Air carrier pilot reported during descent there was a spark and electrical popping sounds from panels in the flight deck accompanied by a burning electrical odor. Flight crew landed safely at destination airport where airport responders found no presence of smoke in the aircraft.

Narrative

During descent there was a spark and electrical; popping / crackling sounds from panels behind and to the right of the FO. The overhead panel back lighting also went dark. We immediately smelled a burning electrical odor. O2 masks were donned and crew communication was established. The FO continued as flying pilot. I [requested priority handling] with ZZZ Center for fumes and smoke in the cockpit and that we were proceeding direct to ZZZ; ZZZZZ intersection. The non-alert; smoke/fire/fumes [checklist] was completed to the landing section. I positioned my Emergency Vision Assurance System (EVAS) on the top of the glare shield but didnt inflate because smoke was not a visibility issue at that time. Approach briefing was completed for XXR. We elected to autoland due to wearing O2 masks. Landing was normal and vacated XXR at taxiway 1; stopping between taxiways 2 & 3 were airport CFR was standing by. Cockpit windows were opened to vent fumes. After CFR found nothing abnormal on the outside of the aircraft we taxied to the area between [taxiway] 4 and spot XX on ramp XX. I elected to shutdown the aircraft down without APU or EXT power because the original problem was electrical. We also determined that an emergency evacuation via slides was not necessary as there was no presence of smoke. Emergency slides were disarmed and the left side door was opened with the emergency pneumatic bottle. Crew stairs were brought to the aircraft. CFR entered and said their scanners were showing no smoke.
