Is there a way to diagnose if the on and off bluetooth on my MacBook Pro Mid 2012 is related to a frayed Bluetooth cable vs a broken Bluetooth board?

I also have the same MacBook Pro. I just swapped the board and it didn’t fix my Bluetooth issue. It’s probably the cable.

I’d call this an easy replacement to be honest. Pulling the tape back is the hardest part. I didn’t disconnect the battery for mine (as some reviews said that could cause shorts as much as not disconnecting it), and things went just fine. All together, replacement took me less than 10 minutes from start to end, and things work great now!
