For me Samsung were TERRIBLE. I have 4 of their TV's, all of them have failed, the last one being my 8000 series that had to have a new screen. I am glad I bought it via Richer Sounds as they made the pain go away, but Samsung for me were disgraceful. I won't buy another of their TV's even if they are the best on the planet according to every review on the plant.
One call and I had a panel delivered within 5 days. Service was fantastic for me no complaints at all.
