Quest 2 displays for a couple seconds then goes black.

Hey manny12051988, thanks for reaching out! A black screen can mean a few different things, but not to worry, we have some troubleshooting for you to try.
 

First, you will find some steps here to check that the cable is good to go and your PC settings are correct. After this move on to the hard reboot; 

To do this:

- Hold down the power button and volume down button for 30 seconds until you hear the boot-up sound

  If the boot-up sound is not heard:

- Hold the power and volume (-) button down simultaneously until the boot screen loads on your headset.

- Use the volume buttons on your headset to highlight "Boot Device" and press the power button.

- Use the volume buttons on your headset to highlight Yes and press the power button.

Finally, if the hard reboot fails, try our easy-to-use software update tool. 

If you are still having no luck after the troubleshooting, we recommend getting in touch with us over a private message. We will then need to gather some account information to see how we can help you further.
We hope this gets you back up and running, and thanks in advance for your hard work! 

Thanks for reaching out so quickly. I already completed those steps.updated software through pc and did reset same issue.
