Hi 23703jim

Have a good read of this thread, I have the same problem as you.  

http://www.amiga.org/forums/showthread.php?t=27561

I have performed some repairs on broken internal traces to the CPU, which as you will see in that thread are caused from overheating.
Took me hours to map out pins from the processor and FPU sockets to the surrounding chips, but I eventually found two broken traces, it still didn't work after repairing/wiring them, I brought a number of used 68030's and have tried replacing CPU's, no change.  I have tried a new crystal oscillator.  I have checked all the contacts on the 86way edge connector back to the chips on the motherboard.  Everything else is checking out correctly, only found two problems which I fixed.  But still nothing.  

Good luck, let us know what happens. :-)

I haven't finished with mine yet, it'll come out for some more study/testing soon.

Yep I did all that stuff and lots more, only to get a big fat nothing.  As described, the screen stays dark and it does not boot at all.

I'd keep the board, he will probably throw it away.  Even a dead Amiga board is worth something.  Even if just for parts.  Better than the bin.  

I wouldn't mind another for parts and to attempt to get one out of two working.
