I got the starter kit from the Arduino store, and just got the the LCD "Crystal Ball" project yesterday. I did it, and everything went fine. Then today I went to try to integrate the LCD in my own projects, and it soon started to malfunction.
As you can see in picture one, only the left 16 boxes are operational. The right 8 are always at max, and the middle-right 8 are faded down. I loaded all of the LCD example sketches, and the problem persists in all of them. I checked and rewired the circuit several times to no avail.
I think I messed up the hardware somehow. Could I have damaged the screen somehow with incorrect wiring at some point in one of my projects? I was removing it a lot to get the wires just right, but I wasn't rough with it or anything. In picture 2, it looks as though there are micro-cracks across the pixels on the far right. One incorrect connection that I DID notice was that I had the illumination pin resistor wired to ground instead of power for the duration of the crystal ball project (I was wondering why the screen was so dim!).
Should I ask the store to send me another screen, or did I definitely cause this? If it's my fault, I'll just by a new one. If I got a faulty screen, I may ask for a replacement. Any help would be appreciated.
