I get the feeling. Depending on what, if any, troubleshooting you tried... (along with if the item was new,used,rebuilt,previously opened,etc.) it might have been bad batteries,bad contacts, bad remote,stuck power button, bad power cord, loose power connector, etc.. Or the Delivery Service dropped it and broke it. Could really happen with anything you buy.
If the price is right and you like a particular model... go for it. Just maybe look into getting it from a different source/delivery service. Might get you a TV from a different batch and delivery person... might have better luck.
