4 Line Parallax LCD Proble
I apologize if this is the wrong forum to post this but I have a 4 line LCD serial display from Parallax and it
does not want to display anything anymore. The backlight doesn't even work. Is there a way to test this besides
send serial commands to it from a BS2p. It was a rather large investment so I hope the LCD is not broken.
Thanks
Jim

No software is necessary for that.
The display you getting is a good indicator that the LCD is probably OK.
In two line display I get similar "block" characters, however, you need to check what 4 line display·should be after the reset.

Because when you have both switch are OFF· when you power the display you should see PARALLAX and short after that you should pack man eat all the letters and after that you should see the same thing again over and over
If you do not see this call Tech support at Parallax and see what they can do for you
