Why does the power cord on my new Samsung Samart TV detach?

My old Samsung Plasma TV had the IEC connector as well and going for a better PC really improved the picture.

My new LG OLED TV's PC is captive so it might be because they don't draw much power compared to LED and Plasma TVs. The picture is great so no complaints here.

All the best,

One reason is in case you mount the TV on a wall and run the PC behind it.  You are supposed to use an aftermarket cord that's rated for that.  Not everyone does however.

It's so you can change the power cord to a better one.  It makes the green look more green, the yellows will really "pop", and Donald Trump will look a more natural shade of orange.

Because SAMSUNG SERVICE SUCKS, so it makes it easier for the technician to carry out the panel only. 😬
