Why the TV screen turns black when it lights up:
1The wiring was not connected properly
You know, if the wiring of our TV at home is not properly connected, our TV will not be able to use normally. Here, we first check whether the wiring of the TV itself is properly connected. If the audio and video cable is not properly connected, it will cause our TV to turn black when it lights up. Then here we need to unplug this cable and reconnect it. If there is a problem with our switch, it will also cause our TV to not be able to use normally. Here, we need to unplug all the socket switches for testing and then install it to see if our TV can work normally.
2There is a problem with the motherboard
It is inevitable that some problems will occur when TVs have been used for a long time. If the motherboard of our TV will become damp and cannot be used normally when the home is very humid, then we need to find a professional master to repair our TV at this time. If it is a problem with the motherboard, it is not recommended for us to repair it ourselves, because repairing it yourself may damage other wiring. Secondly, we exclude the fact that the motherboard is damp and it may be that a certain part of our motherboard is loose. As a result, our TV cannot be used normally.
3The TV connector is loose
If the interface is loose, our TV will not be connected normally. At this time, we need to adjust the interface. Otherwise, this problem will often occur. In this case, it is recommended to find a professional master to repair it.
The above is the reason why our TV will turn black when it lights up. If we encounter it in daily life, we can compare and analyze it. If we encounter problems that cannot be solved, we must find professionals.
