(This is a paraphrase of a similar message posted on comp.sys.amiga. hardware). I'm in the midst of a peculiar dilemma. One night my Amiga's screen just went blank (I have a 2500/20) and when I tried rebooting, nothing happened. When I tried resetting, the power light would flicker, then the screen would turn grey, then the power light would flicker, then the screen would turn grey, etc. etc. goto 10. I am still able to bring up the system mode menu, and when I select 68000 mode, I get a GURU (9100009.41F900F or so), but then the system works. I'm completely at a loss as to what to do here. Obviously the 2620 board can't be utterly fried, since I can still get the 68000/68020/UNIX menu, and I did once get the thing to boot in 68020 mode properly (I have no idea how, and I have not been able to reproduce this quirk). Does anyone have any ideas as to what might be wrong, and/or what could be done to fix it? Please help, someone. I don't want to have to use my (gasp) Montgomery Grant 2-year warranty. I'll probably never see my board again... <Whimper>

In my machine the 2620 board is just a shade on the long side for the case and over time it has a tendency to work itself loose. The effects of this can be; 1. Unexplained intermittent crashes or 2. An inablility to boot. Open your case, remove the 2620 board and put it back (firmly) in its slot. I'll lay even money that your problems will vanish. John Munsch

I don't want to have to use my (gasp) ** End of Quote ** Sound initially like a loose 2630 board. I would re-seat it, and make sure all the chips on it are set well. Check all connections, etc. Of course, turn your machine off and make sure your static free.
