If the "rippling" is a quick, jerky, kind of thing, yes, you are sooner or
later going to need a new analog board. I bought a 128K Mac soon after they
came out. About a year ago, my video display began to spazz out, especially
during the first 15 min after warmup. Eventually it would stabilize. Then,
about two months ago, the problem began to get worse and worse, quickly. One
day I turned the Mac on and there was nothing but a bright vertical line on the
screen, so I got the analog board replaced. I heard a rumor there were a lot
of these problems with the first Macs. My new board has a much brighter dis-  
play; I used to keep the brightness control pretty much full up, I keep
it at about 75% now.
   The moral: Live with the problem as log as you can, but eventually you'll
need a new analog board.
