So I bought a refurbed unit from HK via ebay and I'm starting to regret it. When I'm watching a movie the receiver will just turn itself off. It could be a very quiet scene, or it could be an action packed scene, there doesn't seem to be any rhyme or reason to it. My system consists of a HK Signature 5 channel power amp which is powering the speakers, Denon DVD player, and JBL Studio series speakers all around (4 S38ii's and S-center). I've tried moving it to different outlets, but since my power amp is powering the speakers it shouldn't be drawing that much power. I'm just wondering if there is anything I could try before I box it up ship it out and look for a replacement.
