@luismano90 horizontal lines are almost always caused by a failed driver on the LCD driver board. It is part of your panel and schematics. etc., are most often not available. We would need to see what this looks like. Post some pictures with your QUESTION. Adding images to an existing question Update (09/12/2020) This does look like a driver error on the LCD boards. For now, I would leave it alone and try to get used to this line. We’ll continue to find a schematic etc. to try and resolve this issue.
