Problem setting up using HDMI to component adapter

I have the Roku Express Model 3930CA.  I want to connect it to a 20-year-old rear-projection TV.  The TV has no HDMI so I want to use an HDMI to Component adapter.  When I connected everything, the screen looked like this:

 

I can recognize the screen but it's unviewable.  Because I couldn't set Roku up on the TV, I connected it to my computer monitor because it has an HDMI port.  When the system sent me an activation email, I had a problem.  My only computer with email is my desktop which I disconnected from the monitor so I could setup the Roku.  When I clicked "Activate", the Roku wasn't connected at that moment and I think the account didn't activate.

I want to setup the Roku on the TV so I hope someone can suggest what is causing the problem in the image.  And suggest a solution.

    Component or composite?

    Try swapping the cables around  Does the converter have a NTSC/PAL switch?  Can you post a link to the converter and the model number of the TV?

      Yeah, that image doesn't look like the correct refresh rate, and if it's set to PAL that could be the cause. Also be aware that your TV very likely doesn't support 1080p (most all of those old rear projection sets supported 1080i). If the TV doesn't support 720p (again, some from that era only support 1080i or 575p in a digital connection) you might simply be out of luck getting the correct display.

      Many of those old sets had a DVI input, and a simple DVI to HDMI adapter cable will work. But again, the TV would have to support 720p in the DVI input (DVI is digital, just like HDMI, just no audio path). No Roku device available that is still supported (other than the Express+ 3710/3910) has the ability to output an analog signal. And frankly an SD analog signal probably isn't going to look very good on that set.

        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.

      As you'll see, the adapter was very basic.  No NTSC/PAL switch.  Not much to adjust at all.  You just connect everything and it works or doesn't.  I contacted the vendor who responded promptly but said he didn't know what was wrong.

      For the rest, here's a link to the adapter on the Amazon Canada site.

        The device seems to do everything automatically, but I wonder if Roku sends it a 1080p signal, can it figure out that your TV may only do 1080i?  I’m not sure how well something like that works between an automatic gadget and a 20 year-old TV.  Have you been able to see enough of a UI to try 720p?
