At FL350 approximately 50 minutes from ZZZ; cabin crew said we had fumes smell in row 12. Deadheading crew in the back confirmed a burning smell with no smoke. Thought it was coming from the entertainment system. Captain asked the Flight Attendant to turn off the entertainment system and see if it went away. Waited a few minutes and said the fumes still [were] there. At this time a passenger moved because she said she felt ill. Diverted to ZZZ1; Captain gave control to me; while he ran [the] checklist. I flew aircraft into terminal area. Once all checklists where complete and the Captain and I formulated complete game plan; the Captain took back control and flew an uneventful visual straight-in to XXR. Taxied clear; looked over by [emergency crew]; taxied to gate.
