Well, if it is an NTSC TV, it will not work in India and if it is a 110V power supply you will need a step-down transformer (adaptor) to use it over there. VCR/DVD players have the same problem, but the main advantage is that if you buy a TV now a days in India, most of them are Multi-System which play all versions of NTSC/PAL/SECAM and MESECAM.
There is no reason why Stereo's will not work. You just need an adaptor for that as well.
I am in the same boat. I will not be taking too many electronic items except for a LCD TV (which has NTSC/PAL/SECAM) and power supply between 110V - 240V. I will also be taking my Bose Home theater system and just get an adaptor for that.
