If I understand correctly, whenever an LED lights anywhere, the LED in row 1 but in the same column as that LED lights up as well. That suggests that the transistor on row 1 is stuck in the “on” position. Using your multimeter, check to see if the base pin of Q1 (the left-most pin, connected to RB1) is stuck in the low-voltage position. If so, it’s likely that the transistor is OK, but is receiving a bad signal. Check to see if that pin is electrically connected to nearby things. Then, check the other end of RB1 to see if it might be shorted to pins 2 or 20 of U2. It *should* be connected to pin 3 of U2, and that pin alone.
