If your LG 43UR73003LA does not have a signal, there are several steps you can follow to try to solve the problem:

Check cable connections: Make sure all cables, including the antenna, coaxial cable, or any other input cable, are properly connected to both the TV and the signal source (such as a cable or satellite box).

Verify the input source: Ensure that the 43UR73003LA is set to the correct input source (HDMI, DVB-T, cable, etc.). You can switch between different sources using the remote control.

Check the antenna or cable connection: If you are using an antenna, ensure it is correctly oriented and there are no obstacles blocking the signal reception. If you have a cable service, check for any service interruptions in your area.

Rescan channels: In the settings menu of your LG 43UR73003LA, look for the option to tune or search for channels. This may be necessary if the channel setup has changed or if you have moved the antenna.

Check on another TV: If you have another TV at home, try to see if it also has signal issues. This can help you determine whether the problem is with the specific TV or the signal source in general.
