Sounds like you've done everything. When you tried the reset, did you hold the button in for a full 30+ seconds? Any less is not a true factory reset.
If you've done all that, and also tested it on a different TV (please try that as well), then it's certainly possible that it has failed. The Roku 4 is just over 4 years old, so it's really not ancient, but it's not unheard of for electronics to fail in that short amount of time.
