Hey everyone.

So I did a little bit of searching on here first, but i'm still not quite sure where to start going with this.

Anyways, the lisa that we have won't boot. Here's what I've got:

It turns on, the power switch glows, no beeps from the speaker, the display shows a weird pattern (see attached image), and the floppy drive continually clicks like its trying to eject a disk.

Sooo. I tried booting it while removing things:

-No Memory Installed: Same boot up as above, no beeps, weird display, floppy clicks.

-No CPU installed: No beeps, floppy clicks, *no display* active however.

-No CPU or I/O installed: Lisa turns itself on and off repeatedly as soon as its plugged in. No beeps, floppy clicks, no display.

I've also tried disconnecting the floppy and obviously it still doesn't boot. I just don't have to listen to it click.

Any suggestions? I'm not sure where to go next. Could it just be a bad power supply? Or is this the sign of something bigger than that?

Any advice at all is greatly appreciated.

Thanks,

Andrew
