I can’t start the robot anymore. I push the start button, the robot doesn’t get into the software system, after a while, it turned off. The same problem when I use the remote ON IO. I can do nothing because of the start error, anyone met the same problem? please help me, thanks! ![98132bb6e153febda067b405bf0b3eee2022981546531](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/a/a23110510a3d0f8e2b23e2affb6ad60fe81e523a.gif) ---

That looks like a total misfunctional controller. Request support on [myUR](https://myur.universal-robots.com/#/) by opening a case and describe the problem same way as you have done here ---

This is a typical sign of a faulty motherboard. 🙂 You will need a new motherboard. If it’s a CB2 model, you will not be able to buy the correct sparepart, since UR doesn’t offer support for that series anymore. A CB3.1 motherboard (upgrade kit) will however work in a CB2, as well. You will need to put the correct image on the USB, though. More information can be found in the service manual available on UR’s download site. ---
