I have a PS3 that suffered from the YLOD, I fixed it so that the unit would load, but now I get a blue light where it thinks the drive has a disk loaded but it doesn't. Could this be related to the YLOD issue that was fixed or is the drive itself out? I have some articles about steps to take to reset the drive, none have worked. Also heard mention about a disk in sensor but this drive doesn't seem to have one? Any advice would be great.
