Subject: botched trace repair?

well i tried to replace IC 31 and a couple questionably corroded traces
by jumping wires point to point. This was to to solve my polysixes
problem of multiple patch keys LED's on all the time (such as D or #6
or the "write ' key )...well, instead of only 2 being on all the time ,
I now have 4 . Could i have overheated the IC 31?, the continuities all
seem fine, the problem is some dont switch OFF.. could this be
controlled by IC 31? I did possibly heat it too much? there are no 'bad
traces'. left.
