This is the first time that I am hearing about Edge hardware failures. You should have started your own thread on this so that it would get more attention.Box 3 has arrive and is up and running. It did not crash on boot like box 1&2 but did reboot all of a sudden about an hour after finishing setting it up.
One thing I noticed right away is the picture is much better than on box 2. Much sharper and way less noise. Box 2 was blurry and prone to macro blocking.
We may have a winner here.
