As it happens, the TV has the DVI port and I had an HDMI>>Component adapter plug. But the screen image was just as bad. I didn't take a picture but everything was blurry and out of focus so that I could only guess what the buttons on the Setup screen actually said. And that's why I used my computer monitor instead.
For this TV, it's only being used to watch movies on DVDs. An SD image will still be better than what I've seen so far. There is another adapter I was looking at on Amazon but, not knowing what the current problem is, I didn't want to buy it.

OK, I would have expected a product like that to work. Remember that when the HDMI is converted to component, you now have an analog signal, not digital. The DVI connection remains in the digital realm, so what's likely happening there is the Roku is sending a 1080p signal and the TV can't process it. The analog/component connection should not have that issue, but for whatever reason the TV isn't processing it. And my guess is it's the TV's issue, not the converter.
I was able to find a manual online, and it confirmed what I feared. The DVI connection only supports 1080i and 480p, and the Roku doesn't support either resolution. Why the component converter isn't working I can't say. But my guess is it can't properly convert the Roku signal correctly.
The first adapter has been returned. One comment on the product page was that it doesn't permit scaling of the image. The other adapter, linked in my previous message, does scale.
Since returning the item is an option if it doesn't work, I'm thinking it might be worth a try.
hey david, i had the same problem when trying to connect an HDMI only cable box to an old projection tv. i ended up not being able to use the tv after going through 2 hdmi to component converters. i did get it to work on another old tube tv at one point. but i am trying to do what you're doing now. i have a roku express+ that i have connected to a very old tv using just AV out, but the picture quality is not great. it has 1080i capability. i just tried using the 2 converters in this case, but actually got the same results you did too. i might play around a little more to see if i can get it to work. i'll let you know if i do. i hope you'll post if you get yours to work or another solution.
i was actually wondering if roku made a device with component output. haven't found one yet, but if anybody knows...
This is a handy page for finding out about past and present Roku models:
https://en.wikipedia.org/wiki/Roku
The only Rokus I see with component came out in 2009 and 2010 and they were last updated to Roku OS 3.1. (12 is the current version.) I would not recommend bothering to find one of these. They probably do very little if anything today.
