My 347s subwoofer output seems to have died - I think am experiencing the same issue as this thread -

I ensured that my cable and subwoofer are okay by connecting the subwoofer to the audio out section of my oppo blu ray player. There the sub worked perfectly.

I have tried the test tone generator and there seems to be no sound generated for the sub.

Any ideas on whether this might be something that can be repaired ? Or some other OSD setting that might be missing ?

Here is my setup ->

Source - Oppo BDP 83
Receiver - Harman Kardon 347
Front Speakers - Paradigm Studio 100's
Surround speakers - None and set to None in the OSD
Subwoofer - JBL HTPS-400 powered sub.
