Behind the black screen of the TV
In our daily lives, television has become an indispensable part of the family. Imagine the frustration of being in the middle of a movie or watching an important game, only to find that your TV screen is completely black. However, in my work as a professional plumber maintenance worker, I have experienced many cases of TV black screens, where the stories are colorful, challenging and fun.
Case 1: Two TVs need to replace the light bar
One day, a housewife called and said that her two TVs had suddenly gone black, and she was very anxious. I immediately went to her home and upon closer inspection, I found that the backlights of both TVs were damaged. The backlight is a very critical component of the TV, it is responsible for providing the brightness and color of the screen, and once damaged, the entire TV screen will completely lose its display.
Replacing the backlight is not a simple task, it requires the disassembly of the TV and the delicate operation. On these two TVs, due to the special brand and model of the backlight, special customization is required, and the price is relatively high. Therefore, I suggested to the housewife to replace the light bar, which can ensure the normal use of the TV and prolong the life of the TV. Although there is a certain cost to replace the backlight, it is also a guarantee for the family, considering the importance of the TV.
Case 2: A TV can be repaired for a small fee
Another time, I received an urgent repair request about a black screen on my TV. This time it was an old-fashioned TV that suddenly wouldn't turn on, the screen was completely black, and there was no sound. The initial judgment was that it might be a problem with the power supply, so I quickly went to the site to check.
After careful observation and measurement, I found that the power cord of the TV was loose and had poor contact. I reconnected the power cord and cleaned up the nearby dust, then restarted the TV, the problem was resolved, and the TV turned on without any problems. The repair cost very little, but the fault of the TV was repaired, and the customer was very satisfied with it.
Interpretation of professional knowledge
Through the above two cases, we can see that the reasons for the black screen of the TV are different and need to be repaired according to the specific situation. In the first case, the black screen was caused by a damaged backlight, while in the second case, it was a problem with the power supply. This illustrates that the cause of a TV failure can be multi-faceted and requires a lot of expertise and experience from maintenance workers.
The backlight is an important part of the TV, and once it is damaged, it needs to be replaced in time. Power supply issues can cause your TV to not turn on properly, which is usually one of some common faults. Therefore, maintenance workers need to be familiar with the function and working principle of each part of the TV in order to be able to accurately and quickly locate the problem and fix it.
In addition, maintenance workers also need to have certain communication skills and problem-solving skills. When communicating with customers, it is necessary to listen patiently to the customer's description and judge the possible cause of the failure based on the information provided by the customer. When solving problems, it is necessary to use your professional knowledge and skills to find the most suitable solution, and to ensure the quality of maintenance and customer satisfaction.

Although the black screen of TV is a common fault, there may be a variety of different reasons behind it, which requires our maintenance workers to have rich professional knowledge and experience.
