Thin Black horizon lines on top to bottom of screen

Hello,

I have a Samsung QN75Q7FAMFXZA QLED TV. There are thin black horizonal lines on top to bottom of screen. When sitting far away, lines are less noticeable than in front of it. Is the issue with screen or one of the boards? Thanks

@tnyn horizontal lines are caused by the panel, not the boards that are replaceable. These can originate on the LCD drivers (scaler boards), failed source driver or LCD damage. We would need to see more to try to get more specific
