[LG TV] Lines, Spots, Dots on screen

Troubleshooting

If abnormal lines, dots, and spots disappear when you change the screen content, the issue may be related to the TV input signal or display aspect ratio.
To troubleshoot, check the TV aspect ratio settings, verify the antenna cable connection and signal input settings, replace the HDMI cable, and change the input signal to a different device.
Additionally, perform a Picture Test.
If problems persist even after a Picture Test, please contact LG Support for further assistance.
