Bluetooth unavailable + Screen flicker on MBP mid 2012

文本:

Eek! A few weeks ago (right after I discovered the data-& energy-saving “tether via bluetooth” function on android, sigh..) I found that my MBP showed me the “bluetooth unavailable” symbol in the icon bar: A greyed out icon with a sawtooth wave on front of it. I could not connect to any device, no submenu is shown.

But: this does occur randomly! So I guess this is some hardware defect?

Additionaly, recently when I opened the MBP, the screen would flicker initially (not the green-stripe flicker, but some flashing, then grey/white noise, then the standard screen, with the “BT not available” symbol.

Is the BT antenna somewhat connected to the screen cable? Is there something I can do to fix the BT issue and to prevent things getting worse?
