Query: Buyer Beware

Too bad I didn't research this product before shelling out $400 at Best Buy. It died after 5 weeks. I can't return it to Best Buy after thirty days. I went three weeks before Samsung replaced the motherboard. It failed again. We haven't had a television again for 3 weeks. Now Samsung says it needs another motherboard. Samsung won't replace it, or say that it's unfixable. I don't want it replaced with the same television even if that were an option. I've never had a root canal (as one reviewer wrote), but it might be better option than what I have gone through.
