Help! I set up my system for the first time last night and was able to power up the receiver and run a few successful YPAO auto calibrations. Next, I put a DVD in my new DVD player and was able to see the picture, but there was no sound. I did hear sound from the speakers during the calibration and I also heard sound from a channel via my satellite receiver - amp/receiver connection earlier. Suddenly, the unit powered down. When I powered it up again, there was a quick message saying something about "check speaker cable connections" and shut off again. I went ahead at that point, kept the unit off, and went to bed for the night. When I awoke this morning, I checked the back of the receiver and indeed 2 speaker wires had come loose. I took them out, twisted the wire slightly, then put them back into the receivers connector, and retightened using the Yamaha wrench. After doing this, my receiver is still not powering up. Do any of you have any ideas on what I could be doing wrong? The receiver is new and could possibly be defective, but I am so new to this HT stuff, I very well could be doing something wrong. Any advice would be much appreciated. As an additional comment, the receiver did not seem to have a "natural" hole for me to stick the wire in. I mean, the sound was working earlier, so this may just be my perception, but the Axiom speakers had a much easier post to attach the wires to. I look forward to your help. Thanks gang!
