pls check if the size is available at katunayaka duty free for duty free price. if that size is available for duty free prices u can ship it here. i think the largest one katunayaka had was 42. not sure about the present situation. if that is the case u have to pay duty for the oversize TV. if u had to pay duty that is not economical machang.
and u have to come with ur passport, to paliyagda warehouses to clear it, if u send it to someone elses name, then the tax will be higher. there are tax reductions for ppl who worked overseas and shipping their household items.
but if u know anyone who works in those warehouses (custom) it might be easier
