looks to me like you still have broken traces on P11 and D03 lines.
S check with continuity meter 2 networks (part designator and pin number):
IC31-3
IC26-14
CN06-6
CN10-1
IC33-9
IC28-13
IC34-13
second one:
IC22-28
CN06-8
CN10-7
also check if IC31 (74LS08) is working properly. This poor little guy
usually suffers the most from battery leakage
hope that helps
