Query: Short term quality

We purchased this tv thru Amazon 2years ago. The delivery service and set up was excellent. The tv had a beautiful picture and good sound. We were completely satisfied - UNTIL NOW. There is sound but just a black screen. After searching the internet for a possible fix, we found this to be a common problem with this model. The Samsung service rep that called us was rude and short. We are in the same metro area as his shop but he was going to charge us a $35 out-of-town fee plus mileage. We are having difficulty finding someone else to work on this tv.From reading reviews on Amazon and searching other blogs it sounds as if Samsung is not the brand to go with, especially this model.Please be aware that we have received nothing but excellent service from Amazon.
