How to service
Strategy
The television is to be serviced in the customer’s home.
The static-protective field service kit must always be used when the product is
disassembled or modules are being handled.
The repair involves replacement of the Main chassis, DVD main chassis, module(s),
fan(s) or LCD panel.
The replaced modules must be returned for repair at Bang & Olufsen, Module
Repair Department.
Fault description and error codes must be returned with the replaced parts.
Use the Module Repair form or the form in the Retail Order System, Exchange
Module.
The EEPROM 6IC6 must be transferred to the chassis in the television, hereby
maintaining the customer settings.
The ServiceTool is required in several service situations, e.g. update of SW or
changing the region setting.
Refer to the ServiceTool for full description of features and operation.
Preparations before service

Fault description and error codes must be returned with the replaced parts.

must be returned with the module(s).
