My ROKU was purchased in 2017 and hasn’t been really used since then until now. I reside in a dormitory, and usually play my tv overnight to go to sleep. However, now it appears like the color is broken. It looks incredibly desaturated and the black tones and shadows are off. I messed with the settings, nope. I factory reset, nothing. I prayed, still nothing. Now, I’m just certain there’s an issue with the hardware... but I never dropped it or damaged it in any way. It just came out of nowhere! Are there any solutions? Or should I just buy a new TV.
Have you tried contacting your Roku TV manufacturer support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support for their products running the Roku OS.
