Bit of an interesting problem this one.
I recently picked up a Macintosh SE FDHD which had suffered a battery leak, however, the logic board did clean up relatively well and it appears that no traces had been damaged.
Powering it up showed signs of life - it would bong, pass the memory check and would show the cursor. I could easily move the cursor around, so at least the system hadn't frozen, and at least ADB was working.
However, the blinking floppy, happy or sad mac icons just never appear. I've tested it with known working drives, and I have been able to prove that the ROMs and SWIM are still working by putting them in my regular SE. I'm guessing that either a via has became damaged or an IC has failed, but I'm not sure where I should start to check.
Any suggestions are welcome!
