There are a few other potential causes, for example:
– the LCD might be damaged, although this is very unlikely unless if you have reason to believe that it’s damaged by 24VAC
– the MCU’s reset line (pin 1) is for some reason held to ground, causing the MCU to remain in reset state (also very unlikely since you can program the MCU successfully).
