prevent the connector from properly connecting to your TV. To mitigate this issue, simply clean up the ports with earbuds to remove any dust collected over there.
However, the external speakers connected to your television can also be the cause of the noise. You can also swap external speakers with other speakers to see if the noise stops.
Adjust the Settings of Your Television
Most smart televisions have sound modes to improve their hearing quality. However, if your TV is making crackling then it’s likely the mode set for your TV is not compatible with your speakers or the program you’re watching on your television. Simply adjust the settings to a suitable mode.
