2 MONTH OLD TV

I HAVE TAKEN IN MY 2 MONTH OLD SAMSUNG 50'' LED TV WHICH I BOUGHT FROM GAME IN KIMBERLEY. THIS SPECIFIC TV WAS A DISPLAY UNIT & WAS SOLD TO ME WITHOUT A BOX. THE TV WAS INSTALLED AND PUT ON A WALL BRACKET AT MY HOUSE AND HAS BEEN WORKING 100% FINE UP UNTIL FRIDAY 24-04-2015, I THEN TOOK IT IN ON MONDAY 27-04-2015 BECAUSE IT WAS SWITCHING ON & OFF. I ALSO TOOK UTMOST PRECAUTION BECAUSE IT OBVIOUSLY COSTED ME A HELL OF ALOT OF MONEY. <br> <br> THEY CALL ME TODAY 28-04-2015 TO TELL ME THE TECHNICIAN SAYS THAT THE TV HAS A CRACK ON THE SCREEN ON THE INSIDE AND WILL NOT REPAIR IT AT ALL. MY QUESTION IS.... <br> <br> WHERE DID THE CRACK COME FROM ALL OF A SUDDEN!!!!?!?!?!?!?!?!?!?!?!?!
