I have an interesting problem that I can't seem to find an answer to. When I turn my drone on the camera initializes but...

Hey guys, I also have a similar problem. When I turn the drone on, I have a problem with the tilt. It gets to about 100 to 110° and it pulses like it's reinitiating. After that it drop straight down and its as if it's not connected at all, it just flops street down. If I use my hand and lifted up it will start working for a little while. I didn't damage this in any Crash, because I haven't flown it since it was working perfectly. I would appreciate any help as I don't even know where to start troubleshooting on this. Thank you
