Most Mini-LED chip manufacturing is Taiwan and Germany (I believe)
But there are a lot of factories using those parts in China....
They all have tariffs. They are not as extreme as China. Goods from China will become totally unaffordable, also Vietnam and South Korea.
TVs will become a luxury, and few will be able to afford them, when their current ones fail.
One thing I fear is that violent break-ins will become common place to steal items like TVs and computers.
This is going to be an absolute mess. A lot of companies of audio gear will go under. Pretty sure Sound United will be among the first to go.
I think it would take us years to gear up to make TVs and complex audio gear here. Complex ICs will be a particular problem, but we don't even make caps and resistors here in any quantity.
My hunch is that for audio there will be a return to simpler two channel gear, but that is all hard to predict.
Once any member looses a vital piece of equipment from failure, there will be tough choices.
It would not hurt to buy a receiver now, as a spare, before the prices skyrocket or become unavailable.
