The TV suddenly goes black, what is your first reaction: take a shot? Unplugging the power supply? Or reboot?
Recently, Xiaobian saw a TV video of a 10-year-old child on the Internet, which was a whole shock! Even @Communist Youth League Central Committee forwarded! More netizens contributed to the divine comment: I am in my twenties, and I can only take a shot.
From the video, you can see the operation of this child, and I have to say: connoisseur ah ~
Check the wiring, replace the accessories, and reassemble it, and the TV is successfully lit.
I have to say that this is another one: someone else's excellent child! Although every family does not necessarily have such a gifted excellent child, the TV fault "self-help" method shared by Xiaobian can help you become an "excellent child of the day after tomorrow" on simple issues!
The TV is black and has sound
Solution: Check the plug behind the TV and whether there is looseness at the socket in a specific position. If so, fix it.
If the black screen is not improved after the socket part is excluded, it is a hardware problem. At this time, don't think about "self-help", it is the best choice to contact the relevant after-sales maintenance personnel. After all, you are not sure whether you have the ability to guarantee that you can completely put it back after dismantling.
The TV suddenly goes black and won't start
Workaround: If the power LED is not lit, it means that this is a sudden power failure due to a power connection problem. At this time, you can see whether there is a power failure, whether the power plug is loose, and whether the power cord is faulty.
If the above is not the cause of the black screen, contacting the relevant after-sales maintenance personnel is the best choice.
Vertical lines
Solution: First of all, check whether there is a problem with the connection line between the TV and cable TV and the set-top box, if there is a problem, reconnect and fix it correctly; if it is a program source problem, it can generally replace other program channels to solve.
Horizontal stripes
Solution: Find the AUTO button on the monitor, manually adjust the resolution, refresh rate, if the fault has not been solved, update the graphics card driver, and then check whether the monitor and the host connection is firm, re-plug it, and try to swap the two ends.
snowflakes
Solution: You need to adjust the signal source of the TV, the SD set-top box video is switched to the AV state, and the HD/4K set-top box video is switched to the HDMI state.
voiceless
Solution: After excluding the silent state, check whether the audio signal of the set-top box is connected to the TV, that is, whether the white and red connection lines are connected to the input port of the corresponding color of the set-top box and the TV, if there is only one channel input port for the TV, just connect the left channel connection cable (white).
Xiaobian warm tips: The above methods are only for some minor failures, and the problem of TV failures may involve many aspects such as software and hardware in the system. If you can't solve the TV failure problem you are facing, Xiaobian still recommends that you do not blindly operate and deal with it, and find professional maintenance personnel for after-sales or maintenance.
