I saw Samsung LED 40" TV for about NRS 95,000 + VAT in Samsung authorized dealter in kathmandu. I think you can buy TV in Kathmandu. I understand you can get really good deal here on Blackfriday, however as other's mentioned, the incompatibility in system is not worth it.
I took movie projector this year, and it fit in my carry on luggage. It was really nice projector with 3D feature and cost only about $ 500 in Amazon. I suggest you can think about that.
