Ok, I got the chip programmed finally. The monitor works fine and the LED turns on when I hit the Phase button. It stays off the rest of the time. But, that's the only thing that happens. I don't get any flashing when I hold buttons down for 3 seconds. I don't notice anything happening to the screen either. I get proper voltages at each pin so I'm not sure what I messed up.
I went the long way with my install. Do you think the way I did it caused problems or maybe an issue with flashing the chip? I tried 3 different chips. I selected the hex file and the elf file from your .zip when I programmed it.
