Default Installing new laser on Sony cdp-x3000es

Hi guys, found this forum when looking up on how to change the laser on my cd player.
I recently acquired it as it fits well with my other equipment but noticed that it skips quite badly. From sometimes jumping back a second on early tracks to looping 10-15 seconds on later tracks. I've ordered a replacement laser assembly but feel a bit insecure about how to proceed with it as I've never switched an assembly before. I've read both that it's a drop-in replacement with no need for calibration and that calibration is needed.
Anyone have any tips for me before I disassemble the unit? I do have the service manual.

EDIT: I'm also wondering if it's the right assumption that it's the laser thats failing? When a track loops and it's the disk that moves over the laser, could it rahter be a faulty motor instead?

Make sure the protective solder blob in the ribbon cable is removed before switching on. There are appliances where You have to store calibration data on the eeprom. Usually numbers on a sticker on the laser itself. Check the service manual.

You can find the service manual @ Elektrotanya | This site helps you to save the Earth from electronic waste!
After search wait until "get manual" appears, easy to miss.
As you seem to be a newbie, the usual tipps:
Expect the laser to be the last part to fail, though
it is very likely that the laser did gather some
dust underneath the lens as the x3000 is a top loader.
The guy from Lampizator had some cleaning tipp
for older laser assemblies, they might give a hint.
Check solder joints, lubrication, power supply, contacts
before dealing with the laser.
The spare kss-213 might be inferior to the
original kss - so handle with care (ESD) the solder
blob mentioned, while swapping
you might find you' ll still need the original.
