Series X Black Screen - Out of Options?

Hello,

After powering on my Series X there’s simply an immediate black screen, no boot up logos or anything. I can still connect a controller, where it seems like it’ll still respond to the usual three options (power off console, power off controller, reset console) when holding the middle Xbox button on said controller. Discs can still be inserted and ejected. All options that I’ve tried are as follows:

-Switch HDMI cable, HDMI port on TV

-Fully power cycle the console via holding the power button for 10 seconds, disconnecting power cable for a few minutes, powering back on

-Booting in low resolution mode via holding power and eject buttons for ~15 seconds (makes two beeps as expected, no image on screen)

-Booting into troubleshooting menu via holding eject and sync, then tapping the power button (makes two beeps then ~5 seconds after the second beep the console powers off)

-Factory reset via plugging in USB with required files, then holding eject and sync, then tapping power (makes two beeps, but immediately powers down after the second one)

-Offline system update via same steps as factory reset (with system update files instead of factory reset files of course) since as mentioned I can’t access the troubleshooting menu on startup to perform this the normal way (makes two beeps, then a third beep immediately after the second, console stays on but with no result)

In all applicable troubleshooting instances where the console remains on I’ve let it idle for 10+ minutes per Microsoft’s recommendation in the off chance it’s being slow to perform its usual boot up checks, unfortunately still nothing. Any other possible suggestions, or at this point would my best bet be to send it for repair/buy a new one?

:)
