I had my ks8000 for 2 years before it hit the dreaded green lines which seem to be common on Reddit. 1500 dollar top of the line TV that hardly lasted.

Luckily, Samsung was awesome about it and I was able to RMA through Best Buy, who just gave me my money back. I took that cash, put a bit on top, and bought an LG OLED. Best decision ever. OLED is absolutely dominant in TVs these days.
