Nah, red screen on an A3000 is either a poorly seated ROM or it's a bad ROM. I think I have some A3000 ROMs here (none are 3.1) if you end up looking for one to try.
[If you decide to try the agnus... never ever ever try to leaver a plcc chip out of it's socket, you'll end up cracking the socket (and might not even notice) you're better off using some form of tool that is an L shape and simply hook it under one corner and pull straight up. Even if you bend a leg or two you can always straighten them out. It's not fun to have to replace the socket though.]
