Beware of Poor Warranty Service

The set is excellent when it was working but warranty service is pathetic. 3 months old and it started to have a totally white screen upon start up. Filed a warranty claim online, pickup was prompt by a repair vendor that Samsung directed me to. That was 5 weeks ago with no end in sight. The authorized repair vendor keeps saying they are waiting for parts, every time it's different and every time the part is special order from Samsung. Samsung 800# is useless, the escalation line has been down for a week, all you get is no help and a hang up. At this point, I really don't think I'll ever see the set again. Total frustration. Beware!
