Aircraft
Took static discharge while flying through a moderate non-CB rain shower (tops 10;000 ft) on the departure from ZZZZ. Discharge knocked out both Captain forward displays and First Officer outboard display. Captain's forward window heat went inop. Flight deck door power went inop. Status message also showed 'ELEC P300 DISTR CHANNEL'. Autopilot continued to work. Initially monitored autopilot using ISFD with existing map displayed on inboard First Officer Display unit. Reconfigured displays to put reduced PFD and EICAS on First Officer's inboard display and alternated lower display unit halves between CDU / Checklists / Synoptics / Map. Ran all appropriate checklists; unable to restore displays. Pinned cockpit door. Fully engaged both IROs in VVM; communications; and problem solving. [Briefed the] flight attendants; made customer announcements; requested fuel dump area and were provided vector racetrack pattern for fuel dump. Requested vectors to final; uneventful normal ILS and landing. HUDS were operative. Aircraft status can best be summarized by saying that it was a completely normal airplane (except window heat and flight deck door power) behind three dead displays. All other systems functions normal. Multiple logbook discrepancies entered. No overweight landing. No altitude deviations; no deviations from clearance. Fuel dump info transmitted to [ATC] via SATCOM.  [The Check Airman] (Captain) was flying from right seat with IOE Captain in left seat on a pilot monitoring leg. Fuel dump specifics: Dumped approx 50;000 lbs at 9000 feet.
[Report narrative contained no additional information.]
An airliner suffered the loss of three of four forward displays following a static discharge as it climbed through 10;000 feet after takeoff.  Crew dumped fuel to max landing weight; and returned to their departure airport.
