My Roku Ultra 4670 stopped working on my older HDMI to Component converter which is connected through a Harman Kardon AVR 320 receiver to my Mitsubishi DiamondScan 65" projection TV. The converter supports HDCP 1.4 and below, so not sure if an update forces a newer version of the HDCP protocol? I get audio but no video.
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.
Welcome iamrhumgod
It looks like you have an issue with the Roku Ultra that is not working with the HDMI converter.
Have you tried connecting the Roku Ultra directly to the Projection TV or another TV to see if the issue persists or if you notice any difference?
Let me know how it goes!

I skipped the receiver and went straight to the component connections from the converter. Still no video. I tried it on another straight HDMI connected TV and it works fine.
