I purchased a 60 inch Samsung 4k tv. The tv failed to function in less than 3 years. Horrible brand.
I’ve been using the same 32" 720p samsung TV since 2006 in a bedroom of mine. That TV is now 12 years old. My best friend bought the same TV and it’s still running for him also. I’ve used it as a monitor for years and it’s easily had 29k hours of images on it’s screen without a single hiccup. I’ve gone through no fewer than 4 TVs in my living room including 2 Sonys in that time span. I really don’t think your story is detailed enough to damn an entire brand.
