Hello everyone[br]
[br]
I have an mac pro late 2013 which i bought it from someone as defective.[br]
He sad one morning it stop working and Apple could not find the issue.[br]
[br]
I have started troubleshooting and came across to this point where GFXB Check lights on on the bottom logic-board. When i read the Manuel it says that, :[br]
”***GFXB Check:*** This indicates that there is a connection issue between the logic board and Graphics Board B. Check the mezzanine connectors on both the logic board and graphics board to be sure the connections are fully seated.”[br]
[br]
I already checked the connections where two pins were bent (I think this guy has tried to fix him self and bent it while assembling back)I swap the cable from Board B to Board A but it still on, that means its maybe not the cable.[br]
[br]
My question is, can it be something else if yes what should i go after.[br]
I have the lights on except the power button light is off.[br]
[br]
I have 5 Diagnostic LEDs on io/board[br]
Thank you.[br]
