So I have a question for TCL roku tv owners, I tried playing my original Xbox on my 55” class 5 series so it’s a model that doesn’t have AV ports but an adapter, I tried using my adapter that came with my Samsung tv awhile back, it fits perfectly but doesn’t get signal, I see some on Amazon that specifically say adapter for TCL TVs, are these the only ones that will work on TCL Televisions?
We need more information - what are the inputs to the adapter, and what are the outputs?
