I’m fixing an old dji phantom 2 vision+ and I’m having trouble with the gimbal

Hi guys, whenever I turn on the phantom the camera shakes horribly, It has never been in a crash so It’s not the mount that’s broken. I’ve been trying countless tutorials and guides on troubleshooting to no avail. Do any of you guys have an idea of what it might be? I’m sorry if this is not the appropriate subreddit but over /dji nobody answered me. via /r/drones https://ift.tt/2D2cZyM
