Tracks Found Cut In Philips AZ1047/94 CD Sound Machine
This set belongs to my school classmate and was brought with the complaint that it was dead. After opening the covers, I dismantled the set completely and did a thorough cleaning up.
While doing retouch of the dry solders, I saw that the power supply pins were detached from the PCB and the track was also cut underneath. So, wired it up and soldered it properly.
I also scrutinized the other PCBs and replaced all the electrolytic capacitors as the ESRs were found to be out. Completed the patch up of dry solders on the other PCBs as well.
I lubricated the connectors and also the rails of the sliding motor. After this, when I checked up, the set was working perfectly well.
Mission accomplished and satisfaction got collected!
