Question about Yamaha RX-V550 Receiver
On multiple occassions when watching a movie, the volume is turned up to hear the dialog and then if the scene quickly turns to action where a loud noise is involved such as gunfire, the receiver shuts off. When I turn it back on the display reads "check speaker wires." This is only happening if the receiver is turned up to at least -20 or so but during quiet parts of a movie, that's needed just to hear the words. I've checked the speaker wires and they all seem fine. I spent a lot of money (for me anyway) on this system including Paradigm surround speakers and it seems like I should be able to watch a movie at these levels without the receiver shutting off. It seems to be doing this to protect the speakers?? Any way to increase the level that causes this to trip? Any suggestions? Thanks!
Its eather a defect with the reciver top end shut down /over bias system , Or the speakers could be partially shorted, such as instead of being 8 ohms, the speakers could have a few shorted windings from a loud music event?? I would take the speakers in to be checked under load. NOT just checked for resistance.. A regular shop may not know how to do this BUT tell them you need to put the speakers under a load and then measure the resistance . GOOD LUCK
