  • The LG TV must be facing some temporary glitch that is causing the screen to turn black.

Disconnect and reconnect the power buttons for the TV

Sometimes, a remote malfunctioning leading to non-working TV. Therefore, you must check this by opening the TV from the power button present on the TV’s sides. The controls are located on the side of the screen or below the screen.

Open the LG TV from the button on the TV

Please do not use a remote as it is faulty too. If this works for you, open the menu option from the button present on the TV and see if there is any issue there.

You would need to repair the TV if you see a message regarding the issues faced by the TV on the screen. Usually,

Look for any problem with the power cables 

Sometimes, power cables are connected loosely or are a bit into by a rodent-like a rat. When this happens, the TV does not receive power constantly, which result in a black screen. 

Therefore, check all connections of power cords with the TV and other external outputs as well, such as a cable box, Amazon fire stick, etc.

Remember to check the power outlet as well that is sourcing the TV. An inadequate supply of power is the reason the TV does not work since it does not receive adequate power.

Sometimes, one could mistake connecting an HDMI connection at a wrong labeled port. Turn off the power before rectifying any links of the TV.

HDMI connections are a very important part of the TV as they are considered the main connections. Therefore, use good quality cables and ensure that they are connected properly to the right ports.

Look for any change in connections or connection settings

Now, look for any changes in the peripheral connections, such as the set-top box, cable box, etc. Check if they are inserted in the right port or not. Several times the main output cables of the TV, such as red, blue, and green, won’t inserted in the right port.

In addition, restart the TV to set any changes you have made in the connection settings after waiting for 30 seconds.
