Something I don't see is the contrast resistor to pin 3 of the LCD. The LCD would show two black bars in the programming mode. The program switch is in the program mode but there is no sign of power.

When this happened to me it was a weak 9 volt battery. Try changing the battery. That seems to be the problem most of the time when people come across this error.
