Hello there !
I'm having a bit of trouble with my new TCL 55ep660, as I get a HDMI1 (or 2) popping up on the top right corner, the same you get when you switch from one source to another, except mine is showing for no apparent reason every couple of minutes.
There is only 2 devices connected to the TV, a RasperryPi that I use as a retro-console, and my computer from where I watch movies, series, online media... I also tried to troubleshot with threads I found online, like factory resetting the TV, disconnecting almost every features of the TV like Google assistant, swapping hdmi cables... With no success so far.
Any idea ?
