Last question before I surrender. I swapped the IC in the dim quadrant (100 quad) and got this weird result: The whole board became non-responsive. Half the LEDs are lit up, but dully (including in a previously dead quadrant!). None of the LEDs now respond to movement. They just sit there.
One point that may be germane. The first time I swapped the IC I put it in backwards and turned the board on. Then I realized I had put it in backward, and switched it. COuld that have messed up the board in that way? Is there some other obvious fix. Thanks, and this will be my last bothersome note.
I appreciate your thoughts!
