As soon as the program is broadcast on the TV, there is a black screen and a sound. What is this? Why is this?
In the process of using the TV, we will find a situation, that is, after the TV broadcasts the program, there is a phenomenon of black screen, but there is a sound. How should we solve and deal with this situation? What is the reason? Let’s take a look at why this situation occurs.
First of all, there is a problem with the TV signal source. When the TV signal source fails, it will cause sound on our TV, but a black screen. In this case, we need to refer to the local weather conditions to see if the local weather conditions are normal. If that day was a heavy rain, the signal reception at our home was not particularly good at this time. In fact, we also need to pay attention to our signal source. It may be damaged and cannot be used normally. We need to pay attention to this.
The second point is that the TV settings in our home are faulty, which prevents the TV from being connected and used normally. In this case, we need to check whether we have made any mistakes in the settings or made them into another signal source.
The third point is that our TV hardware has failed, which has caused this problem in the TV. When the backlight board of our TV fails, our TV cannot see any images. In this case, we can only find a professional master to carry out repairs. We cannot handle it ourselves. In fact, there is another point that there is a problem with our motherboard. When there is a problem with the motherboard, it will also cause our TV to not be used normally. Well, here, it is also recommended to find a professional master to carry out repairs. If we operate it ourselves, some parts may fall off during the operation, resulting in our TV not being repaired.
The above is one reason why there is a black screen when our TV shows a sound. When encountering these situations, we don’t need to worry too much. We can find a professional master to carry out testing and maintenance before using it later.
