Perform a Picture Test on an LG TV
Have you tried the previous troubleshooting methods, and yet the vertical lines on your LG TV issue have not been solved? Then, simply take a picture test on your LG TV.

Reset Your LG TV
When every fix doesn’t offer a solution, you can factory reset your LG TV as a final effort. This will allow you to completely remove the data and uninstall apps on your LG TV for a new start. Thus, the possibility of the software issue that causes the LG TV display to show vertical lines will be eliminated.
As the factory reset wipes out your TV memory, we recommend you take the necessary backup from your TV.
Contact LG Customer Service
Even if the factory reset fails, it means your TV is facing an internal hardware issue. Sometimes, a loose connection inside the circuit, issues with your LG TV backlight, or damage to the TV panel can cause this issue. To fix this problem, contact LG Customer Service to solve this problem.
