Hi, i've got a Late 2011 MacBook Por 15" (SN: C02GT55KDV7M) from a friend of mine and i'm trying to figure out what to do with it.

From what i know the computer was exposed to moister and the screen went dead after a while.

My friend bought a new one and just kept this one in storage.

When i got the computer it wasn't charged so i removed the bottom cover and let it trough the night on a dry place charging, i also disconnected and reconnected the display data cable.

The next day the computer was running ok and the screen was fine.

Yesterday, after almost a month of using the machine without any complains of whatsoever vertical red lines started appearing in black areas of the screen (not all blacks, but certain blacks). There was some humidity in the room but nothing out of the ordinary.

The image is ok trough an external monitor.

I opened it again and once again checked the display data cable and noticed for the first time some oxidation (green rust) on some of the connector pins. The other time i might have overlooked.

What should i do, the computer is out of warranty and a local Apple repair shop told me by phone that they normally replace the entire screen or the motherboard in this cases.

It's a shame because the computer is running great otherwise.

Thanks!

Hi Dan, thanks a lot for your input, here is a hires picture of the connector, hope it's close enough for you to take a good look at the connector.

Thank you!
