TCL TV: Status light on, TV off
Standby: the TV is connected to power and ready to use.
Applies to: TCL Roku TV models sold in the USA. What you see: colour not named by the maker, on steady.
What TCL says to do
TCL’s page gives no step for this state: it is what the TV normally does, or the meaning above is all it says.
TCL says the light can be kept off in standby on models that have the setting: Home > Settings > Standby LED (on some models under Settings > System > Power).
No repair advice of our own. The steps above are only TCL’s, as its page states them; semiatic gives no repair instructions of its own. Nothing here asks you to go inside the TV: anything beyond TCL’s own steps is a job for TCL Support Team.

The same colour and blink on another brand’s TV can mean something else.
