Roku 4 working fine, connection to internet via hard wired, and then it just returned to the ROKU main display, then nothing worked, stays there about 10 seconds then displays screen that it cannot connect to HDMI device. Reset unit and same results. Unit has always run very HOT to touch and I figure it has finally cooked the electronics inside. Unplugged and let cool for an hour, since the unit is always on and that also made no difference.
Anybody have any ideas or is the unit DOA? as I suspect. It only last about 2 years.
