The TV cannot be turned on. What should I do if a black screen cannot be turned on?
In the process of using the TV, have we ever encountered the problem that the TV cannot be turned on and has a black screen? So if we encounter this situation, how should we solve it? What caused this? Where did the TV fail? Let’s take a look together next.
The first problem is that our TV cannot be used normally due to a failure in our power supply. Generally, when our TV has a black screen and cannot be turned on, it means that there may be a problem with our power supply. We can check whether our TV plugs, sockets and boards are normal. If all three things are normal, it means that there is a problem with our internal wiring. We can use a test pen to test our plug and socket boards to see if the end of our test pen lights up. If the end lights up, it means that all three of our things are normal. That means that there is a problem with the internal wiring of our TV. In this case, we need to find professional personnel to repair our TV.
The second point is that our TV signal interface has failed, which has caused our TV to have a black screen. In this case, we need to restart the phone and turn it off to see if our TV can return to normal.
The third point is that there is a problem with the backlight of our TV, which causes our TV to have black screens, black screens, and white screens. In this case, we need to find professional personnel to inspect our TV backlight. After checking it, we will replace it to prevent future battery problems.
The last situation is that our driving backlight board circuit has also failed, which causes the TV to not be used normally. In this case, we need to inspect our driving backlight board before using it.
Then, when our TV at home has a black screen, we can consider these problems and use these problems to solve some situations where our TV cannot be used normally. If we cannot solve it ourselves, we must find a professional master to handle it.
