I am now stuck on a sound quality issue along with the volume meter problem. I only listened to it for half a song before the belt snapped initially, so I don't know if it's my tinkering or a consequence of the Potentiometer. I've cleaned the head, pinch wheel and capstan system, but not demagnetized yet, though I doubt this is the issue.

The potentiometer is spinning round and round instead of the set limit it's supposed to have, and clicks on or off jumping to random volumes and channels. What is it's part number? does any one have the Manual for the WM-4? Would it be worth finding and using contact cleaner on it?

I would love any advice you have. Regards

Recently acquired a silver Sony Walkman WM-4. Installed new batteries, new belts and lubed gears. When pushing play sometimes it it will start and sometimes not. With the back off I can rotate the silver metal gear by hand and it will eventually begin to work. When it does come on the sound through the headphones sounds like your underwater. I can't seem to find any information showing where to adjust the speed on this model.

Thanks for any help or advice

currently my cassette player plays cassettes, but the eject function no longer works. A spring popped off, and I'm not sure where it goes. The door for the player no longer opens when the eject button is pressed.

Since the eject button no longer works, I cannot put a cassette in without having to press down a plastic piece that is stuck in the down position.

Any help would be greatly appreciated, its mostly a mechanical problem.

Thanks!

The cassette door is stiff to fully open when a cassette is present, but fine when empty. Extensions on the plastic window, latch onto the metal parts of the cassette tray. So much force needs to be applied that I think the plastic parts of the window will wear out even more and fail. The workaround is to use a thumbnail to get some added force on the cassette. Fiddly and not customer pleasing. Otherwise rock the door backwards and forwards about eight times to tease the cassette out.

This problem occurs with all my cassettes. I have tried filing 0,5mm off the top of one (scrap) cassette (adjacent to the recording protection breakouts), so the sprung clips do not hold the cassette so firmly (customer isn't jogging with it!) but no improvement.

Other info: I replaced the counter belt and adjusted the door catch tension, both successfully.

Any solution to this niggling problem or are all old Walkman like this?

1. charging error. it sometimes charged sometimes not charged just like the cable had problem. never had this problem for years since 2009
2. the date became --/--/--. never happened once although years not use.
3. after fully charged, it's working. all the music files available & can be played. JUST the volume up malfunction. volume down is working. now I'm worried, volume has down to 14 after I pressed two three times when confirming the volume button malfunction. HELP.

The below photos show the board which I couldn't immediately identify any issues, with the exception of what may be excess flux????

Any advice would be incredibly helpful, thank you in advance!

I tried the same tape on my deck and it doesn't hiss at all.

What could be the problem? (Also, the belt is new and I tried cleaning the volume button, still hissing)

(Sorry for my grammar, English is not my first lanaguage)
