Phantom 3 Repair Services offered for the Standard, 4K, Advanced, and Professional models include camera repair or replacement. The critical factor in repairing a Phantom 3 camera is the condition of the main circuit board, which is not available for individual sale. It can only be obtained from a new camera. A defective camera board is indicated when the gimbal balances correctly, but the DJI GO App displays "No Image Transmission," and the app screen is black, with no video input.
