Hi,

Recently I've bought a Sony SDC-500 Bitcorder, which turned out to be in need of new belts. After replacing them the recorder seemed to function fine, but then a problem popped up. Pushing the play button moves the pin of the eject lever out of its position and after pushing the button a few times the pin drops out, as well as the eject lever and its spring. This is caused by another lever at the bottom of the PCB, which moves the eject lever to the right when the play button is pushed. The spring of the eject lever is compressed when this happens and as it rubs agains the pin this is moved a bit. On page 12 of the SDC-500 service manual the eject lever is marked 27, its spring 28 and its pin 18.
I guess that I made a mistake when reassembling the recorder, but I can't figure out what is wrong. Can anyone help me?

Best regards,
Bart

Why not post some pictures of the situation?

Is this clear enough or should I also post some pictures of the actual hardware? The marked lever without any numbering is moving towards the base plate when the play button is pressed.

These are images of my recorder. The metal piece that is closest to the capacitor moves the eject lever.

I would be helpful if anyone would be so kind to open their Bitcorder and take some pictures, so I can make a comparision. As you can see the eject lever in my recorder is mounted a bit crooked, which could be part of the problem.

Sorry BartH, I don't see any images ....
I have the SDC-500 and I can open it and take some pictures. Can you upload your images again so I can see what you need to see?

Hi Skyblasc, thanks for replying.
I can see the images on this page, also in another browser. Could it be caused by the cache of your browser? If not, I can try to upload the images, but as far as I can see I can only add links to them.

With the help of Skyblasc, who sent me lots of pictures and even a video, I was able to fix the problem. My Bitcorder turned out to be assembled correctly, so I decided to degrease the pin and push it firmly into its position. After that the pin stayed put. So many kudos to Skyblasc, for being so kind and helpful!

Maybe you could share the pictures for others as a reference for others. e.g. https://www.msx.pics/
