Well..bang!
On my desk at my office, I've got a 3000 0'30-16..It was working fine when I
left (screen saver displaying the time)..Came in yesterday, moved the mouse WB
came back clicked on the icon for one of my harddrives, the window opened but
never finished displaying what was on the drive…(sigh). I turned off the
machine and turned it back on and–nothing..plain white screen. No drive
activity, nothing. I opened it up and disconnected the drives; still nothing.
I don't get a WB disk prompt, just the white screen..
Can any of you longtime Amiga take-it-aparters,fix-it,put-it-back-together type
of people give me a clue..
Unfortunately I don't think the company is going to want to fix it for me (we
don't do alot of Amiga stuff anymore). They'll want me to settle with my mac
and pc…ick poo blah!@#@!
thanks all..

Alex,
I *believe* that's a CPU error.

Alex,
I've seen the 8520's do this sort of thing. One of the 3000's I worked on
had an 8520 that literally fried- it got hot enough to burn the fingers.
Another system had a flakey clock delay line- after about 4 minutes it
heated up and one of the delay taps faded away… that also caused a grey
screen if you tried to reboot after it failed. There are a lot of things
that can cause the grey screen.
For a first attempt, I suggest opening the machine up & pressing down on
the socketed chips and the Zorro daughterboard.

Alex, I have already read the other 2 replies, I hope mine is a better
solution for you. It sounds like mabe your hard drive went bad. I say
thisbecause It happened to me on my A500 one time. I had just recieved my
A2000Impact series 1 SCSI card (this was in 1989, and the card had no hard
driveon it, just 2MB RAM), installed it in my ToolBus expansion chassis,
and uponturning my machine on, I got nothing but a grey screen. It turns
out that Ihad the SCSI card set to AutoBoot, and there was no Hard drive
to boot from,so it hung there. I don't know if the A3000 has a way of
dealing with harddrives in this situation, but turning off AutoBoot fixed
my problem until Igot a hard drive. So, just check out your hard drive,
make sure it spins atleast before going after the hard-to-find chips.
Good luck!

Before trying anything radical, completely disassemble the system (drive
bays included) and press EVERY socketed chip into place, including the
memory ZIPs. I've had to do this a couple of times over the past few
years due to various odd symptoms resulting in no-boot situations.

Way ahead of you..unfortunately no luck so far (thanks all for suggestions).
I pulled everything out. I don't think it's the harddrive (disconnected all
drives from the bus and still nada (no WB prompt).
I thought it might be something to do with RAM (I had installed some new zip
stuff last week) but it doesn't look like it. I pulled all the zip ram and set
the jumper (J852) to the 256×4 position and tried it with dips. still
nothing…
As for a possible cpu error I guess I could take my 3640 (2640?)..my 0'40 board
out of my tower at home and stick it in this machine to see what happens..I
know it won't fit right but it's only a test so I figure I can keep the drive
frame high enough to see if it works. Since the board is in a 3000T now I
shouldn't have to be changing jumpers or anything should I (my tower was an
0'40 from day one so it doesn't have a processor on the motherboard)?
I wish I had a set of spare chips that I could swap out with (I don't feel
inclined to start pulling all of the chips out of my tower)..
Any other suggestions all?
