rca projection 40 inch

Both sides of the screen about 6 inches in is a different color (lighter) than the rest. I contacted rca and they said it could be burned screen. I do not know how this could be it is 1 year old, one week left on the warranty. If it is burned I will have to pay, the repair firm want 200 dollars to come here and I would have to pay if burned. The entire 6 inches is different. I have never done any thing to this tv except turn it on and off.
