Hi. I have the same problem and same situation (my country does not have an Asus support centre). All I can tell you for now is that buying a new camera will not solve the issue. i found one at a good price on AliExpress and had it shipped. Waited for the longest time for it to get here, only to find out that the issue is not with the camera itself, but with the logic card. And having no support centre nearby, fixing the logic card will not be happening anytime soon.
Sorry to be the bearer of bad news.
