Hi So I've bought this one of ebay recently. Previous owner claims, it was in full working order. On that day when it has arrived, I've hooked it up to my router and updated firmware via internet.It was late, so I didn't connect my speakers at that point.On the next day, to my surprise, I couldn't get any sound out of it. Tried hdmi, bluetooth, analog,airplay, home network..nothing (although speakers relays where on) Turns out, you can reset this Sony receiver to three different modes: Shipment mode, All Clear Mode and User Mode. I've done all these and voila! Sound was back on Now, here comes the "weird part": -sound goes off when music optimizer is set to Low or Normal - comes back when set to OFF -I get sound while playing FLAC files but not with MP3's ( ) - works fine with A.F.D/2ch, multi-stereo and few other modes but not with HD-D.C.S sound field. I believe, this is a firmware issue rather then hardware, but I'm not 100% sure. Does anybody know, how to force update via usb or perhaps have any ideas? Thanks.

I've managed to fix it I believe the problem was caused by poor communication between DSP and SD-RAM IC.I've re-soldered couple of sd-ram's pins and two smd resistors.

That's good. Hopefully it was just a cracked solder joint.
