E-mu Emulator Sampler User Forum for the EIII EII EI and EIII XP

Has anyone replaced their LCD display? It looks like EMU used a generic LCD Board.

I'm in the process of installing one but do not have the PIN configuration on what the PCM board is expecting. It looks like the pins are:

1 Vss Display power ground Molex ground
2 Vdd Display power +5V Molex +5v
3 Vo Contrast Adjust. Altered by adjusting the voltage to this pin, grounding it sets it to maximum contrast. * Molex ground 
4 RS Register select Parallel pin 16
5 R/W Data read/write selector. Its
6 E Enable strobe Parallel pin 1
7 DB0 Data Bus 0 Parallel pin 2
8 DB1 Data Bus 1 Parallel pin 3
9 DB2 Data Bus 2 Parallel pin 4
10 DB3 Data Bus 3 Parallel pin 5
11 DB4 Data Bus 4 Parallel pin 6
12 DB5 Data Bus 5 Parallel pin 7
13 DB6 Data Bus 6 Parallel pin 8
14 DB7 Data Bus 7 Parallel pin 9
15 A LED backlight power +5v Molex +5v 
16 K LED backlight power ground Molex ground

If you want to replace it because of an extinguished back light only, then you need not to replace the whole LCD, but only the EL foil. This is relatively easy task (I have done by myself).

If your LCD failed, see what Emulator Archive says:

"LCD Overview The Emulator IIIx uses a 20x4 character LCD. We have not identified the exact LCD model (an Orion?), but a possible replacement (untested yet) is an Optrex DMC20434.

LCD Age After around 2000 hours use the LCD will need replacement, and its a good idea to replace the LCD whilst parts are still available.

LCD Inverter The LCD backlight (the blue colour) is driven by a small inverter that generates 100VAC at 400Hz from a 5V supply. The inverter is a NEC (NEL-D32-46), and its a small black plastic box that sits on the main digital board. The inverter can fail, which means no blue backlight, in which case it needs replacing. "
