Using the Service Center repair guide (SCRG)
The SCRG is primary dealing with fault located in the product as a stand alone
product.
Faults that occur due to setting, link failure or other faults on external connected
equipment, can not be expected to be described.
The Service Center repair guide will explain and guide you through repair of the
product.
Symbols and illustrations
A survey of symbols are available.
Symbols are used to guide in following situations:
- User action shown in an illustration
- Reference to an illustration
The symbol  is used to refer to a specic illustration.
See 2, refers to illustration 2.
Illustrations are placed in the guide so that you can read an instruction and look at
the illustrations at the same time.
Survey of symbols
Make a shortcircuit between the marked points, usually for discharging e.g. a
picture tube
Push with nger, in arrow direction
Disconnect internal plug

How to service
Strategy
The television is to be serviced in the customer’s home.
The static-protective eld 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 Plasma Display 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.
The EEPROM must be transferred to the chassis in the television, hereby
maintaining the customer settings.
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.
Plasma Display Panel pixel test
Check the PDP for burn-in and pixel error! Refer to page 1.19.
The test is used:
- before transporting BeoVision 5 – 42 or the Plasma Display Panel to a workshop.
- before and after service on the Plasma Display Panel.
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.
Recommended tools for service
Service stand (part no. 3375289).
B&O Test tape, for geometry check (part no. 6780000).
Ruler for geometry check/adjustment.
White gloves.
Micro bre cloth for cleaning (part no. 3375706).
ML-tester (part no. 8053404).
B&O programmer (ML kit must be installed) (part no. 8053368).

PIN-code setting prior to service
The user guide gives the full information concerning the function and use of the
PIN-code, such as the purpose of the PIN-code, activating the pin-code, forgotten
your PIN-code, etc.
This section gives information handling PIN-code in the service situation.
PIN-code active prior to service
If the PIN-code is not deactivated prior to service, you must use the service code to
unlock the product.
Service code.
The service code:
- Unlocks the product, but does not affect the pin-code setting
- Gives you 12 hours service time
Entering the service code.
When the product asks, for PIN-CODE press and hold l for 3 seconds.
The master code menu appears.
Enter the service code: 1 1 1 1 1.
Important notice concerning service time.
The service time is active as long as the product is connected to the mains,
including Standby.
To obtain maximum service time:
Only connect the product to the mains while you are performing actual service on
the product.
When the service time is expired, the product can only be unlocked by entering
the PIN-code or the master code.
Registration of the modules.
The modules will be registered to the product in the following situations:
- the product has been connected to the mains for more than 12 hours, including
Standby time.
- the PIN-code is activated or deactivated.
PIN-code deactivated by customer prior to service
With the PIN-code deactivated prior to service you must be aware of the modules
will be registered to the product in the following situations:
- the product has been connected to the mains for more than 12 hours, including
Standby time.
- the PIN-code is activated or deactivated.
The registration of modules in the product can only be changed at Bang &
Olufsen, Struer.

Handling and cleaning
Static electricity
Static electricity may damage the television.
Static-protective eld service kit.
A static-protective eld service kit must always be used when the product is
disassembled or modules are being handled.
Follow the instructions in the guide and use the ESD-mat for both old and new
modules.
Please note:
When mains voltage on the television is required, remove the connection between
the television and the ESD-mat.
The chassis or modules must always be connected to the static-protective eld
service kit or placed in an ESD-proof bag.
Symbol of safety components
When replacing components with this symbol, the same type has to be used, also
the same values for ohm and watt.
The new component is to be mounted in the same way as the replaced one.
Lithium battery
WARNING
Short-circuit and overcharging of some types of lithium batteries may result in a
violent explosion.
Transport and handling
The product must not be placed on the contrast screen.
It is recommended to use the product cover when transporting the television.
The product cover can be ordered, part no. 3375015.
The Plasma Display Panel must always be placed vertically to avoid damage to the
screen, such as pixel error.
Place the Plasma Display Panel in the service stand at all times.
Cleaning
Please refer to the chapter “Final check after repair” or the User’s guides.
