I just got this Philips TX (I believe 12B710) and i’m looking for a port to connect something like a converter to AV, problem is that I have 0 clue to what this port could be. I read somewhere coaxial but i’m not sure.

Also, are there any adapters that can switch from a av input to hdmi input? I want to connect some old consoles on it but it would be a bummer to also have to buy an hmdi converter separately.
