I recently acquired a used Macintosh SE, 4MB RAM, 2x 800k drives + 160MB IBM SCSI Drive (internal and Apple Labeled IIRC). It came with some nice extras but the floppy drives weren't working properly.
Wife and I disassembled the SE, discovered we actually had a 1.4 MB floppy drive (just needed cleaning & lube) and an 800k floppy drive with one of the heads ripped off. The hard disk was just mounted by one screw and the two floppy drives were both in a bottom-style cage (1 of which was mangled.)
Well I wanted it fixed up, so we removed the bad floppy, lubed the other, replaced the logic board with a FDHD version and added the correct upper drive cage. I even 3D-printed a slot cover for the upper bay because I couldn't find one online.
The SE worked great; it powered on and booted from hard disk, floppy or external SCSI drives just fine. Then we had to move everything out of our condo temporarily and the movers packed it up (and several other computers) and hauled it away.
We finally moved back in and unpacked the computers. All of them work (so far) except the Mac SE. Flipping the power switch results in a black screen and no startup bong/chime however the fan and hard disk do spin up. It doesn't seem to boot though.
I've checked the Dead Mac Scrolls, the SimasiMac page as well as skimmed the classic mac repair guide here. Nothing seems to fit my particular symptoms. There is no crackling sound, or any other for that matter besides the fan and hard disk. There are no strange odors (yet, at least.)
Could it just be a loose power connector to the logic board? Hopefully we won't have to repair the logic board. Wife and I will open it tonight to check on stuff (I am disabled such that it would be difficult for me to open the machine by myself, or I would).
Any ideas, oh wise and way more experienced liberators? Thanks in advance...
