Not sure why the Yamaha download is not working directly from your 3900 but you can download it from here on your PC:
http://usa.yamaha.com/products/audio..._u/?mode=model
Click "Support" at the bottom of the page. The 1.18 download link and USB installation instructions are on that next page. You will need a Yamaha Easypass account. It will let you create one if you don't have one.














In 35 years I have owned seperates,SS and tubes. For a AVR in this price range it is a good one with clean amps. I have R2R and TT, it plays "Straight Analog" great (Burr brown DAC)has a warm tone to it for SS pre/amp and amps.(no processor)
sold it for parts. I think the 4600 is not a HD model like the 1900/3900 different chassic etc... Have you had the main fuse looked at inside? Spikes in your supply from wall at night or a storm or who knows.Maybe You just got a lemmon...... how old is the 4600? I had to Google the Yamaha Factory site to look at specs on it. And I thought I knew a lot about Yamaha AVR's
