The TV can be turned on but it has a black screen. What is the reason for the black screen?
When using the TV at home, we found that the TV could be turned on normally, but a black screen would appear. How should we solve the problem when it comes to a black screen? What is the reason for this? Let’s take a look together next.
If the TV can be turned on but a black screen appears, then we need to consider whether the TV motherboard has a black screen. When the motherboard fails, it needs to be replaced. So here, we suggest that we go to a professional master to solve the problem ourselves. We don’t have to operate it ourselves. If we operate it ourselves, it may cause a certain part of the motherboard to become loose, causing other damage.
The second point is that our TV panel has failed. When the panel fails, we also need to find a master to repair it, because if we operate it ourselves, it may cause other problems.
The third point is that the power switch is damaged. When the power switch is damaged, our TV can start normally, but if we can’t use this, we need to replace the power switch. At the same time, we should also pay attention to it. It is to see if there are any other problems with our internal connection cables.
The fourth point is that the graphics card failed, which caused our TV to not function normally. At this point, we can unplug the graphics card and then reconnect it to see if our TV can operate normally. If it still doesn’t work, we need to replace it with a new graphics card.
The last point is that our cooling fan is damaged. Since we have not cleaned the dust on the surface of the TV for a long time, the dust has covered our TV. This situation will cause our cooling fan to fail. In this case, we need to replace it with a new cooling fan.
The above is a situation where our TV has a black screen. Then we can handle these situations ourselves first. Later, if we cannot solve them ourselves, we can find a professional teacher to operate and handle them.
