Amiga 4000 revD?

[spaceman88]

I had one of these ( it was a "Video Toaster" model), no 68030 on board, had an A3640 with the capacitors actually installed correctly. It had a black screen when I got it, so I sent it off to Anthony Hoffman in NZ, but he was unable to fix it.

Odd you should add this post; I bought a CR version like the one above from someone I really trust who told me at least twice what a sweet motherboard it was.  I waited a month to get it tested and it is quite dead.  I am now waiting for Anthony to get back from the deep south in October to see what is wrong.

I found out later that the power supply was also bad in this system and wondered if it may have fried the board. I'm not sure what kind of over voltage protection those power supplies had. I also sent Anthony a "regular" 4000 board (bad caps, battery damage) at the same time, that he was able to fix.

Just curious, is there issues with the a3640 version 3.1 as that is what it came with? I know some had issues with caps or something being installed backwards?

On my rev. D the 3640 ver. 3.1 the caps were installed correctly (they looked wrong if you went by the markings on the board), but you would have to compare yours to some pictures on the Web to be sure.
