What was found
DURING INSPECTION, THE CABIN LOUDSPEAKER RESISTOR R0223, ON THE LT SIDE WAS FOUND BURNED OUT AND THE ADJACENT WIRING THAT HAD BEEN SECURED TO THE RESISTOR HAD OBVIOUS HEAT DAMAGE TO THE INSULATION RESULTING A BLACKENED MELTED CONDITION, NO BARE WIRES WERE YET EXPOSED. A CHECK OF THE IPC AND WM FOUND THE WRONG PN RESISTOR WAS INSTALLED, MOST LIKELY AT THE FACTORY. FURTHER INSPECTION REVEALED RESISTORS R0224 ALSO ON THE LT SIDE, AND R0222 ON THE RT SIDE WERE THE WRONG P/N, BUT NO INSULATION DAMAGE WAS NOTED.
