I have used this model number BCM94360CS which can be bought cheaply Ebay and works great. I have perfect AC connectivity.
You really need that tape, If still no sound after placing the tape in place, then you might have damaged the flex cable. Worthy to mention, that some replacement screens come without the ambient light filter (white film seem on the screen) and without the plastic brackets for the camera and proximity sensor, which in those cases, you would have to transfer those parts to the new screen. Also in some screens, the holes for the proximity sensor are not properly done and you might end up with a non-working proximity sensor. In those cases, just remove the pain with the spugger where the proximity sensor locates (removes the black paint) and then add some black permanent marker over it to make it black. That way, it will look pristine form the outside but just thin enough for the proximity sensor to work.
For anyone performing hardware exchanges, there is a free app on Apple store called Dr. Phone that can be used to test the several hardware components… Nice to do before closing it up..
