Well, after listening to yet another Amazon CSR vociferously misinterpret the documentation provided for this TV (and again refuse to accept its return), I've gone ahead and disputed the charge on my credit card. The credit card company's instructions to Amazon are to arrange for return of the set or provide proof that it works as advertised. I've already got documentation from Syntax that says the documentation is wrong, so I'm pretty sure this will be a slam dunk.

Of course it's an Amazon issue. The vendor has an implied warranty that the product work as specified and advertised, at least in my home state. On-line, catalog and mail purchases are qualified as "local" purchases, so Maine consumer protection statutes apply.

I didn't give my money to Syntax, I gave it to Amazon. If they're going to act as a sales agent for a product, they're expected to handle issues caused by their misrepresentation of that product's features.
