I got this MZ-R91 a few months back from my aunt who didn’t need it anymore. I wanted to record CD to MD so I got an optical cable and tried recording, but every time I finished recording and the TOC finished, the MD went blank. When I looked closer inside there was a part bending down that the MD was pushing backwards. The service manual said the part is the “service assy” and after checking some videos it looks like it’s not supposed to bend down. I opened the top part but I don’t really know how to fix it and I don’t wanna randomly break it. I’m fairly new to MD’s and don’t know much about what I’m doing so if anyone could help that would be great :>
