Query: Defective

Apparently they're a very hit or miss company. The TV got here, we set it up, and then discovered that half the screen was non-functional. Called tech support and, what a surprise, it's a pre-order issue! Then we got the runaround from the company we bought it from. Generally a terrible experience, and unless I'm convinced otherwise, I'm not purchasing from Westinghouse or TigerDirect.com again.
