Is there a list somewhere of the models this effects?
I have a TX-SR308 I purchased back in March 2010 and it's had issues after a couple years of ownership with audio and video.
Audio/Video cuts out on one or more HDMI ports, such as my new PS4(same problem occured when I had my previous PS3 system hooked up to it).
It's almost like a static style artifact and it only lasts a split second.
However, it continues to occur every few seconds until I turn off my receiver and give it a couple minutes before turning it back on.
Once back on, the issue is still present, but less frequent and it doesn't always happen. If I keep my receiver off for a few hours at least and try using it again, the problem is gone most of the time.
Using the HDMI connections directly from my devices to my HD TV, I don't have the same issue. I also have a TV antenna and a Super Nintendo hooked up to the receiver with no issues, so it appears to only happen with the HDMI ports on the Onkyo receiver. I've tried multiple types of HDMI cables to no avail.
Also, if I've left my receiver on for a certain period of time, let's say a few days, I'll occasionally have this issue where when I turn on my PS4/TV, the audio signal goes crazy and starts making these loud staticy popping sounds until I reset the receiver.
I attempted to enter my serial number on the website listed by OP, but it said my model does not need this update. Maybe my SR308 doesn't have networking built in and the warranty extension only works for models with networking? I don't know. All I know is I've been living with this issue for quite a while and only recently have I been in the market for a new receiver. I found this thread by happenstance so I was curious to see if my model qualifies. Is their customer service dept helpful at all?
Any assistance would be greatly appreciated. Thank you.
