decided to replace most of displays in my studio equipment that are dead or allmost at end of life ..
most synths is now hard to edit due ageing of backlight on displays so....
So I started with EMU - SP12
ordered display from Ebay for cca 5$ ...that displays need some work to be instaled in SP12 so here is picture how was that with old display and how it looks with New one!
Needed some small main PCB modification on SP12 control board, used 5v for led backlight from LEDs on SP12!!!
only problem is wiring!!!
on SP12 pcb its 1-14
and on Display is 14-1 so wires need too be crosed .. (or flat cable if you use it!!!)
-on pin 3 is LCD contrast and i used 10K multitrim turn pot that works just fine to adjust display !!!
Before
AFTER
Removed hi voltage from system.. made by inverter for backlight in original Display, also no more HI frequency sound from inverter!!!
Looks clean and will live a long life
display really looks like this on picture and its fun to work normal again on SP12 now !!
5$ is bargin since guys on web ask for backlight cca 25$ ..
this will fit (with some small work) SP12, SP1200, EII!!! I checked that!!! and wont fit into EMAX!!!!!!
