I just bought a Yamaha HTR-5790 through Best Buy's online site and have spent 3 days trying unsuccessfully to get it to turn on. The symptoms: I press the Standby/On button. I hear the amp click and the display briefly turns on then goes blank and the receiver won't respond to anything I do. I keep hearing that it's unlikely that the receiver has an internal problem and that I'm doing something wrong. So I'm hoping this forum is the right place to get a solution. I have the receiver plugged into a Monster Cable power strip. For now, I'm only using 2-channel 8-ohm speakers plugged into the A and the B plugs. I've doublechecked the polarity of the connections. The DVD inputs audio over an optical line and video over component video lines. An older CD player inputs over regular audio lines. The receiver outputs video to the TV over component video lines. A VCR goes directly to the TV, so I presume it has no effect on the receiver. Final note: The only new thing in this setup is the receiver. All the components worked fine with a 20-year-old Yamaha receiver.
