You get a chime, so POST is successful. What form does the 'endless blank screen' take? No activity at all? Grey raster? Pointer present or absent?

You rilly, rilly orter poke around these forums to learn about the startup sequence of 68K Macs, the milestones and when they are reached, what Happy Mac and Quizzical Floppy are on about, and what you need in the way of larger hammers and big guns for troubleshooting. Go on. You know you want to do it.
