Thank you very much for answer here, I checked PM and do not received any message from you.
That's very bad news for me that even autorized Onkyo service in USA couldn't repair that
does they told you maybe what could cause this problem ?
I'm 100% sure that's not my network problem I used this network always same configuration for about 4 years till now without any problems, all other my devices work perfect from this network, TV, HTPC, PS3, X360 they are all see my DLNA server.
USB port also don't work, when I insert pendrive nothing happen only solid light from it, should blink when is inserted when checking it/reading, of course I tried with all my pendrives of course they are formated to FAT32 as always.
I upload video with that problem.
I checked firmware versions from dispaly and looks like it miss firmware for Net because shows "?"
but of course that could be not only firmware issue.
Main 9....1.08 / 08223A
HDMI......1.01 / 07706A
I will try to send it for repair in authorized Onkyo service in Poland, and let you know what they will tell me doing diagnostic. I will send it after new year, because now they have a lot of work and recomended me to send later.
If my unit also they will can't fix this I think I will have to find some external USB/Network player which have some small display, because for music listening I don't want to use also TV. Maybe you know any good models like this ?
Thanks again for answer!
Ohh and forgot to say, about this Factory reset, I also was confused when display shows me "Net Clear skip [ent] not pure Clear and then I have to confirm that by Enter button then show Clear. I asked them in service and they told me that's correct for that model, even more they send me a video to confirm this.
But this kind of reset is for me bad, because looks like it not clear Network settings at all, it skips them.
After this factory reset when I enter to Server or iRadio I see on right side of list white bars which they are in different level which look like they stay there when was correct connection with internet and shows list for example with my iRadio stations.
