CDM12.1 what's hided inside......

Most of 90's CD Players adopt the well known Philips CDM 12.1 .

This is a real work horse but many time it could  turn in a studborn mule that refuse to work........

........there are many reasons 'cause it stops working: it needs to be cleaned with cotton wad and alcol....sometimes it appreciate to be sprayed with compressed air but at the end of his life there is a dead or weak laser diode.....let me introduce Mr 30PAH16.......

.....so you want to dare to change it instead of the whole device?.....well.....good luck!!!! :-)
