LCD display replacement (Roland MKS-50)

Post by logix » Sat Oct 10, 2020 5:24 pm

The display backlight of my MKS-50 looks kind of weak and it might be time to change the display entirely. Does anyone have any info on how and which replacement display works?

Some cheap 16x1 LCD with LED backlight such as,

or a 16x1 OLED, but this requires also replacing the MKS-50 firmware to make it compatible.

Thanks.
So a standard HD44780 type 16x1 display?
Are the pinouts identical?
The service manual says the display is a DM011Z-1DL3, but there aren't any pinouts or other details there, nor am I able to find anything online about it.

I remember messing around with a Roland D-110 LCD replacement where the connection was almost the same as with the original one. Fortunately I got a lot of good help here and it worked out in the end.
