Is it really impossible to either trace out the schematics or to fix it
No it is not, but...
If so, why?
Time is a big problem. I get precious little time to spend with my
computers and I certainly don't get large blocks of time, 30mins - 1hour
is typical. (I certainly don't resent not being able to spend more time
with them as spending time playing my daughter is great fun.)
A schematic is not always necessary for repairing
Is the Lisa PSU so different from all other SMPSUs? A
lot of those are
easy enough to fix.
...but if you have little or no electronics experience then it can seem
rather daunting, given what I heard about the large voltages/current found
inside these things. Heck I don't even know how SMPSUs work.
