REPAIR TIPS
Service position
Disassemble the BeoLab 2 see section 6.

Back-up suitcase.
The BeoLab 2 cannot switch to ON mode without a signal transmitted from source
through the Power Link.
Dismantle the NTC-PCB from the bass unit and connect it to the chassis.

It is possible to switch the BeoLab 2 to ON mode without connecting the bass unit.
It is now possible to measure at the test points, see page 5.9.
What to exchange
If all voltages are 0V and the fuses have not blown, there may be an interruption
of the power supply in the mains trafo.
If it is possible to switch the BeoLab 2 to ON mode, but the sound is distorted/
missing exchange the bass unit.
If the mains supply is present but it is still not possible to switch the BeoLab 2 to
ON mode exchange the electrical-chassis.
If the fuses are blown, exchange of the electrical-chassis is necessary because the
failure may be intermittent.

second to reset the BeoLab 2.
