First I would open it up (remove the cover) then try
re-seating all the chips and cables that could have
loosened in shipment. Try booting again.
If that doesn't work then try disconnecting the harddrive
and boot from floppy.
If that still doesn't work, then you'll need more technical
knowledge than I have.
But then you can post the results of these tests and I'm
sure someone here can give more advice based on these
results.

BTW check for battery damage while you have it open.
If the battery is old or looks bad, REPLACE it.

The battery on my A2000 is at the front of the machine
about the middle, almost under the middle floppy drive
slot. And yes, its a barrel shaped thing about 3/4th of
an inch long and about 1/2 inch in diamiter. It most likely
needs to be replaced. I replaced mine with a 3 1/2 volt
phone battery. If you are unsure how to go about replacing
it, do a search of the older threads here on A.org.
There should be something on it, if you can't find anything
then ask here on A.org. Someone will explain how to do it.

Back to your boot problem, try pulling all the cards from
the card slots. Just a bare MotherBoard with the floppy
drive. Boot from your WorkBench disk. Unless you have
a bad WB disk or more serious problems on the motherboard
it will boot.
If you can get that far (boot on floppy) then its trial
and error to find which add-on card is causing the problem.
If it boots on floppy then add something (Harddrive maybe)
and try booting again.
