I've a MacBook Pro A1278 that I don't use that much.
Last time I've power it on it has a strange issue with the display. It turn off after a while. And after a couple of days of usage it also start to do weird things. Like if it's distorted.
So I decide to open it and luckily I've find it just a little bit of crust on a component next the display connector.
It just takes a little bit of isopropyl alcohol and time to clean this and make this MacBook working again.
Not a big repair, but still one. So maybe if some other has this same issue, you can go and check for that component.
