I have the LG WebOS TV UM7000PLA TV, it can't find my Super Nintendo via antenna cable.
Does the tv have an analog tuner and is it also selected?
Yes, both.
Is it possible to find a device via antenna cable without a receiver for cables and the corresponding input / output? Does SNES have other outputs for connection?
To be honest, no SNES, but I'm interested in myself.
Already a long time ago…
You don't actually have to search there…
Change TV to "analog". Then the console should be in the 30s programs (I even remember 36 or 39).
Possibly. Does this also help if you should need an antenna switch (which I do not assume)
My other TV (which is older) found it via an antenna cable and it has other connections but I don't have the cable for it.
As I wrote: station search is not, it has always been a fixed channel. The channel search will not find anything there.
Yes, digital / analog… If it would work, the switch would be too difficult for me. I would order an adapter on tv without scart connection to whatever connection, in the network. For example J ** m or W! Sh you get any format from adapter to mostly about 5 euro. Even cables from first generation consoles.
