I used a 3 RCA to AV Input Adapater cable to connect my Wii to my 75” Hisense Roku tv. Every cable is connected where it should be but when I click onto the AV input, the audio seems to work but the video is the only thing that doesn’t seem to work.
I would suspect the adapter first. I assume it is a composite video to HDMI adapter? (Or if not, what is it?) Do you have a link to the adapter?

Oh interesting. I’ve never seen that particular style of adapter. Are you sure the TV has an input for that? I ask because the description is quite specific about TCL TVs.
Oh and I found these on the Amazon page:
“No it won’t work with Hisense televisions. This adapter was specifically designed to function with TCL branded TVs.”
And
“I tried it with a Hisense U8H tv --it DOES NOT WORK.
The Hisense tv uses a plug about 1/8 inch longer than this one (enough for another ring but has a double-wide ring at the base) and is wired differently. It was harder to locate one made for Hisense.”
