Trying to get a camera going on my pv2+. I got this thing used. Installed a new ribbon cable and found out the main board up top was bad. Just got another board and now the LEDs blink red and there is a binding noise. I took it back apart and hooked up just the main gimbal board and motor. When you power the bird on the top motor will just spin wide open. While it is spinning if I connect the ribbon cable back up for the rest of the camera the top motor stops spinning and acts like it's in a bind. Any ideas what the issue might be?
