Hello everyone,

I recently acquired an Amiga 2000 and am having an issue with it. The first time I switched it on, everything worked fine. I was able to see the screen asking me for the Workbench disk.

But now the screen shows nothing and the power LED blinks all the time. I'm using a CRT television, so I can't see any color, sorry.

If anyone can help me with this problem, I would be most grateful. Thanks.


If the battery hasn't leaked on the board and eaten some traces, then it is most likely a case of you need to pop the chips and reseat them. it is common with old sockets etc. use a proper plcc puller for the custom chips so you dont break the sockets.

Thank you guys for your replies. I have already reseated most of the chips, but no luck. Should I have done that to all of them?

When it comes to the battery, I did remove it immediately when I received the computer. Unfortunately, the battery has leaked, but nowhere near as bad as the pic you have above. I'll try to take a picture of that area so you guys can see if the damage is really bad.

I forgot to mention that the Amiga power LED would blink for 10 times and then an 11th time for a little bit longer. After that, it looks like the screen would "reset"(or flash) itself and continue all over again.



Thank you for the warm welcome :). I hope to get this machine running perfectly so I can contribute more to this forum.


check psu voltages first.

Reseat all socketed chips-anything less is pi**ing in the wind, check the pins and sockets for any blue green corrosion. If the original batt leak was not cleaned up it may of continued eating traces until one was broken, or also it is conductive so it can short them also. badly corroded sockets need replacing,and if the chip pins cant be cleaned,they also can.

the 10 short,1 long caps light suggests agnus.. pull it,be sure it has no bent pins and all are clean-check the socket well, and reinstall.

Some good pictures of the battery leak area would be great!
