My TX2 does not react when it is powered on by pressing the power button

When pressing the power button,only the red LED is bright. Is it possible that my TX2 module is broken? It’s still working before.

Hi, do you have another dev kit to do cross check? Is there any current change when power on? Furthermore you can check the power sequence as list in OEM DG to see if every timing is correct.

I installed the module on another development board. It still doesn’t work.

That looks like module broken. You can run RMA process as listed in this topic:

Thank you. I’ll try the method in the topic.
