Fry me a river

Electronics emergency! I have to install a panel tomorrow that I wired up with the AN6884 IC
, it was working fine, but then I stupidly and hastily used an AC adapter without testing the polarity....
Here's the panel when it was working properly

. The IC was immediately fried when I hooked it up, I quickly replaced it with a different AN6884 chip and it more or less functioned, but now one LED remains dimly lit in the third row no matter whether or not there's sound triggering it. I can't imagine why that one LED remains lit, I replaced the particular LED with a new one and the problem persisted. I suppose there's a current leakage of some sort? Could that be attributed to a capacitor in the circuit or something else? Could the new IC be wonky? Any idea what I need to replace?
I will try to give more info as necessary. Thanks.
