I've had an Onkyo TX-NR809 receiver since Jan 2012 and it has always performed flawlessly. On Saturday it arbitrarily started showing green graphical glitches but only when the input was set to CBL/SAT for Sky TV. I initially suspected the Sky box was at fault because the issue was not visible on other inputs, but I've now performed a variety of tests that seem to show that Onkyo receiver has developed a problem processing 1080i inputs (Sky+'s max output is 1080i). If I toggle any source's input to 1080i I get the same glitches on the screen, but 720p and 1080p are fine.
I've tried lots of things to narrow down the problem, including connecting 1080i sources direct to the TV (no green glitches), replacing the cables (no difference), and even tried a different telly (problem persists) but all things point to the Onkyo being at fault.
Here's a quick video of me toggling the YouView box from 1080p to 1080i and the resulting display problems:
I tried contacting Onkyo customer support (I was surprised to be pointed to a Pioneer site), who weren't very helpful and just pointed me at the authorised repair centres.
Anyone else had similar problems? I've seen lots of reports of failed HDMI boards but nothing quite like this.
Do you think this is failing capacitors on the HDMI board?
Anyone have experience of GenServer or Babber repair agents in the UK?
Finally, I spotted the 809 recall from March 2012 and there's a good chance mines affected. I've not been able to find any current info on it? Anyone know more?
Any help appreciated!
