Reassembling a Casio CZ 101 after repair

I bought a "for parts" Casio CZ-101 and hoped for an easy fix. It wasn't. Luckily someone reacted to my classifieds ad with a request for a new main PCB. Then I swapped the main board and got sound. But things were not that easy. The screen was missing lots of lines and pixels. And 3 buttons and 6 keys weren't working: it turned out a PCB trace was broken, and that 2 wires in the flat cables were broken. And off course I did a thorough cleaning. But finally I got everyting to work, and I managed to install a nice new perfect fit OLED display in a nice yellow colour matching the print on the case. The result: a near mint working Casio CZ. This awesome sounding synth deserves to be preserved and repaired! Don't bring them to recycling but fix it or share parts to others trying to keep their CZ synts alive! This video is a quick montage, I left out the full transcription I usually make because of the length of the video. If you want to see all the details, watch on a big screen, I recorded 4K to grab all details.
