amiga 2000 suddenly dead, what happened?

[Jaycebot]

Ive had my amiga for about 6 months now. Anyway  I had some friends come over yesterday, and i was showing them my various antiques and vintage stuff. When i went to power up the amiga 2000, all i got was a yellow screen with rapidly moving diagonal black lines. The harddrive light didnt come on, and it wont respond to a floppy disk in the drive.  What in the world happened?

Well I think I found the problem.... The battery leaked and some of the acid got on the pins of the processor, and it's all corroded. So that's going to need cleaning.  Where can I get a replacement battery?

[Jaycebot]

Ok, thanks for the info!  I'll just remove the battery and clean the PC board.  The clock feature doesn't really matter to me.

[Jaycebot]

Well, I took it apart, removed the battery and cleaned the cpu pins and socket.  I used lemon juice as well to get rid of the acid.  It still doesn't work...

[Jaycebot]

I checked the traces, theyre fine.  However, this morning, I powered up the amiga, and now im getting a green screen.

[Jaycebot]

Yes, i disconnected all the Zorro cards, I get a white screen when they're removed.

Where are the vias located on the board?

[Jaycebot]

the vias are all over the board. The ones you need to check, are the one surrounding the offended area ( vias are that little round silver like things .... they are like bridges that interconnects traces between the 2 faces of the PCB and can be affected/corroted by the acid)

Ok, Thanks!  I'll check em.

[Jaycebot]

Well, I checked the connections around the battery area. They're all ok.  
What if the problem wasn't the battery leakage?
