Re: Roku TV Light under TCL logo at bottom of screen won't stop blinking
Hey - just had this problem and found a better solution worked instead of factory reset:
Bring up the "secret menu": press Home Button (5 times), then FF, Play, Rewind, Play, FF. From the new menu that appears, got to "Systems Operations Menu", the "Display Menu" and select "LED Brightness Menu".
I put the LED brightness to zero and the blinking no longer appears, though button presses from the remote do still appear faintly. Much better than losing all smart/internet functions just because I don't want to be constantly connected to the internet with it.
