I am currently on my third Z9D 65inch in less than 3 months. The first lost half of the screen after a download update four days after the Geek Squad set it up. The second developed a horizontal white line about 2/3 from the top 10 days after it was delivered and set up. So far the 3rd is working great. This has a great picture when it is working. I have now met with several techs who came out and replaced my previous tvs. They had not seen the problems that I experienced. My first was plugged into a surge bar. The second into a battery backup surge protector. The techs thought that the download caused a problem in the first failure. The second was a chip failure. I asked what to replace it with if the third failed and they recommended the LG Oled series.
