Panasonic professional displays are sold and used widely across the US. Panasonic just has lousy international marketing and sales capability. They don't know how to operate here.
I am on my second Samsung display. My first one, a 8000 series TV from around 2010 or so, is still working fine, but was replaced a couple of years ago by a 85" Samsung LCD.
So far, no issues.
LG is not one bit better with a swath of failures for similar reasons. Capacitors popping and bringing the whole TV down. I wouldn't recommend a LG TV for years, but they do seem to have slightly improved.
All these manufacturers, in recent years, seem to be pretty much in line in terms of failure rates. It's very low, but it is always those failures which bring out a very vocal crowd.
Frankly, I would like a 80"+ OLED at some point in the future, but I may opt for a 900 series Sony.
