TX-SR875 Output only on Front L and Front R

Hi All

I have some serious problem. My amp is out of warranty and got some serious problem: i have only sound on Front L and Front R. On other outputs is silence.
Amp detectin Digital Input signal without problems (coax and optical).
I checked out with TEST NOISE but i hear noise only in Front Speakers. Tried to reset my , unpowered it for 24 hours, checked all options in menu but still nothing.
When I turn On from Standby Mode i hear: 1 click , after 1 s another click and after another 5s one more click. And thats all.
I am out of ideas what it could be. PLEASE, Help me guys. :-(

P.S. I am from Poland. And my HDMI doesnt work too but i dont need hdmi , only sound.
