Hi Mark I did two resets and nothing. Even with great picture with hdmi could it still be hdmi failure? I did try an update via Ethernet and it said it was up to date. Tuner has audio though, but no audio for streaming music via Ethernet.
So either the DAC or HDMI board is caput. I see that is a seven year old receiver. Unfortunately that is within the normal life span of receivers. Too often it is less. As you know I find them problematic affairs. It is too bad that is the way the industry has been geared for so long. It is not sensible and certainly not elegant design. I would love to see research done on the fatality time curve of these things. No one has done one. My intuition tells me it would be a shocker.
As you know I'm not a supporter of a lot that comes out of the EEC. They have mooted the idea of doing this, and writing longevity requirements into law, with heavy fines for manufacturers that fail to meet reliability targets. Not only is this sort of thing bad for the consumer, but it is a massive hidden pollution problem. Not so hidden now, as more and more third world countries are refusing to accept this junk. Some are starting to send the stuff back to the country of origin. The UK is getting some big piles of this junk and have no clue what to do with it.
I certainly think these options should be considered.
Collecting the TRUE cost of disposal at the time of purchase. Some of this is starting.
Preventing obsolescence and mandating modular designs that can be upgraded that would reduce the volume of this waste.
Definite rules for acceptable longevity and reliability.
This is a growing problem we don't talk about enough here. I'm suspicious the problem has been worsening the last few years, with the proliferation of Atmos receivers.
I have just seen your last post. I think you will have to think carefully about the wisdom, of a potentially very costly, repair on a seven your old receiver. Just the physical act of repair will set you up for the chance of further repairs.
