A system for using a troubleshooting engine to assemble an interactive multimedia repair guide for assisting a service technician in the repair of a defective product, and a mehof of using the same. The system includes a dynamic knowledge database for storing product history records relating to defects reported concerning the product. The database also contains design information related to the product for correlation with the defect reports and use in analyzing future reported defects. A product performance counter (PPC) analysis module receives PPC data from an individual product, generates a PPC profile based on the received data, and compares the profile to stored design and historical PPC profiles to produce a weighted prediction report of likely defects. This report is transmitted to the troubleshooting engine, which directs a multimedia application to transmit diagnosis and repair instructions to a service center technician. The database is formed of separate portions, embodied at separate geographical locations and storing records in different languages.
