How do you actually get the mainboard for replacement? Is it directly through Samsung?
Nevermind, the parts are available at Samsungparts.com.
I believe the particular part of interest is the AD92-02282A, although I'll write a followup if this is not correct.
I can now confirm the part is the AD92-02282A. Following this guide worked very well and saved me risking $800 on ebay for a used nx500.
i’ve been told that after replacing the mainboard the camera needs to be adjusted which could only be done by a professional workshop.
did you run into any problems with the new mainboard?
