I've now repairs quite a few HS-PX310 and variants. One thing which has got the better of me on three of these machines is non working play and stop buttons. I have checked and double checked the buttons themselves, the solenoid and pretty much all the components and tracks - everything works! I believe there is a common fault to all of these but I can't work it out - has anyone?
Sorry if I answer only now .. I haven't seen the schematic of this walkman but maybe this can help you aiwa hs-pl50 without audio ..... restored | Stereo2Go forums ok i saw you solved
