Post by: jb on January 09, 2018, 01:00:21 PM

Recently, my Marantz cd player keep have problem reading disc, so decide to replace with new laser len to keep it playing for a few more years. The replacing method is quite easy just need screw driver and careful when disassemble all the parts. Here it goes....

1) Removed the two solder bump from the new CD laser len (this is to prevent static when ship by vendor)

16) finally slide the copper rod back to position and put back the screw and all is done and ready for playing cd again. The process is quite simple and take less than 30 minutes to make the laser len change. The next time if you cd player giving u reading problem, you can try to change it yourself, is not that difficult.
