Well, your power supply has bit the dust.  I just had mine replaced two
weeks ago for the second time.  I have appleCare now thru March, so if
anything goes bad on my system, it gets fixed for 'free'.  This past
power supply didn't cost me any $$.

Now that I have had AppleCare I wouldn't do this, but you need to see
Larry Pina's book, "Macintosh Repair and Upgrade Secrets."  He details
how to fix the power supply.  99% of the problems are the result of a
bad flyback transformer.  These transformers are cheap (<$20?) compared
to a new power supply (~$320).  If you aren't technical, get it replaced,
get AppleCare, and suck up the loss.  I'm praying my mouse and disk drive
die before March so I can get those replaced, too.  

My mac plus had the same problems:  screen jitters, deformed display (mine
was 1/4" taller on the left than the right), and blackouts.  Mine also
made real high squealing noises.  These are all indications of a bad PS
according to Larry Pina and my past experience.

Sorry to break the news to ya,
Brent
