At present I have been using the Nvidia Jetson TX2 develop kit for learning. Everything goes well these month, but today suddenly have some problems when I press on the power button. So normally after pressing the power button, CR1 should turn green, and there would be also connection instruction when I using the sdkmanager on the host computer. However now the CR6 turns red for a while instead, and then the platform could not be powered on, and there is also no instruction for connection on the host pc. For one of the reason maybe there exist some failure in the hardware of the platform. So what is the procedure to apply for a RMA or how could I get a support or communication with the customer service by NVIDIA. Really looking forward for the advice. Thank you!
