There is no response on the black screen on the TV. What is going on? How should we solve this?
When we are using the TV, I will find that the TV has a black screen and there is no response no matter how hard I press it. What is the reason for this situation? Why did this happen? Is there a problem with our TV as a whole, or is there a problem in some places? Today, let’s take a look at a situation where the TV is powered on but has a black screen.
The first one is that our driving backlight circuit board has failed, which causes our TV to not be used normally. During our use, we can approach the TV screen and observe it to see if there are any very shallow images on our TV screen. If there are these very shallow images, it means that there is something wrong with our driving backlight circuit board. What about this situation? We can only find a professional master to repair and handle our TVs. If we handle them ourselves, other problems may arise.
The second problem is that because of our TVCPUThe cooling fan was damaged, which caused the TV to be unable to clean up the dust inside us normally. If we haven’t cleaned or repaired our TV for a long time, then our TV will be covered with some dust. At this time, our TV will not be able to dissipate heat normally, and then the screen will not be able to light up normally.
The third problem is that there is a problem with the TV panel. When the TV panel fails, our TV cannot be used normally. In this case, we cannot carry out repairs ourselves. When encountering this, we can only find a professional master to carry out repairs and maintenance. After repair and maintenance, we will see if our TV can return to normal.
Finally, our internal power supply fails, and this situation also requires maintenance. If we ignore it for a long time, it may cause damage to our internal power supply and cause other problems.
The above are a few reasons why our TV has a black screen. When encountering these situations, we can check them. If we can’t check them, we can find professional personnel to handle them.
