I have been at Suvarnabhumi International Airport (BKK) many, many times and there are always hundreds of visitors - many look to me to be from India - each with at least one LED TV, some have more than one! I see them in the check-in area and at the VAT refund area. I see them getting out of taxis curb-side with TVs, so I assume they buy them in town, and then get the VAT refund ( 7 % ). I think I have seen like 10,000 LED TVs at the airport!

I am not familiar with the AC power in India, you'll have to verify that, a notebook PC should have a 50/60 -120-240 brick. My Samsung LED TV purchased here in Thailand, says 50/60 Hz - 115-240 V on the back. My Samsung DVD player, purchased here, also says it supports 50/60 Hz, 110-240 V.

I doubt the warranty will be any good in India.

I do not know what, if any, import duty you will have to pay when arriving in India?
