[LG OLED TV Screen] I see vertical lines or stains on my screen

Troubleshooting

OLED TVs use display technology that emits light on its own, resulting in brighter and clearer picture quality compared to regular products.
However, this can cause heat on the screen and make images, such as the logo of a broadcast channel, remain on specific areas of the screen when displayed for a long time.
To resolve this issue, the [Pixel Refresher] function is available to use.

Do they persist even when you turn off the TV and turn it back on?
