I can't count the number of times I have been misled by something like this. For example, you change one cable to fix a problem in another and while you are changing it, you accidentally bump the other one, fixing a bad ground connection that was actually causing the problem. Result: You incorrectly conclude that the cable you changed was the problem, when it was actually the cable you bumped. I'm not saying that is what happened in your case, just that I have experienced similar things more than once. Usually it happens to me when I am trying to diagnose something much more complex and I end up wasting days pursuing a phantom.

It was definitely the HDMI connection that was causing the drop out of RF signal in my case.  HDMI is hot plugable so I could see the signal strength change every time I plugged it in or unplugged it... if it was a case of knocking the RF to fix it I wouldn't have got the consistent results I did.  I originally thought the RF socket was faulty until I researched it and read about the HDMI signal issue others were having.  It was probably a grounding issue due to bad design or something but I had to try several HDMI cables to find one that worked ok... the cheapest in this case worked the best.  I did then try swapping the HDMI cables again and was able to consistently replicate the issue.
