Best Buy review: 75-inch sony bravia oled - not working

Has anyone else purchased a 75-inch Sony Bravia OLED from Best Buy only to have it die early? I bought this TV for $2,899.00, and it completely stopped working after just a year and a half. I unfortunately didn't purchase the extended warranty, which I deeply regret now, though it's hard to say if Best Buy would have replaced it anyway. Still, for a premium $3k television, you expect it to last much longer than 18 months. Incredibly disappointed.
