The picture says it, I tried resetting, af lock, replacing the cam. Also a blue chip pops out when I remove the cam what should I do. There is no mic speaker on the front and compass and jog pacer apps wont work
A bit too many problems at once usually lead to liquid damage as primary cause. If you already replaced the camera what’s left is most probably a board issue that needs microsoldering skills and tools, there’s only so much one can speculate being the problem without thorough testing. Unless you have the skills and time to invest, a reputable tech would be needed to troubleshoot/repair it.
