Hi @bill2star,
First, it would really help with some good high resolution pictures, as this helps in diagnostics. Here is a guide on [guide|21499|Adding images to existing questions]
When you replaced the laser pickup, did you first remove the solder blob that is supposed to be removed after transport, but before installing? The laser pickup is supposed to focus in, automatically when spinning up the disc. There should be a much smaller motor that ever so slightly adjusts the height of the laser diode, in order to acquire correct focus.
