Replaced Disc Drive, Drive will not load discs or run
Hello, I replaced the disc drive in my Xbox one X. It would hardly ever read and if it did, it was when I tilted it upwards. I got a replacement disc drive and installed, and it would not run at all or even allow a disc to be installed. I then found the instructions to transfer over the original board into the new disc drive. I have done this, but the drive will still not run at all or allow a disc to be inserted.
The drive is a "used and tested" part from ebay. Is it most likely that the replacement drive is faulty? Or is there something I am missing in this process?
P.S. I am not new to electronics repair or soldering and am confident in the integrity of the work performed.
