Hello. I got in a torn apart xbox one S. It was sold to me dirt cheap since it was sent to a “repair shop” that screwed them over. All they needed was a hard drive swap since it turned on for 15 seconds then off, but this “repair shop” unmounted the whole motherboard, screwed up the X clamp, the whole fan assembly was dancing on top of the processor. PLUS, they even had the nerve to remove the HDMI Retimer and not put it back in, I’m guessing they kept it for themselves, and the front power button board. Anyway… To the issue…
I got it up and running, installing a new hdd, new retimer, and new power button board. Got the software installed and it boots. But the disc drive does not work. I have replaced the whole drive with a known working one, just to see if it would insert the disc, but no. After checking voltages, I only get 3.3v on one of the lines going to the drive, there is no 5v, no 12v, and it’s alsmo missing a second 3.3v if I’m not mistaken. And no shorts to ground on any of these lines. Another issue it has, (just mentioning in case it has a connection), it doesnt seem to detect an ethernet connection correctly, while in the initial setup, it said connected, but the while looking for an update it always would fail, I had to use wireless to get it set up. The ethernet chip does not seem to have been removed.
Does anyone know what voltages are always present on the drive? I dont know if the 12v mosfet switches on until it detects a disc inserted or if it is always on. I do not have a working xbox board to figure it out.
Thanks in advance.
