cmos sensor camera nikon D4

dears,

i have a problem in my camera Nikon D4 especially in the cmos it was damaged while clearing the camera ,

i bought it two years ago from the Grand Store in Dubai ,

i live in Lebanon Now , and here in Lebanon i tried to contact the Nikon company or ther certified outlets here they did not accept to repair it , so i would like to know if it could be repaired and how much it costs if i take it to the USA

please i would like to have a feedback as soon as possible ,

it is an urgent problem

best regards,
