HDMI to RCA Adapter Questions

[Turkesh]

I'm trying to use my Roku premiere on an older television with no HDMI port.
I bought this converter: https://www.amazon.com/gp/product/B0779KKKG4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I am getting no display. I checked to make sure the cables work, the Roku works on a separate television with HDMI cables. I tried multiple AV cables.
The issue seems to be the converter but I thought I'd ask here before I do anything else.
Any thoughts appreciated

Verify. You are plugging the Roku into the adapter and then running the RCA cables to the older television - is that correct?

How are you powering the adapter?

Are you sure that you have the correct standard selected (PAL or NTSC)?

There's better way to do it - Roku with analogue output

Yes, I have an HDMI cable from the Roku to the adapter then RCA into the older TV.
I didn't realize the adapter needed to be powered. How should I do this?

In the Amazon link that you provided the second to last image at the bottom shows a small port on the side of the adapter.

The port is labeled USB/Power.

The top image shows three cables. The rightmost being what appears to be cable you would used to power the adapter via a USB port. Unlikely that you have a USB port on the older TV.

You would need to find or purchase a USB power supply via a wall outlet to provide power to the adapter.

Ok, I'll try that and if not I'll just purchase the Roku suggested by Alabalcho. Thank you both for all your help!
