I've owned my Roku Premiere + for some time. It was working fine early Christmas morning as it always has. We left later that morning to visit family and when I got back late, the Roku showed no signal. Nothing had changed on TV or Roku. I rebooted the Roku and got the splash screen then no signal again. I did a hard reset, same issue. Also, reset my TV to factory. Same thing. I also have a Amazon Fire TV and it works fine. Anything else to try?
I have the same issue with my brand new express. Worked great for like an hour, then midway thru a movie, it cut out, went to 'no signal' on my TV. Checked/made sure all cords were firmly attached, did a hard reset, left powered down for 24 hours....all, no results....just the splash screen then no signal.
