So, I've been away for a while, happily enjoying my 65X900E, but a recent issue has come up so here I am. While I am 99% certain it is a Comcast issue, I wanted to post here to see if anyone else is experiencing anything like this. Here goes...
I have an X1 TV box (non-4K) that I have set up to power down when not in use (power saving setting). Up until a few weeks ago or so (I don't recall exactly when it started), everything was working just fine. Now, almost every time I turn my system on (using a Harmony One), I get no picture on the Cable TV input. It appears there is a signal reaching the TV as it is a black screen (no audio though) and not the gray "No Signal" screen one normally gets. When I unplug the HDMI cable from the back of the X1 box and plug it back in, the picture appears and all is fine. To troubleshoot, I have swapped HDMI cables (no change), tried a different HDMI port on the TV (no change), plugged my Blu-ray and 4K players into the HDMI port that the X1 box was on (they both work fine), and have done the restart and refresh of the X1 box.
So, like I said, I think I have ruled out the TV and the issue is with the X1 box. Before I call them though (and go through that headache), I was just curious if anyone has experienced/is experiencing this with their Comcast box and, if so, what the solution was (if any) to fix it.
PS - still loving this TV almost a year after purchase!
