Boston Acoustics soundware XS subwoofer

[orcadian]

Hi,

I am a new member and I have a dead subwoofer.

Has anyone repaired a dead amplifier on a Boston Acoustics soundware XS 5.1 subwoofer - I believe it is a common problem?

There is no output from the main power supply board but there is an input of 35V ac from the smaller relay power supply board, which does not seem right.

There are no obvious failed components on either board.

Any help, ideas or a circuit diagram would be most welcome

My XS subwoofer is dead too but I've narrowed it down to the amp board. I see that it's burned out. I contacted BA and there aren't any replacement parts through them. Does anyone have any suggestions as to where I can get a replacement?

Any help is greatly appreciated.
