CZ-1 Display

CZ-1 Display

2015-02-03 by daveogarf@...

Hi, all

Has anyone out there, who owns any of the CZ Cosmo series had any difficulty with the contrast of the display, e.g. the brightness being good, but the contrast being so faint that the display is all but unreadable? I've fiddled with the contrast control inside, but just can't get anything on the display.

On a side note, has anyone done an LED display conversion for any of the CZ series? I've seen one for the CZ-101, but I think the CZ-1's display is larger.

Thanks much for any and all help!

Dave

fit an oled as they dont require back light but are neon letters they also dont require angle there are several versions with the correct solder connections and if not like on the emaxes you can hard wire it

Have you tried to change the setting of contrast variable resistor VR2  
on the main board MA1M? Maybe it will help...

I have changed display in my CZ3000 for modern one with LED backlight,  
even I couldn't find service manual for this machine. I had only that  
one for CZ5000 and other CZ instruments, fortunately it looks like  
they use the same standard of controller (14 pin HD44780). So I think  
it would be possible to change also display in CZ1, if you find the  
same size.

Details on changing the display for backlit lcd is at 

Http://templarseries.atspace.com/cz.html

For the cz101. So subject to what others have said of possible differences with the cz1 display, the process maybe similar.

most led and oled displays are made by one manufacturer in china

they have stickers on the back for the different manufacturers names but all use the same pcb die

winstar colour fonts raystar and others they use the same pcb

maplins of uk now sell a version that is cheaper that is made by another manufacturer but its the same pcb as i now use that one for the

emax and dss1
