1.2 How to service
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 chassis, module(s) or LCD panel, which are
supplied in the back-up suitcase.
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.
Service Tool
ServiceTool is required in several service situations, e.g. update of software.
When it is necessary to replace module 999 main chassis, use ServiceTool to read
out settings in the microprocessor. These must be transferred to the new
microprocessor to maintain customer settings, production settings and pin code
data.
In cases where it is not possible to read out the info in the microprocessor, a new
pre-programmed microprocessor can be ordered in Bang & Olufsen Retail system.
Refer to ServiceTool for full description of features and operation.
Please note:
When the main chassis is replaced, check software versions and update if
necessarry, by means of ServiceTool.
Preparations before service
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.
Fault explanation and demonstration
Before troubleshooting is initiated, let the customer demonstrate the fault, if
possible.
Error code
The error code contains data that may be used for repairing the module(s) and
must be returned with the module(s).
Handling the error code.
1. Take a note of the error code, for example on the Module repair form.
2. Use the error code when trouble shooting.
3. Return the error code, either on the Module Repair form or in the Retail system.
4. Before returning the television to the customer, clear the error code.
