My AVR-X4000 started acting oddly intermittently a month or so ago, and has progressively worsened. After sitting powered off in Standby a few hours, it becomes unresponsive to Web control and sometimes unresponsive to even the infrared remote control. By unresponsive, I mean that I cannot get the Web Control to connect in order to power on any zone. If I manually power it on with the front panel switch, the network function is frozen, i.e., I can't select a network source such as internet radio or my NAS.
If I disconnect the AC cord for at least 10 seconds and then reconnect, everything resets and works fine. I have tried numerous microprocessor resets and network resets (per post #5
). These also normally work tor restore functionality, and I then reload my config.dat file with all my settings. However, yesterday I did a network reset and the loading of the config.dat file was unsuccessful. I had to manually reconfigure everything.
I sent a request for assistance to Denon Customer Support 2 days ago and still have not received anything beyond an automatic acknowledgement of my request. Needless to say, I am not impressed with their service.
Has anyone here had the same problem? I am thinking that Denon has continuing issues with their networked components. I also own an AVR-3310CI with a network card that stopped working a few months out of warranty; from my research on forums like this, failed network cards seemed to be a fairly common problem on that generation of receivers. Does the X4000 have a replaceable network card like the 3310? Thanks in advance for any help.
Update: As of January 20, I still have not received a specific response to my questions from Denon. However, I decided 2 days ago to take JD's signature block suggestion to heart and I did 5 network/microprocessor reboots in a row, then uploaded my configuration file. Jackpot! The receiver has behaved like new ever since, with no lockups or unresponsiveness. I'm keeping my fingers crossed that it lasts so I won't have to send in the unit for warranty work. Thanks, JD!
