Friend lets more details, what LibreELEC image did you use?
It is possible to leave pictures of the electrical installation of the source connected wires.
How is LibreELEC behaving during this time?
I would like to use Atomic pi + TBS5520SE
Just to watch live TV.
Is the interface smooth?
Which remote control are you using?
4K does not work in my country.
Thank you
