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?

I'm sorry the question says CFD-8, but the site doesn't have the 510 in its database.

I've been trying to fix an old CFD-510 Sony Boombox I found a while ago, everything else works pretty great, but the cassette deck needs a new belt. This is easier said than done, as the idiot who had it before me sealed the access points with a resin. After a LOT of rubbing alcohol later, I can peel back the access point, but there are things in the way, and I can't figure out how to put the belt in. Would anyone here have any idea on how to help?

I tried swabbing the player head, and it got rid of the buzz for a short while and then it would come back again.

The model is WM-FX193.

What might be the problem here?

FF works, RW works. When I press play I can hear the recording, but the tape spills out after it runs through the capstan and pinch roller. The take-up spool/reel/spindle does not move.

I’ve checked the tire wheel which is supposed to drive the take-up spool with friction and it slips. So I cleaned the tire wheel rubber and dried it, which seemed to improve it as I turned the capstan manually. But as soon as I add power the take-up spool hardly moves and the tape spews out.

I cant see how to improve it - it can’t be the drive belt as it’s new. The spring which pushes the tire wheel against the take-up spool works well - Is there a drive that I cannot see under the take-up spool? Or should I replace the rubber on the tire roller? If so, where do I get that from?! Any help appreciated.

I added a video showing what the display is showing from the FX453...

And yes, I had it fully put back together with all the ribbon cables connected and still same issue.

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)

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
