Yes, I've eliminated the drives and will have to inspect the
electronic parts on the PAV board. I assume these can be replaced
rather easily? Thanks for the cautionary tips for electric safety.

The replacement process isn't difficult, just time-consuming. Whether
it's your first or your xxxth, it's just a tedious task that doesn't
respond well to speeding it up.
But first, get a copy of the appropriate Apple Service Manual and
Video Adjustment Utility for your machine. (These are available a lot
of places, all of them safely out of the reach of Apple's lawyers,
who don't like their copyrighted material -- even for no longer
supported Apple products -- to be available in public.) These
official how-to-do-its will tell you all you need to know, including
proper safety procedures. The only thing I had to obtain to do PAV
replacements was the jumper cable needed to make permanent
adjustments in the color and geometry panels when replacing the PAV
boards. I just made one up out of some heavy wire and wire
connectors. A light meter would be nice, but I've managed to learn
how to adjust CRT displays satisfactorily without one.
HTH and good luck!
Jim
