There may be an issue with the fan.

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: PPF004
  • Additional 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!

Thanks Dan!

Isn't PCH & CPU, nothing fell on the keyboard either.

Yes, I open the hardware and check if it's all fine and also I can try the TG Pro, but I don't know if I can run this soft on bootable mode.

Thanks a loot!! =)

Do you have a second Mac system you could connect yours to in Target Disk Mode. If you do you could give that a try maybe the drive is just messed up and needs to be tested using the wipe function and reformatted (if you can copy off anything important first)

For now hold off on TG Pro as that won't help if you can't run in normal mode.
