sound works it flashes a red white black screen of TCL home screen

55in TCL TV Roku. I turn the TV on the sound works it flashes a red white black screen of TCL home screen and then it goes off. I've tried resetting all these different codes. I need some repair. I tried the flashlight in the background black screen couldn't see a thing. Soundworks comes on for a second and then it disappears to a black screen. Repairable?
