la sirena and plaza lama offer guarantees. maybe try those.
Skip PLaza Lama. They sell the worst crap you can find. Some of it refurbished and sold as new.
Maybe best buy one from USA.
You're kidding right?? Try taking back a TV you bought in the states after 6 months of ownership and see what happens.. Warrantee's on any electronics are a thing of the past unless you PAY for the extended warrantee and even then it's only good for a year.
