Lights on BlueRov2 not coming on

[EliotBR (Eliot)]

Hi @Corrinne99, welcome to the forum

@Corrinne99

the lights on our new BlueRov2 are not turning on -(they did come on the first couple of times we powered up the equipment). Can anyone advise why this might be the case?

My main ideas are

1. Incorrect parameters
   • Make sure the output channels are selected correctly in the Lights page
   • Possibly try resetting your parameters from the Tools button in the Parameters page
   • Make sure your joystick button functions are set up to control the lights, in the Joystick page
2. A cable is disconnected/cut
   • Check the power and signal wires within the enclosure, and the cables to the lights
3. Something electronic is fried
   • You can check if the lights are working by connecting the power and ground wires as normal, and then connecting the signal wire directly to a 5V line, or to the power wire for the light
     • This turns on full brightness - be careful not to look directly at the lights when doing so!
     • If the lights do not turn on they may be damaged - please check for cracks in the lenses, see if there looks to be water in any of the lights, and contact support@bluerobotics.com to let them know the context and sort things out from there
   • If the lights are working fine then there’s either a parameter issue or the output pin of your autopilot board is fried (which should be testable by connecting the lights signal to a different output channel, and configuring it as the new lights channel)
