Things to look for. This is a recent repair that I just did. The MP was in a light crash and the gimbal was jammed up into the carriage. After removing the gimbal and the control board on top, I found that a connector was also lodged to the side.
One of the pins was damaged on the control board. Although the pins are very small, it only takes one pin to cause errors. Also be sure that the GPS connector is secure when placing the top cover back on. Yes, it is a tight squeeze to connect it before lowering the top.
If the the GPS cable is not secured correctly, it can cause other errors besides no gps signal because the gimbal initiation process cannot complete.
