This means that:
- the self test passed - your memory is good (probably), so you should see an image - you need a keyboard and mouse
So, you need to address the no-video issue.
Did you try the white contrast/brightness knobs sticking out of the back of the Power Supply? If misadjusted, the screen will be black.
Can you see the CRT filament light up?
I suppose some voltage measurements on the video board come next....
