I poked around some of my documentation, it looks like vertical
stripes represent issues with the power board or mainboard.  Turn
the thing off for day and carefully remove the power board (vertical
board on the side).  Inspect the solder joints to see if any are
broken, if so a soldering iron can fix it.  Ensure there is no
damage to the electrical components themself (leaking or bulging
capacitors, exploded resistors, blown fuses, etc.).  It is a tedious
job, it is easy to miss problems, and the problem may not even be
visible upon inspection.

Just be careful while working around a CRT, and don't work around
one unless you are comfortable with it and very cautious.  A CRT
can store a lot of charge -- which is why I suggested waiting a
day, so it will hopefully bleed off.  CRTs can also implode.  I
haven't seen the consequences of either, but I don't want to hear
first hand information about folklore becoming reality!  That said,
things like cold joints are easy to fix.  I have done so on a few
SE and SE/30's myself.

The hard drive will spin up when it receives power, so that doesn't
tell you anything about the mainboard.  I checked the power up
sequence on my SE, and the floppy drive makes a sound as soon as
it is powered up so I'm left to assume that it behaves in a similar
manner.  The fact that it receives power from the mainboard doesn't
mean much, since parts of the board may be functional if others
are toast.
