## Discrepancy

WHEN ENROUTE AT CRUISE OVER THE SLC, PILOT SUDDENLY NOTED AN ELECT BURNING ODOR, & NOTICED THE ELECTRONIC HSI SCREEN DARK. THE ODOR  PERMEATED THROUGH ENTIRE CABIN, ALERTING PAX TO AN ISSUE. UNKNOWN WHETHER BURNING WIRES WERE TRANSIENT OR COULD ESCALATE, & OUT OF CAUTION, WITH INTENTION OF DEALING WITH THE ISSUE, DECLARED AN EMERGENCY & BEGAN AN EMERGENCY DESCENT, DIVERTING TO PROVO. HE RAN EMERGENCY CHKLST & ACTED ACCORDINGLY.  AFTER LANDING AT KPVU, A CAREFUL EXAMINATION OF COCKPIT & INSTRUMENTS, DETERMINED THAT NO SIGNS OF A FIRE, SMOKE, OR MELTED COMPONENTS. FIRE DEPART UTILIZED A FLIR CAMERA TO LOOK FOR UNUSUAL HOTSPOTS BEHIND THE PANEL, COULD NOT FIND ANYTHING OUT OF USUAL HEAT RANGE. CAME TO THE DETERMINATION THAT THE SINGLE SCREEN HAD SHORTED OUT.  MAINT PERFORMED & DETERMINED THE EHSI HAD SHORTED INTERNALLY.
