One single purple line on the screen and battery ko
I try to write in English: a friend of mine gave me its macbook pro A1502 because he has some strange problems with it. A vertical purple line appeared after the "complete" format of the system to restore the latest version of OSX compatible with this laptop (Catalina) and, in the meantime, the battery appears to be completely death (if I detach the magsafe charger, the computer stops immediately to run). Using Ubuntu, before the format of the system, the purple line seemed not to appear (I remember this particular): I opened the macbook and it doesn't appear water damaged, both for screen and for battery plug. I tried to re-install Ubuntu (22) and the line remains on its place...any idea? Is there any test that I can do? Can I try to change the display cable?
Waiting for your answers, thanks in advance.
This is what I can see on the screen: it seems that the purple line "changes" its colour near other pixels which should be, for example, white or light blue. Any idea?
I tried all the tricks and no one worked unfortunately...I am looking to the line and it seems that it changes a little bit colour, according to the background image; exactly, in the first hours I saw it, it appeared to be purple, but now it has a colour mix similar to the background image I had on linux ubuntu distro.
Here the report proposed by coconut battery:
Is this a good question?
@ilgaglioffo sounds like a display instead of an OS issue. Post some pictures of what your screen shows you, with your QUESTION. Adding images to an existing question
@oldturkey03 - Andrea has two issues: battery/charger & the display.
To work the 1st we need macOS so we can use CoconutBattery to get the batteries status and the batteries charging.
@oldturkey03 Thanks, I added a photo; I am re-installing OSX in the meantime.

@ilgaglioffo a new battery and a new display is all you need to be back in business with your MBP. Best of luck!
