Character LCDs / NHD-0420D3Z-NSW-BBW-V3 back-light flickers
« on: April 03, 2014, 12:07:42 PM »
NHD-0420D3Z-NSW-BBW-V3, back-light flickers randomly during normal operation.  The display seems to work fine in every other capacity.  I've left the baud rate at the standard 9600.  I wrote a routine to change the back-light to see if I could dim it and that works fine, so I'm pretty sure the dimmer circuit is working properly.  Is this common and has anyone found a fix for it?  Thanks.
