Hello all! My problem began when I got a new TV, my receiver did not work using HDMI, and reading some threads on this site, I realised that I had to update my 3806 firware. I have gone to: Denon Firmware/Changelog Download After entering the AVR-3806 - color black and serial number, the site returns the following message: The DVD players serial number could not be verified. Whats wrong? Or could anyone just send the update file to me pls? Thanks a lot!
