Hi members! I am currently trying to revive a DD-22 walkman. I already checked power positive on PCB with a MM. I am new to electronics and do not know how to read circuit layouts well. Who among you has had a similar problem plus a solution to it? Thanks in advance for your help.
Update: Motor is operational. With PCB unmounted, leaf and cassette detect switches bridged REW and FF work continously - with and w/o rubber band as a temporary belt, with and w/o cassette in compartment. Play runs for max. 2-3 seconds before stopping. When PCB is in place in 1 out of 10 times any of b.m. actions work. Any ideas?
Next success: cleaned the motor cone and flipped the capstan ring. Now tape plays - but now I got a small problem. I bridged the leaf switch plus the tape loaded switch and I absolutely cannot grasp how it is activated.
Here is my personal problem: I absolutely cannot grasp how the leaf switch should be activated - any suggestions?
Looks like the lever near is what pushes the lead swich, but it must sit lower for that to happen. The end marked X should go into the recess below.
Valentin, thank you for your reply. The distance is too far for the lever to activate the switch. I unbridged the switch and the motor does not start. It seems there should be some kind of element that should close the gap between these 2 parts - but I cannot see any part shown in the exploded view that could play the part. Also, when pressing the FF, REW and PLAY buttons, the lever only moves very little toward the switch.
Problem solved - the lever activating the leaf switch was not flush with chassis. Now the lever is under the motormount and can travel the space to the switch. Also the motor gets pushed away from the capstan rubber to avoid creating dents in it.
