I have an older TCL and the thing has been an absolute champ. But today, the screen started going black ever 4-5 seconds for about a second then it comes back. Sound still plays. Only does it during streaming. Home screen is fine and antennae TV is fine. Connected wireles with a strong signal.
Reset internet
Reset internet connection
Made sure apps and system updated
Unplugged and cycled power
Only thing I didn't do was a full reset which I would like to avoid.
