Why is my Xbox one on but displaying nothing?

I do not have an external hard drive and I did try to reset the console yesterday, the issue continued.

I understand the next step that I can recommend here is to do the offline system update method. Please follow the steps from this link, https://support.xbox.com/en-US/help/hardware-ne....

If that doesn't work, it would be best to reach out to any repair center near your area to have it repaired. There seems to be a hardware issue with the console already and the service center doesn't service Xbox One consoles anymore according to the website.

Hi there. My name is Ron, I'm an independent advisor. I will be more than happy to help you.

If there is an external hard drive connected to your console now, turn off your console then disconnect it, turn on your console without the hard drive, and see if it works fine. It can be that the cause of the issue is a corrupted hard drive.

The next step you can do here is to do the factory reset procedure below.

1. Press the Xbox button to open the guide.

2. Select System > Settings > System > Console info.

3. Select Reset console.

4. Reset and keep my games & apps.

Also, if you have issues when factory resetting and are using a wired connection, disconnect the ethernet cable while it resets and then connect it after the reset is finished. It will connect to complete any updates required.

I paste the same answer I made to a post you tacked on to.

There will never be a OSU1 file available to consoles enrolled in any Xbox Insider previews. The console has to be unenrolled from the preview before attempting an Offline System Update (OSU).

Normally, when the console is unenrolled the latest General Availability (GA) OS will be installed via the internet so a OSU is not required if your network connection is stable.

If you have unsuccessfully attempted to use a OSU1 file without unenrolling from Insiders, you need to factory reset the console.

The factory reset will install a base OS and if you have a stable network connection the console will download and install the latest OS available.

Reset console to factory defaults

System Update Solution .. Take note of the Insider section of this link

"Last Alpha Skip Ahead Update was early March 2023"

This is not true. There have been several ASA Insider updates since March 2023. There was one yesterday 20th April 2023. I suggest you visit the Xbox Insiders Reddit site regularly and /or check the Insider app everyday if you want to stay in the ASA Insider preview.
