Stereo CD reader issue (Kenwood KDC-252u)

The stereo is a Kenwood KDC-252u. When I put disc in, the stereo goes into a loop of reading disc then all the lights on it turn off and it starts again. I have tested this with other CDs an got the same result. I got TOC error twice while tinkering with it, so I cleaned the lens but the result was the same loop. The radio, aux, and usb all work on the stereo.

I'm not sure if this is purely a failure with the laser reader mechanism or it there is different fault with the stereo. I might upload a video later of the issue since the file is too large to be attached.

Edit, just uploaded the video:

 

I've tried with both pc burned and store bought discs, and had the same result.

 

I just tested it with the top off so I could see if the disc rotating properly. The disc wasn't rotating, it only twitched when the motor tried to turn it.

 

I cleaned up the disc tray and laser pickup with some alcohol but it is still not play the discs. I also tested the motor separately to make sure it work, which it does. Only difference now is the stereo displays a TOC error rather than going into the reading loop.

 

I did some work on the stereo today and found there was a misalignment issue caused by the disc hold-down piece. I fixed the alignment and I still have a TOC error, but at least now the disc spins properly. thanks for the advice about misalignment.
