Many including myself had some concern on US TVs working in India. USA uses NTSC signal and India has PAL. After doing some research in Internet found that Dish TruHD MAY work for US based TVs. I decided to try it. Called Dish and the technician came and installed Dish. Once the output was set to 1080 standard in the STB the video came perfect in my Sony TV. So its confirmed that it will work. I have my TV connected through HDMI cable. I also bought a step down transformer to convert 220v(India standard) to 110v(USA standard) as my TV manual said it will only work at 110v.
TV model: (LCD) Sony Bravia KDL46Z4100
