Just a guess, but the last few SE30's I've
come across have all had
at least a few dried out capacitors causing problems.. This could be
the reason for problem 1.
Yes, but one should be really really careful. In fact, the caps are
dried out, because they leak their inside onto the board. This
corrosive liquid creeps everywhere if it isn't stopped by excessive
dust on the board.
I killed two boards by cleaning with too much solvent. I suspict some
chips aren't leakproof anymore. The cleaning liquid got inside and
destroyed somehing in there.
Being really really careful, cleaning the cap fluid contamiated areas
with with a q-tip and some solvent (I use Kontakt WL) is the first
step to go. Then, re-check if the machine's still working. When it is,
change caps and the machine will hopefully do another 25 years.
These are my records about my latest repair. Sorry for the bad google

If I had time and knowledge of this digital stuff, I'd start a project
for a replacement board for the SE/30 with modern components, being
fully compatible to the old one.
