I tried to assemble Adafruit's Arduino LCD 16 x 2 using the instructions RGB LCD Shield: Control a 16x2 Character LCD using 2 pins - Assembly without any success.
After assembly, I uploaded the HelloWorld example sketch on to the Arduino. The shield doesn't seem to be working. The LCD didn't turn on.
If I push back/press the LCD it turn on. Any idea on how to troubleshoot this?
