Sl-XP5 not reading the cd

Gwent

I have an SL-XP5 and right now it does not read the cd, only rotate the cd. I still can see the red light beam come from optical pickup lens. I tried to measure the variable resitance on optical pickup part and  change it from 5.6k a little bit one by one (5.6 -> 5.3 -->5k....to 1.5k)and check slowly each change, my xp5 from didnt rotate the disc ---> can rotate the disc but still cannot read cd cd.  Can anyone help me to know the part number of the optical pickup lens please? I think i will buy new optical pickup lens and try to replace it to see if it can run. Thanks

Xp5's common issue is the lens fails to focus up/down due to focus coil stuck. Pls remove the oxidize trash generated by the magnet and paint the magnet again instead of replacing the laser.
