must correct some things, cb's for ATC and TCAS are on the P11 overhead panels. acces by cocpit crew. the P110 and P210 have airground relays.. fire to the P panels or melt down, have been in both these panels. in ELMS block 2 planes. mostly current mode couplers and 1 incident the APU feeder cable was burned away. this without warnings during flight. ifo based on 15yr avionics experience and findings with B777.

bad design of the door upper plastic seal causes the loud noise. there is already a service bulletin out to get more stiffer banana leave cover plate. strangely the cockpit tried to solve it by going down and depress the cabin. its not caused by pressure just passing winds lift it up from the door. most likely this was the cause. its all just speculation and the real answer will take a while to come out.
