Sony WM-EX612 PCB

The WM-EX612 PCB is very easy to remove as they have used a socket for the audio head ribbon cable. In other versions, they had soldered it directly to the PCB and it was more difficult to remove it.

It is also necessary to remove the solder from the tape sensor switches. These switches are often the reason for the player not starting. One way to test it is by soldering a loop of wire across their terminal pads.
