I recently purchased a Display-O-Tron and have run into an error. While the blacklight works text does not appear. According to the installation guide a message should have appeared upon installation and it did not. I have tried the lcd.write function and nothing appears.
I am using a Pi 3 B with Raspian. I have tried a fresh install of the OS and updating the OS. Neither have fixed the issue. Nor has a myriad of other little tinkering. Any help resolving this issue would be great.
