What was the original issue, did you replace the entire deck as one piece? Can you see the red light in the lens when holding the lid sensors down, is the lens bobbing up and down, did you try cleaning it with isopropyl alcohol, did you try reseating the ribbon cable, did you remove the anti-static point, does a CD read, are you using the correct replacement (mainly the spindle is going to be the issue [take note that the worm drive cable isn't backwards on the connector as well, this differs between models], try swapping the pickup into your original assembly).
