In this section, we will mention some of the key reasons for this problem. The problems are gathered after gaining practical experience.

1. Certain changes In Temperature

When you are hearing a popping and cracking noise, then you have to understand it is because of the sudden temperature felt by your device. When the Tv is turned off, the temperature remains lower. 

The temperature rises sharply when it is turned off. As television consists of many metals and plastics that’s why it is affected by sudden warmth. That is the reason you are hearing popping noise.

Usually, the pitch of this sound is very high. The sound does not last for more than ten to fifteen minutes. If all the symptoms match then you can be assured, the sound is initiated due to a sudden temperature change.

2. Electrical Feedback Is The Main Culprit

Now in such cases, you won’t hear any popping noise or clicking noise. If you are hearing a buzzing or humming noise, then the main reason behind this is the faulty signal provided by the electricity system.

For some reason, the electric system can be faulty. For example, when the extra current is not passing through the ground then it enters into the electric system of your device.

Samsung tv provides a resistor that does not allow extra electricity. But it makes a high-pitched noise when the amount of current is much higher. Due to this reason, you will hear a humming or buzzing noise.

The pitch of this sound is very high, the sound suddenly goes off after the television finds itself in a stable situation. So, you have to check all the attributes mentioned above. If all things match then you have to check the electricity system.

3. Problem With The Power Transformer And Adapter

A chirping noise is usually heard when there is something wrong with the power transformer and the adaptor on your device. Samsung television is widely popular for its performance.

Sometimes, fewer devices might have a power transformer that can not convert the direct current and alternating current. Due to this incompatibility, you will hear a chirping noise.

Another issue can be that there is some problem with the adapter of the device. When the adapter is not working properly then your tv will not cope with the extra current. Then you will hear a chirping noise. 

The longevity of this sound is more than the previously mentioned sounds. The pitch is usually very high. So, you also have to look at those attributes to match whether you have an issue with the transformer or with the adapter.

4. Problems With The Sound System Of The TV

This is a minor problem, usually, a sound is created while turning on the television. When the sound system of your device is not properly working then you need this small amount of sound to be amplified a lot.

As a result, you will hear a high-pitched noise. The longevity of this sound is lower than other sounds. The pitch is relatively lower than the previously mentioned sounds. You can even hear this sound for only a few seconds.
