Xbox series X 1tb. it turns on however and the controller synced to it, but it won't show on screen using HDMI, Tried numerous cables and monitors but to no avail hence the low price as I do not personally have the time to fix this. previous testing stated it needed a new hard drive also. ideal for anyone who knows how to fix consoles to either keep or refurb and sell. I just dont have the time to do it.
