I'm not quite sure. Variables for plug outlets, wattage, tuner specifications and other options can vary from region to region.
I have no way of determining compatibility for other countries.
Recently, I've bought Samsung UN40C6300 LED 40" TV from US and I'm planning to use it in India.
Other than step down converter and digital set top box receiver (HD), what else I will have to take care in order to have this TV working in india?
