TCL No Backlight, Black Screen, Flashlight Test Good, Menu Sounds Good

TCL No Backlight, Black Screen, Flashlight Test Good, Menu Sounds Good I have a 55” TCL Roku TV (55S405TNAA) that was working fine, then the next time it was turned on has no picture. Clicks are audible when adjusting the volume or navigating the menu. Flashlight test does show the menu.

@kzoomarine check your power board first. Test the LED output connector with a voltmeter and let us know what you get. It could be the power board. If it checks out ok…….well I am not going to say it but you know what it most likely will be.
