Doesn't power up after crash

[Kendlcca]

Had my p3 std touch a tree limb, it rolled and came down on its back. Destroyed the camera and gimbal, but I have replacement. Drone will not power up, Have taken cover off to inspect board, no visible damage. battery power 15.7 volts gets to the board. The arm LEDs do not come on with even error codes. Need to decide whether to continue search for problem or replace.
