Reinhard,
I check it. I connect only right worked channel from 9240. Of course disconnected old, and connected the same cable colours.
After that, I can hear any sounds in both channels. I come back with connections, and 9240 worked right (uffff ), but 9141 right channel working like before (with discharged sound), but left channel not working.
I must check it in headphones, bu I'm affraid, left channel is broken.
Volume is only max 3 leds level tested, not more, and some 30 seconds time.
