I bought an LG OLED55C8PUA TV - a 55" TV. The picture is great but the sound is terrible so had to buy a sound bar.
Three years into use its WiFi module failed, which means it wouldn't connect to my WiFi. I had to pay $300 to have the module replaced.
The repair man, who has repaired many LG TVs in my city, told me that the new LG WiFi module part would, more-than-likely fail in three years too.
He also said I was lucky it lasted 3 years as his shop repairs many of their TVs in their first year of use.
Don't buy from LG.
