The LED strips are somewhat replaceable - you should be able to find them on either eBay, AliExpress or ShopJimmy. I will warn you however that it's quite an involved process - I know a fair few people who have managed to crack their LCDs or rip ribbon cables in the process of trying to fix backlights. Unfortunately it seems that backlight issues are becoming more and more common - especially as most sets have a "Dynamic" mode or similar which sets the backlights to full brightness and drastically shortens their lives.
