#2 Repair of BeoVision 1
Before troubleshooting is initiated, let the customer explain and demonstrate the
fault, if possible.
Afterwards, check:
- that all cables are plugged in correctly
- that the mains voltage is connected, and switched on
- that an aerial signal is connected
- that all external sources such as VTR, DVD etc. are connected correctly and
switched on. Use the enclosed IR-blaster if necessary in order to check IR-signals to
the external sources.
When troubleshooting is initiated, please refer to #3 Fault flow chart. The fault
should fit into one of the 5 main groups.
- System functionality
- DVD/CD (BC1) / Camcorder
- Picture
- Sound
- Satellite (only if a satellite module is mounted)

Introduction, English
Follow the arrows from each box, answering YES or NO, to locate the fault. The
back cover may have to be removed and the main chassis placed in service position.
See 10.1 Disassembly of BeoVision 1 and 11.1 Main chassis in service position for
further information.
If measurements are needed, please refer to the chapter measurements, placed
behind #3 Fault flow chart.
When a voltage specification is given in the fault flow chart, a value within ±10-20%
of this is OK.
If nothing else is mentioned, the fault flow chart applies for both BeoVision 1 (BV1)
and BeoCenter 1 (BC1).
When replacing a module, remember to disconnect the mains voltage. Carry out
the replacement, and reconnect the mains voltage. Then check if the fault is
rectified.
If replacing the main chassis remember to transfer optional modules, such as
Satellite, STB-Controller etc. to the new main chassis.
For information regarding operation of BeoVision 1, see Brief operation guide.
After repair of BeoVision 1, always remember to follow #6 Adjustments after
replacement of main chassis and/or #7 Check after replacement of main chassis or
modules.
Important note concerning theft protection, if activated:
Before servicing the product, please ask the customer to deactivate the theft
protection, if possible.
- If the theft protection is active during service, please note that exchanged modules
must always be returned to Bang & Olufsen for service. The exchanged modules
will immediately, after mains on, be registred to this product and this registration
can only be changed at Bang & Olufsen, Struer DK.
- If the back-up suitcase is not being returned to Bang & Olufsen after use, but
refilled by e.g. the dealer or workshop with new modules, please read the following
instruction.
When exchanging modules to see whether they are defective or not, it is important
to use the Service code, to avoid registration of the modules for this specific product.
...When the TV is turned on, use Service code, pressing lfor 3 seconds.
A Mastercode menu appears, and the Service code, which is 11111, must be
entered.
It is then possible to exchange modules to see whether they are defective or not.
If not, the registration of the module will not take place until for 12 hours, time
enough to replace with the old module again.
