Advertisements I had the BOX CLOSED (cover still on), when I saw the INTERNAL blue light. On the lowest level Roamio, the cover is black, but also slightly translucent. So with the lights dim in the room, and no front lights on, that internal blue light is actually very noticeable. (though only on when the "problem" occurs) As for your "no harm came of that" scenario, that was exactly what I wanted to know. So as a last resort, I'll consider trying that. If anyone else has knowledge/facts/test that they have done that will help, please let me know. -thanks!
