I have an IPAC4, but only a two player panel (don't ask). Everything seemed to be working fine, but some time ago the shift function seems to have stopped working. I really only use one shifted function, and that function is for ESC (player 1 start and player 2 start). I brought the IPAC4 up in Notepad and hit Ctrl-Alt-P like it said to do. For some reason the board thinks player 1 button 8 and player 2 button 8 are pressed and/or shorted. Funny thing is I don't have anything connected to either of those inputs. I have unconnected the surrounding connections around those two inputs, but it still reports those two inputs as being pressed/shorted.
Edit: I forgot to mention that I seem to be able to hit 'r' in notepad to reset the IPAC4, but then it says to hit the next button or 'e' to exit and when I hit the e to exit it doesn't exit (unless exit doesn't do what I think it should do).
Advice?
Thanks!
P.S. What are all of those "blinks" on the LEDs on the IPAC4 when it first powers on? Is that a clue?
