How to fix black screen?
I'm buying a 2011 13" MBP
Seller said they were watching a movie and left the room and came back and the mac was off. They said they turned it on and it boots and has black screen and unlit keyboard. Also mentioned they brought it to get looked at and they said it had water damage but seller says that water wash;t spilled on it. So the question is what could cause this and would a PRAM reset work for this and what other steps might I take to get it up and running?
High moisture can trip liquid detection sensors. . . using any computer in a high humidity environment can cause corrosion problems.
Connect to an external monitor. If that works your problem is the internal display chain, cable, controller, LCD... if it doesn't you have video chip/logic board damage - an advanced DIY repair .
