I spoke to Andy from TNL yesterday regarding Xbox360 warranty and he told me that all XBox360 sold here in KL don't have any official warranty from MS or from the shops. He said that they can't repair it if any thing happens to it as the xbox360 is consider new and they don't have any access to get any spare parts for it.

He told me that, if I want to get it repair, I have to RMA it to Singapore with my own expenses. I'm not sure what's the official warranty period given by MS if you buy it from them but I've read somewhere in other forums, in US, MS gives 3mths warranty only for every xbox360 but you can pay extra to get an extended 1 yr warranty.
