I do have a high quality 5M Hdmi cable.</P><P>I convinced my self the new box was hanging because the HDMI circuits were less sensitive on the replacement box.I bought a Fibre Hdmi and it happens more often. I am powering off 3 or more times a day to watch Sky UHD. Sky diagnostics say the television is defective. None of the Four hdmi ports solve the problem. I can't seem to feed this back to Sky.
