sub woofer/amp

[Bravia55HX]

Hi Guys,

i'm in a bit of a dither, its taken me almost a year to set this up again and i cannot seem to get the sub to work (M70AS) everything is connected but the Amp (STR-DB830) is saying "not in use" when i press sub button 😕 even running the THX optimiser disc in sound test there's nothing from the sub and its done my head in now, any idea's i should add that the LFE graph on the amp shows its out putting but there's just no sound.

oh, that dreaded crease!, swapped the 923 out twice before i was happy then along came the pixel problem but because i was told swapping the panel for another of the same it may not solve it, that was a funny year for panel problems wasn't it.

seems we gone off topic but never mind!
