I bought a defective DALI SWA 15 subwoofer and the builtin Class D amplifier is not amplifying (can hear very low signal), i had contact with hifiklubben (the reseller in Sweden) so they could contact dali but they dont give out the servicemanuals to endcustomers.
Is there anyone here that can manage to get a hold of one or mabye point in a possible direction that what could be wrong ?
The fuses was blown (all 3) so the mosfets and 2 controller ic's is now replaced by a very experienced repairman.
But now he has come out of ideas. Apparently the transformer has a big load and he cant get it to be normal.
