Be wary - there have been threads full of people who sent their hardware for repair never to see it again...
-edit-
What exactly is the problem anyway?
Bear in mind that you may need to terminate the ppc.library for warpos to work etc...
Can you get to an amigados early startup screen?
There have been times when my blizzard has gone nuts and I have had to reflash it. It recognises my 040 but nothing else (no ram, ppc, scsi, gfx card). After reflashing it all works perfectly again.
If it is just hanging during booting there could be any number of software problems going on.
