Hello to everyone. Finally I bought my system, including a onkyo 606 and Boston MCS100 speakers. Last weekend a saw an entire movie on BLUE RAY with no problems (PS3 to onkyo and then to TV. All HDMI). Today I tried to watch another movie and after 10 minutes the receiver turned off. Seems that is the power protection mode. I really haven´t made any changes since last weekend EXCEPT for the fact that I changed the crappy OEM cable from the speakers to a monster cable. That's it. The movie does play with the volume on 1 but not with the volume on high (about 40). I was thinking that maybe the furniture piece where I have the receiver is not ventilated enough (the back is closed, just with a hole to pass the cables). Last weekend I saw the movie just after hooking up the system and today actually was working for a while (and hot) when I started this other movie. Any ideas? I really don't want to go through the tech service.
