Phantom 3

[Flybe]

Switch it on and it just beeps, no lights. Can anyone help. Cheers

Are you new to drones? Have you flown this before? I assume you’re talking about the remote beeping. Any background might be helpful to get replies.

More details needed. Is it charged, etc.?

Had a flight in the morning all good. Second flight turned drone on no flashing lights just a continuous beep.

Same battery, 3 green lights

turned drone on no flashing lights just a continuous beep.

Flight controller issue.

Check voltages on ESC Center Board, look around FC module for cracks in the solder. Connect to PC via front USB and check if any packets arrive. No packets mean FC micro-controller is completely dead, and if there are packets - they will contain some details about what's wrong.

I suspect, since there are no arm lights, that FC will be completely dead. Not powered or just fried.

No-ob solution: just replace the ESC Center Board.

Does the drone need to be on when connected to the pc?

The Phantoms does not have some special low power mode where they work in the background to some extent. They're simply either on or off.

For the connection - this is the same one which Assistant is using in Ph4. Details:

The same thing happened to me when I tried to update the firmware. No lights, continuous beep
