Query: Great TV but unreliable

This unit was I thought for the first two months a great bargin. Then it started recyling at turn on, then refused to turn on at all. All I got was a black screen and a blue light. Contacted Samsung and they said I needed service. Service never called or showed for appointment. Now I have a different service provider, TV has been down over a week and will be at least another one. Samsung is trying but In my over 60 years I never had a TV go out within 55 daysof delivery.
