Another vote for the cartridge here. I've had numerous issues with various MMC cartridges over the years, suspension failure is pretty common.

Where do you live? If in the UK, I'll lend you a decent cartridge to try instead.

Very generous Peter and to the OP, this should be the first thing you try before doing anything else that could compromise the TT further.  Once the cartridge is ruled in or out, the rest can follow.  If Peter's cart works, it's yours that's the problem and you can return it to the seller.  If the problem persists, there is a fault in the TT and further investigation is necessary.

Thank you.

Sorry for the triple post, I do not why it happened.

Also I can't send PMs for some reason, so, Peter:

I really really appreciate what you are offering, it would really help me out. I live in Czech rep. which is in EU thankfully. You do not have to worry, we are not Soviet country anymore and our post is quite good actually:)

I will of course pay for all post expenses and I am more then willing to send you some deposit via paypal or bank transfer.

Thanks again.

Nothing so far - email me -  your address - I'll dig something out! I will want it back sometime!🙂

Hello everybody,

I would like to close this topic and say that you were all, of course, right:)

The problem was cartridge which was clear right after I installed new cartridge and hit play.

Thank you all for answers and mainly Peter, who sent me (without any deposit or anything else) cartridge to test it. And not just any cartridge, he sent the top of the line MMC20CL.

Rally amazing this B&O community is:)

Thank you and have a good day. I'll surely have - listening to my -now finally fully functional- 4002:)

Very pleased to hear it is working. I would suggest the best way forward is to use the 20CL I have sent but consider getting Axel to repair the cartridge you have - you can get it made into effectively whatever you want - I favour the Shibata tipped version which, dare I say it, is even better than the CL. Once you have a new cartridge to your liking, you can send the CL back but no rush!
