Both of my Roku TVs have red/orange washed out video
This issue just started today. I have been troubleshooting on my TCL 43" Roku TV. My RCA 32" Roku TV has the exact same behavior.
All Roku channels, once video starts, turn grainy/garbled, and only show orange/red colors.
All HDMI ports on both tvs behave the same as the video channels.
All text, menus, preview screens, icons, are as clear and clean as ever.
No settings have been changed prior to this issue. Both tvs started this behavior at the same time. Roughly 4 hours ago, I watched a 1:30 length concert on the YouTube Roku app without any issues. Crisp, clear video.
I'm including pictures of a couple of moments in a Simpsons episode on Disney+. The same picture distortion is displayed by every Roku channel, from Hulu to Netflix to HBOMax.
Have you tried contacting the TV manufacturer to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
