Hi All, I have 3 Tivos in my house (Bolt, Roamio, Premiere). I went away on vacation last week and when I came back the two upstairs Tivos (Roamio, Premieire) were just showing blank screens. I was able to stream from both Tivos to the Bolt so I know they are functioning correcting. After troubleshooting for a long time, I figured out that the Premier would work if I used another HDMI input. The Roamio doesn't seem to output over another HDMI port. Is it possible that the Tivos somehow blew out my TV HDMI ports? It's an awful coincidence that this happened at the same time. There were a number of power outages in my area due to the heat so I'm thinking maybe there was some kind of surge. The Tivos are on surge protectors that were not tripped. Any suggestions would be greatly appreciated. PS- I'm trying to figure out what happened because if it is some kind of flaw with the Tivos I don't want to ruin all my limited HDMI ports.
