I've created and written the FW to the PCB 2 times and both result in the same noise. It sounds like the laser is not moving properly on the rails. It makes terrible clicking noises when trying to read a disc and will display mixed media half the time. If I put the original PCB back into the drive, the drive operates normally with no noise issues and no read issues with retail discs. I'm not sure where the issue lies as the original PCB works fine. Thanks in advance.
