Very disappointed with the whole affair

I set this TV up per the instructions. I turned it on and got a picture. I turned it off and back on again and got nothing but sound, no picture. I reviewed the manual for trouble shooting problems without result. I then called Samsung and was told they would contact a repair service to come out and fix my TV. Fix my TV? I didn't have it for more that four hours. I didn't want a refurbished TV! I explained my position to Samsung. Their response was that they could only have it repaired not replaced. Very disappointed with the whole affair. Sent it back!
