Can not remember which one off the top of the head, but a quick search of A600 black screen, will point you in the right direction. Just a suggestion, possibly another area to check.

Which cap is on the reset line??
As @supaduper indicated, the one just above the 555 RHS of the Brd (Red circle in picture below), I have also had to replace the ceramic cap next to it on the left on one occasion to fix a reset issue.
