Are you an LG TV user who has been using the TV for a long time? You will face various display issues now and then. You may see a vertical line or a black screen on your LG TV all of a sudden. To help you identify these types of problems on your LG TV, you should choose self-diagnosis.
This is a feature that you or your TV technicians can use to diagnose any problems with your TV display and what’s causing them. If you have basic TV knowledge and are facing any display issues, the Self-diagnosis option will give you a head start on how to fix the problem on your own.
If you find this intriguing and wonder how to use it, then refer to the following guide.
