I got a jhd 20x4 digital display last week and tried to setup with my Raspberry pi. After performing the setup the Backlight dispay comes up but when I send some message that is not getting reflected.
- Is it because the display has gone bad.
I had followed the wiring suggested by Matt

I have also asked Matt on the same. Any help in tweaking this will save my day.
