4000T won't boot !!!

[billchase]

My 4000T refuses to boot.
1.  Lights and all drives power up
2.  Video signal initializes
3.  Stripped all zorro cards out
4.  Same results with original 040 board
5.  Replaced disk and A/V modules (not 100% that
    the replacement A/V module is good)
6.  None of the start-up pre-boot menus will activate
7.  Will not boot from floppy
8.  None of the troubleshooting codes or the workbench
    disk animation will display.

The machine basically powers up, the monitor kicks in
and everything just sits there. I was in the process
of removing and installing various expansion cards
(of course with power off!).  I must have made some
careless mistake, but not sure what I would have done.
Thanks.
 
Specs:
4000T with Phase5 060/604e 128MB
Picasso IV
OS3.9

Thanks!

I will check that out, but I am afraid it something
more terminal.  Hopefully I'm wrong.

Someone mentioned about the Caps Lock key.
It does light/unlight when pressed.  The battery
is the coin type which has been replaced (mounted
a socket for easy replacement).  All the simms are
mounted on the 060/604e board, none on the motherboard.
Still haven't swapped floppy cables yet.  I was in the
process of swapping various zorro cards around.  Only
thing I can think of is that I left the power cord
connected while doing so.  Thanks for the help!

I disconnected the scsi and floppy cables, still
no kickstart screen.

If I am not mistaken, the chip ram is soldered to the
motherboard.  All the simms sockets are used as fast ram.
I actually haven't used any simms on the motherboard
since I installed my cyberstorm with max ram a few years
ago.  I have seated and reseated the cpu card with no
results.  I am afraid the problem lies in the A/V module
(the machine will not boot without it) or possibly on the
motherboard.  I have a PIV graphics and have also tried
booting the machine using the native display.
