wow... abes of maine REALLY pushes hard to sell their overpriced accessories... Today (ordered the T.V. last night) I got a call from Abes of Maine saying that the buzzing is because of an issue with the electricity and that I need a good surge protector bla bla bla. And then he said "I need to upgrade my shipping because the 'free shipping' will not wait while I inspect the unit". In fact he said once the item has been opened, it CANNOT be returned. If I got a bad unit, I'm SOL.... wow abes of maine... it does NOT reflect the reputation I've read!!!!
