DVDO Edge (non-green) failure

[HDgaming42]

Question for the other owners out there:

If your unit has failed, what symptoms did it exhibit before it died? I'm aware that the power supply is known to die a premature death (have the part # bookmarked for such an occasion) but it seems mine went another route.

First I lost HDMI 5. Thought it might have been from hot-plugging something and blamed myself.

More recently it was showing a white line at the top of the screen that would come and go. The picture would shift up and down, across multiple inputs.

Then it became temperamental with certain sources that would work fine direct to the TV.

I had to keep power-cycling (input switching no longer worked) the unit to finish watching a movie.

This evening it refuses to show any sources on any inputs. I can bring up the GUI just fine. I enter safe mode (guide button) and it doesn't resolve. Every input and source is "unsupported format". Interestingly enough if I bring up the 1/2 and 1/2 test patterns (the ones over a video source), the "video" side is scrambled green pixels. (Otherwise the inputs show a blue screen)

I re-flashed the newest firmware without any change in behaviour.

Has anyone else seen an Edge die like this? Anything else I could try?

Edit: all my cables are "Redmere".
