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?

Strange. Open it up and carefully reseat any cards or socketed chips. Also check for battery damage and make sure your power supply is healthy.

could be 68000 cpu needs cleaning plus socket needs cleaning.  battery leak???

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?

The most common solution for a leaking battery is to remove the bad one and don't replace it at all.  A battery isn't necessary on the Amiga.  If you insist on having a battery, look on ebay and get a kit to install the common "coin" shaped battery.

You only need the battery if you want the 2000 to keep the date/time when it's turned off. If you have any other Amiga's make sure you remove the battery before it destroys the motherboard.

Firstly i would remove the old battery and clean up the mess and get it working again. The A2000 will work fine without a battery. I had removed mine before it leaked and never bothered replacing it. My A2000 works fine.

Make sure you really clean out the mess using a good PCB cleaner. Then they say it is also good to use some sort of lemon juice or something to kill the corrosion.

Get a DMM and check the traces to make sure none are damaged. I had an A500 Plus where the battery leaked and damaged a trace. Managed to fix it by soldering a wire from one point to the other.

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.

I would also carefully remove the processor and clean the socket and pins using the PCB cleaner. And maybe use some lemon juice to neutralize the acid.

[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...

You used a ph 2.3 acid to clean up acid damage?

[dougal]

Do the tracks look damaged ?

Haven't you learned yet?

[dougal]

I would check the tracks / traces around the area were the battery acid leaked using a digital multimeter to check for continuity. If any are damaged you could try bridging them using single core wire. I had to fix an A500 plus that way after its battery leaked.

[Jaycebot]

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