Sparc 20 won't boot and won't display errors, either.

I would recommend hooking up a monitor anyway.  The system can be programmed to
display only to the screen and not the TTY port, although that is a very, very,
VERY rare occurrence.   You *MIGHT* - and I stress might - get error messages
that way. Keep in mind this this is a very long shot, but at this point you
need to check out every possibility.

The other thing to try would be to remove the hard drives completely.  Restore
the system to the exact same configuration that you had when you received it
and reseat all memory chips and hardware.  It is possible that something came
loose during shipping.  The system should still come up, although (obviously)
it won't be able to boot anything.  That way you can rule out that the problem
is your hardware.

Good luck!

1. Sparc 20 won't boot and won't display errors, either.

Take the video card out and see if that helps - I had a system recently that
would not do anything because of a bad video card.
