Red lights

[Ghost]

My phantom 2 vision plus has all red lights on start up and won't start motors but if I tilt the phantom the lights turn green and flies normal. How do I fix this.

You can start with the manual on what the lights mean:

You can also attach the Phantom to the Assistant for more information.
