Here is blog post: https://hifiaudios.com/tv/tcl-tv-backlight-not-working/ We’ll start with the basics: what to do when your TCL TV turns on but the screen stays black, when only half the screen lights up, or when the backlight flashes and flickers.

I’ll show you how a simple power cycle, cable check, or reset can bring your TCL display back to life. You’ll also learn how to test your TV using the flashlight method, what to do if you see white spots or bright dots, and how to fix a TCL TV that’s getting dimmer over time.
