I'm not completly sure why it would go only blank. However, an A1000 will not boot without a kick disk... it does not have a built-in kick rom. When I still had a functioning A1000, it was not uncommon for the computer to be completly blank through the loading of the boot files from the kick disk. I would have a completly white screen until the blue AOS 1.x screen came up. Though.. this would usually only occure when I had the kick disk in the system before I powered it on.
