i have an Igt smld that has been driving me nuts. It has a 14 dynamic button panel that had a bad board. I changed the board to a known working one that I tested in a g20. I still get the CSDA flashing on the buttons. I swapped the hdmi and usb to brand new parts and still no go. I changed the flex also and same issue. The only thing I can think of is the bfdb file is for only 10 button? It is bfdb0004. The chip is bfd00003. Anyone have any ideas? Also I have the dips set to 1 and 2 on for the 14 button and have CSDA. if I set it for a 10 button with only dip 2 on, the middle 10 buttons seem to boot correctly with the Igt logos but after the machine boots the machine says invalid button id.
