HELP diagnose IIsi failure

After reading this newsgroup for some time, I now have cause to make a post.

Problem:

My IIsi will no longer start up; it only gives me a 4 tone tune. I assume
this is some warning that the startup process has found a problem. The
computer gives the usual ping when starting, spins up the hard drive and
makes the clicking noises as it starts to run files, then the tune. The
monitor does not light up so I don't even see a sad mac icon.

Lead-up:

The IIsi (running 7.1) was linked via modem (2400bps) to my uni's VAX (using
MicroPhone II v4) and in the process of displaying a file. The software
bombed and displayed an error box, but before I could read it, it started
jumping the message up/down in the box. Fine, although I've never seen this
before, I interrupted (control-esc), which quit the program. Finder stayed
up for about a second then froze. I reset (control-option-esc) and got the
tune. The modem was still on at this time because the line does not fall out 
immediately and I can usually just restart and reattach my terminal session. 
The IIsi has failed to start ever since. I have tried deattaching the
printer, external drives, modem, keyboard, monitor; booting from internal,
external hard drives and disk tools disk. The monitor only lights up when
using the reset.


Help:

Any ideas? I know it will need to go in for repair, I would just like to
know what for before the techs start babbling jargon at me.

One more month and it would have been traded/sold for a PM7500!

Thanks

While it's possible it's a problem with the computer, it sounds like
something in the system got damaged.  The easiest solution is to
re-install the system from floppy.

Ensure that all external SCSI devices are powered on (and that their
terminators haven't fallen off) before starting the IIsi.  I have a IIsi
and once got the "chimes of death" when I forgot to turn on my cartridge
drive first.  It now works fine.  If this doesn't help, try zapping the
PRAM.  It's amazing how many weird problems this will fix.

I _really_ hope this isn't the problem but the chimes of death are most
commonly caused by faulty RAM. Try removing the RAM and starting up the
machine. It's quick to do, so you can find out nice and fast if that's the
cause. Make sure that you keep yourself grounded at all times when inside
the machine however (you can do this by keeping the unit plugged into the
power outlet (but switched off!) and keeping yourself in continual contact
with the metal surrounding the power supply). If you need detailed
instructions about this, just email me.

If it is the RAM, check with your reseller to see if it is covered under
warranty. While some resellers may not like you to know this, quality RAM
is usually covered under their suppliers warranty for life (no, not the
life of the RAM which just died!). If you didn't buy from an Australian
Apple Reseller then you SHOULD HAVE SUPPORTED THE LOCAL MARKET!
