In the USA it's 800SAMSUNG to ask if there is such but unless you bought an extended warranty it's unlikely to be a maker covered issue. Let's see if we can find a LCD Panel to see how much to fix it.

The min shop charge is 150USD so 700 would be the usual repair charge.
I bought a new 50 inch for just over 300 so my bet is this will not be repaired.
