The blinking and flickering issue can be a real concern, especially when the users are trying to fix it for longer.
Going through this in-depth article will certainly help you in solving the issue.
Your LG TV can blink and flicker due to a lot of reasons. Here are some of the known causes for this issue:

If your LG TV screen is consistently flickering and blinking, then it strains your eyes, and it becomes almost unwatchable.
The LG TV blinking issue can be fixed by performing the troubleshooting steps mentioned below.
1) Check Your Connections
The cable connections can cause the LG TV to flicker. Make sure the TV is properly plugged in. If you have plugged the TV into an outlet, then plug it back into the wall and check whether it fixes the problem.
Also, in a few cases, a bad HDMI cable can cause flickering issues.
In this case, you will have to take down your mounted TV and switch out the HDMI or you need to check a new outlet.
Check the Cable Converter if the first troubleshooting method couldn’t resolve your issue.
2) Check The Cable Converter
If you are using a cable converter, then it is important to check whether it is powered correctly.
There are a few converters that come with a charging cable, while others do not need to be powered.
If the TV USB port isn’t powered or it can’t supply sufficient power then it will lead to flickering or blinking.
Therefore, it is recommended to plug your converter into a wall outlet other than plugging it into the TV USB port.
If the TV is still blinking then check the internet connection.
3) Check The Internet Connection
If your TV is connected to any device and you’re watching something on it then you need to check the internet connection first.
In this case, switching off the router and waiting for a few seconds can help in resolving this issue.
After you turn on the router reconnect it to the internet and check if the issue still persists.
Also, placing the router closer to the TV will make the signals stronger.
Go for a Soft Reset if the problem persists.
