Hello rocky1979!
Thank you for crating a post and for attempting to troubleshoot on your own.
We can see here that you are having an issue with your Quest 3 not turning on after you experienced some fan issues.
We are going to walk you through a couple troubleshooting steps that might help get you back into the Metaverse.
Firstly, please make sure all third-party accessories are removed from your device and your headset has sufficient battery charge by leaving it to charge for 2 hours, please take a note what color the charging LED is after 2 hours, as this can help determine what issue you are facing.
After you have charged your headset for 2 hours and the LED is green, you should be able to turn it on. If you are still seeing a black screen after you have powered on your headset, we would ask that you try hard rebooting your headset,
- Pressing the power and volume down button simultaneously for 30 seconds until you hear the boot-up sound.
- Use the volume buttons to highlight "Boot Device" and press the power button.
- Using the volume buttons highlight "Yes" and press power button.
After you have charged your headset and the battery is red or you have tried the above steps and it is still not working, would we ask that you contacts us privately be clicking on your profile and selecting message, making sure you are logged into your account.
We hope to hear from you soon and wish you a wonderful day!
