Hopefully (and very much so), it's just the power circuit (most likely the transformer) which is blown
one easy way to test that possibility is to test the resistance between the AC terminal connectors (since a blown primary coil is the most likely culprit)
if it is infinite, the issue is very likely a blown tfr whicih can fairly easily and chaply be replaced

kaboom as in actually heard or something? or smell something from it?
make sure u read the power ratings written on it and if it says 110V only or both 110 and 220.
If u indeed heard something or smell something, then you probably blew a cap or worse blew the power circuitry, if its a cap, its easily repairable, the circuit on the other hand depends on the extent of damage. So assess the above and post back ur observation. make sure you try checking the resistance between the terminals as superczar suggested above if u have access to a multimeter
I did the same a long time back with an old amplifier (which had a big sticker on the power plug saying '110 volts', the booze did really get to me that day 
). The transformers were fine but the fuse was blown, along with a couple of caps in the power supply, and half of the output stage. Didn't cost me too much, and after a new pair of transformers wound for the correct voltage, we were back in business. Took a couple of thousand bucks, all told.
Another friend bought a Bose acoustimass from the US and plugged it in straight. All the power chips split into half down the middle, and the inside looked like an atom bomb had hit it. Basically unrepairable, but seeing that it was a Bose it was probably better like that.
It kind of depends on what protection circuitry was built in, and the topology of the amps. Chips will be blown clean off as the voltage is twice what they are rated for. Even protection circuits cannot account for this much operation out of spec.
If you're very lucky it's just a fuse. If you're unlucky...

its rated only 110 volts
i dont have access to a multimeter unfortunately.
Can any one from Hyderabad tel me where get it repaired.
try globus at ctc, or i guess its called globus, am not sure about the name, its very popular there, on the first floor, big office, its either in the main building or the one next to it which has the samsung service center in it
