MacBook Pro 15" Retina (Late 2013 Mid 2014) Black screen but I can see my cursor. After a few test, like reinstall Sierra OS, I run an Apple Diagnostics (“D” at boot up) with this result: There may be an issue with the fan. Reference Code: PPF004Additional reference code: PPF003 Which fan matches with the code PPF004, right or left? Or I need the both? Thanks =)
I’m a bit confused here. A Black screen with a moving curser would imply you have PCH or CPU level problem. Then you talk about getting PPF003 & PPF004 errors which are the fan’s. But, if you can get into diagnostics then the PCH & CPU are working here! So lets back up here a bit… Did you spill something into the the keyboard and/or trackpad and/or sit the system down on a wet surface? I’m suspecting you have liquid damage here (It could have happened a while ago). If you didn’t get the system wet did you have your system served at some point? I think you’ll need to open the system up so check the connectors and inspect for dust buildup on the fan’s and fins. Using a soft paint brush carefully scrub the logic board, fan and the heat sink fins then use some can’ed air to blow the junk away. You may want to get a more informative tool here: TG Pro. It will give you a better idea on whats happening for less than $20 its well worth it!
