EON10-G2 Troubleshooting Guide
The purpose of this troubleshooting guide is to enable the experienced service
technician to quickly become familiar with the operating characteristics of the unit and to
accurately diagnose the associated symptoms of malfunctioning circuitry to their root
causes. In addition, this guide will facilitate the timely repair of the malfunctioning
equipment so that it can be returned to a satisfied owner. Since the total ‘repair time’ equals
the sum of the ‘diagnoses’ time plus the ‘circuitry repair’ time, and the ‘circuitry repair’
time is standard, the only other factor that can impact this total ‘repair time’ is the diagnoses
time. Therefore, the successful technician, must be time efficient with respect to diagnosing
and repairing malfunctioning equipment.
Isolation of the defective circuitry can be accomplished by utilizing this guide and the
circuit descriptions found on the previous pages. Generalized faults of current, voltage and
signal irregularities will constitute the bulk of the repairs necessary to the EON 10-G2.
• Visually inspect product. Many times a customer's problem with a unit can be located
just by visually inspecting the product for gross faults. This visual inspection can also
determine if the internal damage is related to equipment abuse.
• Verify the fault that the customer is experiencing. If unable to reproduce the customer's
complaint, notify the customer of your findings and obtain more information about the
complaint.
• It is suggested to always use the original JBL replacement components that are listed in
the master parts list to insure the maximum performance of JBL equipment. More
