Lights and camera, no action

new here, just assembled BlueROV2.
all working well except light and camera.
no lights at all using standard setup. Wiring looks right, what else?

cameral works, but, if using the tilt to extreme it cuts out and ROV has to be rebooted to make it work again.

Any suggestions on troubleshooting appreciated?

You can check that the output signal is being sent appropriately. Go to Widgets->Mavlink Inspector->Vehicle 1->SERVO_OUTPUT_RAW

When you push the buttons for lights, do you see channel 7 change? If so, then it is an issue with the hardware/wiring.

This sounds like the camera cable is getting pulled loose and the camera disconnected from the computer inside the ROV. Can you make sure the cable has enough slack at the extremes?
