Hi all,
i have a problem with my Marantz CD-12 player,it can't read any discs anymore.It has a CDM-1 mechanism,and it seems to me that the laser power supply is a bit low.There is a small pcb under the subchassis with 3 potmeters,but i'm not sure if 1 of them can be adjusted for the power supply.
Does anybody have any sugestions?
