Good Ole Sony Walkman.

Start with removing the screw on the Underside. The screw on the Backside next. Then the two on the reverse side of the tape controls.

New line.

With a small Phillips head, Pry the sides carefully.

Take care not to jostle the Switches on the top of the unit while removing case. So now we have removed the underside casing from the device.

Find Ribbon Cable that connects to the board. Carefully Pry open either side of connector as shown, then remove ribbon cable from board.

Now we can remove the board from the casing.

Find Door Spring and remove carefully. Then find and pry off (on either side) glued on bumpers- These limit the distance the door hinge can travel in order to be pulled off---

Now gently pry the door hinges on either side off of their pivot point, and remove the front door from the assembly

Remove three screws on backside of cassette door. Then remove panel.

There is your front mounted control board! It is attached to what appears to be a speaker i'm guessing. Possibly for the alarm clock. I found that to be interesting, the little speaker thing. Anyways , thats it.
