YES, i scraped out the old traces (about 5), even under the IC31, then replaced the Ic31.... But now that more of the LED s stay on, im more confidant that the IC31 controls selecting the patches, but no one seems to confirm this . I wonder if i need to get another IC31...do it again with less heat applied to the IC when soldering....any other suggestions?

Did you totally remove the "bad" traces, or did you just jump them
with wire? The "bad" traces could still be shorting each other...
