Green background on LCD display


Hello guys,

I’ve had this problem on a few boards we’ve produced where the screen rather then black comes up green. I’ve tested the LCD and that’s not the issue and looked at the board and ohmed out the connectors to EMX module and they seem good. Any thoughts would be appriciated. Thanks.


please use a name instead of number 4 so we can identify you easier and so help you better in future.

The only cause for this is some missing connections from EMX to the display.
