I am very discouraged. We connected our new Roamio Ota and it was great until we started seeing static, snow, and a pink/purple tinted screen. Sometimes it goes back and forth between the purple picture and snow. I called tech support and after switching hdmi cables they said our unit was defective. Now I swapped out the old for the replacement thT was sent. And for about 30 minutes everything wa fin. Then it started again. I disconnected and reconnected the hdmi cable and the picture was good until I used the remote. Then the flashing between purple and snow began again. When I first turn the tv on, the picture is fine. I have no trouble until I use the remote. Then I can tab up and down with the volume control and get the picture to stabilize. Sometimes it takes awhile. This happens on live tv, recorded tv and streaming. Any ideas would be appreciated.
