55" TCL Roku YN00C2624937 Activated on 12/4/2019
TV has message about overheating.
TV is mounted on swing arm away from wall with nothing around it. Room is 66 degrees Fahrenheit.
Unplugged and plugged back in several times after waiting several hours "to cool down".
Once plugged back in, TV turns on with same overheating message appearing.
About 15 seconds later the TV screen shuts off.
Any suggestions out there on a fix?
