Well i have my second 4k hdr tv ( tried a diffent brand to confirm the problem is with comcast) now and when i turn on in the morning i get the "no signal" message. Tried changing channel and changing input but still wont hdmi handshake w comcast xfinity box. Have to go through the lengthy comcast box pull the power to force a reset and wait 5 minutes for the box to come back up. This is ridiculus that a problem has remained unsolved for so long. Calling tech support is a joke. Im an electrical engineer and it is so frustrating tryi g to co.municate with their helpdesk. Please come up with a software update to correct this.
