We can only hope that HK fixes the issues with this upcoming firmware update.
When having issues, does anyone consider the quality of their power? On my OLD HK, using Component video I would get what looked like old VCR tracking error across my screen. Drove me nuts until I found it was being caused by a dimmer in my next room. My AC would kick on and the pic and audio would drop out. During the day I would get wavy lines across the screen, the moment the area lights for the apartment grounds went on the lines would disappear. Being an electrician, I got permission to inspect, with a lineman from our local utility the Meter Main area of the electrical. The result was a faulty ground, and the neutral lug was loose.
So here are some things to consider besides the quality of the HDMI cables you are using.
Is your electrical system as whole properly grounded. i.e. is there a ground rod or "ufer" ground tied you your main panel. Are all the wires in your panel firmly screwed down, especially on the neutral buss?
What else is on the circuit that powers your HT equipment. Cheap CFL light bulbs, worn old dimmers, other cheap power supplies or transformers? Is there a section of your home that seems to "eat lightbulbs" where you are changing them every few months?
All these things create what is called a non-linear load on your electrical system. That is the sine wave of your alternating current coming from the utility no longer matches the sine wave going to ground. Poor grounding, loose or overloaded neutral wires cause a harmonic feedback that will find its way back into your electronics causing some strange things to occur. The National Guard built an entire data center building that was plagued with equipment problems (to the point of lawsuits flying back and forth) until it was discovered that is was a grounding issue.
When I install a a home theater, or computer room, for others, I strongly suggest a dedicated 20AMP dedicated equipment circuit. Additionally I ensure proper grounding of the entire electrical system (this is more important than just the outlet being grounded)
and strongly suggest a decent quality power filter, surge suppresser. Some home electronics have better filtering built into their power supplies than others, this you may find some things work great when others won't.
As a result significantly reduced callbacks, and happy customers.Hope this might help some who experiencing odd things with their equipment.
