XG1V4 box HDMI handshake problem

I have seen several messages/questions in this forum about problems with the XG1V4 box losing its HDMI connection with the TV. But in none of those threads does there appear to be a resolution, so I am going to try to bring up the question/problem again.

 

My setup:

XG1V4 connected via UHD high-speed HDMI cable to Samsung UN65JU6500 TV.

 

Problem:

The TV and XG1V4 work fine together for the whole day. Then, the next morning, when I turn the TV on I get a black screen. I can resolve the problem by rebooting the XG1V4 (obviously not an acceptable way of dealing with the problem). Occassionally, without needing to reboot, I can get the box and the TV to communicate correctly by first connecting the XG1V4 to a much older non-UHD Samsung TV, getting that TV to show correctly, and then connecting the XG1V4 to the UN65JU6500. But that doesn't always work. In any event, even when I do get it to work correctly, it quits working again the next morning. Rinse and repeat.

 

Elsewhere on these forums there have been a couple of suggested fixes. First, turn off PowerSave. I have done that. Second, make sure you have a UHD high-speed cable. I have done that.  Third, make sure that you have the latest firmware on the TV and on the XG1V4 box. I have done that.

 

From reading the various threads on this issue, it appears that it is an HDCP 2.2 issue that is causing the XG1V4 and the TV to have a problem establishing an HDMI handshake. And several Comcast employees suggested that the problem has been sent back to the tech folks to find a solution. But unless I have missed it, I don't see any notice of a resolution.....
