Google will give you links to a hundred different pages that tell you a green screen is indicative of a chip memory problem:

http://www.amiga.org/forums/archive/index.php/t-4216.html

Etc.

Now if you want to really solve this problem you're going to need to post more information.  Have you tried removing all cards?  Reseating all socketed chips?  Has the battery leaked, or has it been removed?  (leaking batteries can cause all manner of havoc to an Amiga motherboard)  Etc., etc.

The first thing is to reseat the chips after cleaning the contacts as it may just be a contact problem (Agnus?).

Doing things like reseating all of the custom chips and cleaning sockets won't cost you anything but time, same as researching and learning about the potential causes of this problem.  Unless your battery has leaked all over the board there's very few things an A2000 can't be recovered from.  ;)

There can be numerous problems that show this as a symptom. Have you checked the battery on the board? They age, then leak, and then damage the traces.

Why? Just because the battery is removed does not mean that it didn't do any damage to the board before...
