Casio CZ-101 synthesizer OLED display retrofit/repair/replacement

The Casio CZ-101 synthesizer (as well as the CZ-1000, CZ-3000 and CZ-5000) has a display that can be dim or missing pixels nowadays. Also the original display is hard to read in the dark because it lacks a backlight. The Casio CZ-1000, CZ-3000 and CZ-5000 have the exact same display as the CZ-101, so this video should work for those synths as well.

If you want to replace it with a LED backlight LCD, you run into 2 problems: most LCD's are on smaller boards, and the frame is thicker because there is a backlight under the screen.

Today I replace the LCD in a Casio CZ-101 with a nice new OLED display that exactly matches the original dimensions, works straight out of the package, and has a nice unlimited viewing angle and stellar contrast. You can get these screens in various colours, but I chose yellow because I think it matches the yellow waveform and CZ-101 logo print on the case.

Used Display:
Electronic Assembly W162-XLG in greenish yellow 84x44mm.
