TCL ROKU DIMMING ON AND OFF WHILE WATCHING TV/MOVIES
My TCL tv works great but one thing I noticed is when I am streaming or on spectrum App it tends to dim in and out on its on, it just started happening and it happens no matter what I am on.

That is most likely a hardware issue that you need to contact TCL about. Sounds like the backlight (all LCD TVs have some sort of backlighting) isn't working correctly.
Unless you're saying it's only happening with the Spectrum app/channel, in which case you need to contact Spectrum for help with their app. But I'm still inclined to believe it's hardware related.
