Boy, Kevin, are you in luck!  This looks like an easy one!

The Apple //e (and //c, and I assume the //gs) have a built in self-test
routine.  On the unenhanced //e the routine clears the hi-res screen to white,
then to black, repeats this, then says "Kernel OK" if everything is
hunky dory.  (The //c and the enhanced //e do the test by filling the lo-res
screen with garbage, messing around with it a bit, then displaying "System
OK".)  The self-test is invoked by holding down the solid-apple (SA) key
and resetting the computer.  Turning the power on is the equivalent of
resetting...

My guess is one of three things:
    1) Your SA key is stuck down.
    2) You've got a joystick or paddles connected, with one of the buttons
       stuck.  (SA is hard-wired to button(1) through an OR-gate.  They
       do exactly the same thing.)
    3) There's a short circuit somewhere in your machine making it seem like
       SA or button(1) is always pressed.  Since you've got some hardware
       experience, it shouldn't be too hard to track down the error.
       If you can't track down the problem easily, you might want to
       pick up Jim Sather's "Understanding the Apple IIe" (published by
       Quality Software, 1985) for such handy things as schematics and
       other details about the computer's innards.
