Aircraft
Was in the bunk; on my break. IRO called on phone and reported FAs said they smelled electrical odor vicinity of B zone galley and also a grinding/motor noise. IRO on duty investigated and then; when IRO went back in flight deck; phoned me in the bunk. I got up and investigated. There was still a very slight odor; but the grinding/motor noise was imperceptible. As I was walking around the cabin doing further investigation; all video monitors froze. I then went to the flight deck with intention of de-powering the IFES and to SATCOM Maintenance Control. Just as I entered the flight deck; a status message labeled 'IFES Cooling Fan' illuminated. Through a process of vetting the problem with Maintenance Control and working a QRH procedure; we isolated the problem to the IFES Cooling fan and de-powered the IFES [In Flight Entertainment System]. The electrical odor was completely gone and flight continued to destination without further issues.
B777 Captain is informed during his break that the flight attendants have reported an electrical smell and a grinding noise in the mid galley. During investigation the IFE System shut down. As the Captain entered the cockpit a status message; labeled IFES Cooling Fan; illuminated. The system is depowered and the flight continued to destination.
