Query: Samsung ext Warranty worthless

I own a Samsung LN52A650 Touch of Color I bought 18 months ago with the extended warranty. My power supply just went. What they do not tell you is that they only ship parts by ground after the first 12 months. It will take about two weeks before the service dealer gets the part to replace it. Customer service for Samsung is very below average. I will go back to Sony
