I'm still not able to get my TV working, in spite of doing everything on here. I plugged my Roku Streaming Stick + into an empty HDMI port on my TCL Roku TV, to see if that would work, since the stick hasn't been updated.
For some reason, the TV doesn't recognize the Roku Stick. Is it impossible to use a Roku stick with a Roku TV? The only HDMI thing the TV recognizes is the Bluray player, but the Bluray player doesn't have any HDMI ports, so I can't try running it through the Bluray player, only from the ports on the TV.
