Pioneer PD-F1007 CD player not reading

[Xabi]

Hi guys, I need some help with a CD player. It is a pioneer PD-F1007


The issue is that it doesn't play any disks. The disk gets loaded, spins up, but it doesn't actually plays. Just keeps spinning until I stop it.

If I put in the CD the wrong way, it will eject it quite quickly, so the unit at least understands that a CD is in and if it's in the correct orientation, tries to read it, but for some reason it can't.

I started with cleaning the lens to be sure, but ofc that didn't help. Also the laser is ligthing up at least, so it's not totally dead. The only real thing I did so far is I replaced the memory cap and fixed a few joints which was corroded by the old, leaky cap. But that's a different issue.
The pickup unit iitself is clean and everything moves smoothly.

There are a bunch of pots on the board: one on the back of the laser, and a few on the boards labeled as:
focus gain
focus offset
focus best
tracking balance
tracking gain
RF level

I didn't touch any of these so far. The service manual talks about the adjustments but I was too afraid to do a deep dive yet, so I tried to find something online, but there is so much that could go wrong I thought asking for advice from someone who is experienced with these stuff is a safer bet. There might be something pioneer-specific issue or some issue that could be easily identified by someone smarter than me. At least I hope so.

Any idea, what could be the cause with these symptoms and if it's fixable?

It might be the lens that requires replacement. Rest looks fine as per your description.

Hello
don't waste your time, don't touch any potentiometer, 99.9% pickup assy problem, PEA1335 in your case
the only thing you can try is the very small SMD trimmer (Beam_PW) on the pickup itself, try to turn it 2 degree clock wise, sometimes it work, otherwise just replace the pickup assy
