Black lines on macbook pro screen

[Kelly Greer]

Sigh. Do you have any experience with thing black lines appearing on the screen? Then if I move a finder folder or switch apps, the photos leave remains. I followed most of the instructions I found on Google, other than updating to the newest OS. I'm assuming I've got a connection issue? 

MacBook Pro, 15 inche 2019 (old, I know) and I attached the rest of the "about this mac section." I'll get on my phone and try to attach a picture of my screen.

Oh, and if I close the laptop, the lines go away until I move something on the screen.

Well, this isn't good. The things that cause this issue are usually 1 out of 3, or even a combination of them: 

1. Loose / Faulty Display Cable between the Motherboard and Display
2. Display Panel itself. 
3. Graphics Card issue, but since it's built onto the main board, it's a Motherboard Replacement, which isn't cheap. 

If you don't want to take it to Apple, and pay out the nose for the repair, I'd recommend Rossmann Repair Group. Louis and his Team moved to Austin, TX from NYC. They do these types of repairs all day long and will go as far as component level repairs, rather than just replacing the board. I'd contact them for a quote. If you head to Apple, automatic $1000 at the very least for this type of repair, between parts & labor.

That's what I figured. I'll look into them, thank you. At 6 years old, probably better to save my money for a new computer than fix at Apple.
