CDJ 1000 MK3 CD reading loud humming

Hi everyone

I am having an issue with the cd slot starting to hum as soon as I put ANY CD in.

Tilting the Player like 20-30° in the front or back helped for a while but it's getting worse.

It sounds like something might be loose that stars vibrating as soon as the cd starts spinning. Is there a possibility that its just a screw thats not tight enough or something like that and do you have any footage on how to properly dismantle/reinforce the parts?

Thanks for your help on this..
