Hi, my Sharp LC52D92U finally packed it in after 12-13 years of great service. At the time I paid $4K -$5K for it. My budget for a replacement is way lower now. I'm looking a TV 55"-60" with a great picture and fast response rate. Reliability and longevity are also important. I don't care about the audio quality or "smart" capabilities. 4K seems to be the norm. Also should I go with a 2019 model...are they that much better?
