Amiga A2000 black screen, scheme needed

Hi, im try to back to life A2000 rev 6, i was find two broken traces near CPU (battery leaked), this traces was reapired (via microscope) but Amiga still give me only black screen (video signal is present but nothing more) What i guess more traces can be faulty but i cant find scheme for this board. On Amiga PCB Explorer is only A500 but connections betwin ROM and CPU are different, in other schematics what i find its the same situation. Maybe someone have correct schematics for rev 6?
