Theoretically, the repair won't cost you anything if it's covered by the set's warranty. However, warranties generally require you to deliver the set to a repair facility. A home visit would be extra.
Unfortunately, Samsung doesn't have a great reputation for prompt, effective action on a warranty claim. You're better off with the store's separate warranty, which may be an extra expense when you buy the TV but you can count on it better.
The good news: your set most likely has a fairly simple power supply problem that will be easy to diagnose and repair without a huge cost. But you'll save big money by taking it into the shop.
