No, the AV eqpt. won't work here.
1. Power 110-240V: Besides the power range of your eqpt. if it's not in this range (in its manuals), u'd require to purchase a 'down convertor', which r specific to the power o/put - so, if one fits a eqpt. - it might not be suitable for another. Thus, u'd end up buying many such convertors.
2. NTSC-PAL System: If u r coming from the Asian region, or regions which work with the PAL codec - u'd not be able to use your US/Canadian DVD's, Blue-Rays, their players & the TVs too - b'coz they work on NTSC codec here. Thus, if u bring-in the TV & the Player from your homeland they could be paired (as existing) but won't play any DVD/BR purchased here. If u just bring the TV or the player - it wouldn't work with any eqpt. purchased here. Besides, the TV will not receive anything (Telecast) here either.
Advise: Avoid getting those eqpt.
