For some time now, I've noticed that the screen of my Rainbow will do an
occasional flickering 'dance' for a while.  There was a message posted some
time ago by Larry Campbell which suggested that the culprit was, in his
experience, usually the ribbon cable which connects the power supply to
the system board.  I just installed a new cable, but guess what?  It still
flickers!  Now, I'm almost too scared to consider the next logical culprits
- something in the video system?  Like many people, my Rainbow was paid
for using personal funds (as opposed to being a machine I use solely at
work) and we all know the huge repair/replacement price tags.  Anyone have
a clue about what I can try next?
