This also happened to one of my Macs (vintage 1984).  The problem in almost 
all cases is a deteriorated solder connection on the "Analog" board.  In my 
case, it was on one of the Molex connectors.  I would suggest both of you 
check with some of the "refurbishing" places that have been listed in the 
Mac newsgroups lately and get your Macs fixed (it should be relatively 
inexpensive -- DON'T take it to your normal dealer, because they's just swap 
out the board and charge you an arm and a leg).  Note (as the two above 
probably have) that this problem ONLY affects the video display -- the logic 
portion of your Mac is just fine (although it is scary as **** the first time 
it happens!).
