Nothing is wrong with South Korea or Japan.
I think Panasonic makes some of the best electronic consumer equipment you can buy. I have a 42” Panasonic Plasma TV that will not die. It still has a great picture.
I have a Samsung 32” TV that is average quality.
I was discouraged by salesmen at Lowes NOT to buy Samsung appliances. That they have the most problems. I bought Whirlpool/KitchenAid/Amana/Maytag instead. They are still made in Iowa.
I have never owned any LG products.
LG makes good appliances even under the Kenmore brand. Samsung makes good TV’s but their refrigerators tend to break after a couple of years(they get leaks in their compressors and/or the heat exchanger/evaporative tubing). Samsung’s phones are good. The Samsung stoves and laundry equipment are built like tanks but are also uber expensive.
