My TCL Roku Tv is acting VERY weird.

My TCL Roku tv had a black screen, but I could still hear the remote inputs. I did a factory reset, and now when it powers on I see the TCL+Roku logo screen in full color and then it slowly fades to black. I still hear the remote inputs once it’s black, but nothing else.

Once I just left the tv on after doing another factory reset, and was able to see the Roku menu setup screen in full color, but then the remote was unresponsive except for the sound.

Here is the model.
