I have had my kit up and running to the temp sensor project. Everything worked fine. It took a fall from my bench. Now I have a blank LCD display. Anyway to trouble shoot it to be sure or should I just order a new one?

Just to be sure, I'd start from scratch with the guide and re-do the assembly starting with just the micro-controller on the board. If the display doesn't look cracked, and the board shows no sign of damage, it most likley survived the fall.

Hi ACWarrior,

I agree with Rick. If there isn't anything that physically appears out of place with the LCD, then it most likely survived. The problem you are seeing is most likely a loose wire. It is conceivable that the jolt might have caused the program on your MCU to become corrupted. After checking all the wires, I would try uploading the initialload program again, make sure the MCU is still up and running with a fresh program.
