Thanks for that info iamrhumgod
Do you have an extra HDMI cord lying around? Mind swapping it out to see if the video still doesn't come up?
Looking forward to your response!

I didn’t mention it but yes I have swapped HDMI cables with no success. I also swapped component cables without success. I did swap HDMI to component converters as well (1.4 compliant), and same result. Pretty much confident it was something in an update that no longer supports 1.4 converters.
The 4670 was shipped (in 2019) with HDMI 2.0a support, which is backwards compatible with version 1.4. Since it works when you connect it to a display with HDMI in, then there's likely no issue with the Ultra itself. It's possible your HDMI-analog converter has suffered a failure of some type. If it has any adjustments (DIP switches or some such) you might see if you can try a different configuration.
I agree, the Roku works fine with HDMI but a second converter does not work either. I tried using different display settings on the Roku (auto, 1080p and 720p). No luck. The only other settings are 4K which won’t work with component.
The odd thing is, I can remove the HDMI from the Roku and hook it up to a DVD player and that works fine, so doesn’t seem to be the converter. That’s why I assumed an update removed support for the 1.4 protocol.
