If you own an Amiga, especially an A4000, read this!

Creepy.  As  I was reading this topic my A4000 died.    That is REALLY creepy.  I looked at my CPU board and it looks to have this problem.  I've tried to replace the caps and the problem is still there and that may owe to my high skillset for surface mount repairs.  I think it's time to just get an accelerator card for the machine.  Any recommendations on a decent one that wont break the bank?

Well my problem was the CPU board.  It is this issue as well that was preventing it from booting.  The caps were in backwards and had indeed failed.  I have verified this by testing voltages under power.  I actually replaced all 5 capacitors and the board works beautifully.  

My board revision is 3.1.  In addition I did verify that the silkscreen on the board was also backwards for the three caps in question.

Many thanks for posting this article, and many thanks to Anthony at http://amiga.serveftp.net for his assistance in providing the info on the site and in the many emails we exchanged.
